Wrought iron. About 60% less energy is required to produce steel from recycled materials than its production from iron. Density: The metal has a density of 7.8 gm/cm3 and a melting point of 1500 centigrade. Non-ferrous metals are also more resilient when compared to ferrous ones. As the most common types of ferrous metals, steel waste is recycled to the most. Various types of ferrous metals and alloys are available in the market: Carbon steels are ferrous alloys that contain carbon and small levels of other alloying elements, such as manganese or aluminum. Ferrous alloys or metals are metals that consist mostly of iron (Fe). Metal cuttings or imperfect products are recycled by remelting, recasting, and redrawing entirely within the steel mill. While composed primarily of iron, differing amounts of copper, vanadium, tungsten, manganese, and other elements can be used to tailor an alloy steel to have higher toughness, ductility, tensile strength, hardness, and other properties. Gray cast iron. Carbon Steel. Some, however. The grey color is due to the presence of free graphite. However, the Steel, containing Iron and carbon, is not referred to as an alloy. The alloying elements used are; nickel, chromium, molybdenum, and vanadium. It is specially used in the manufacture of Steel in the Bessemer process, because of its freedom from sulfur and phosphorous. Non-Ferrous Metals; Types, Uses, Properties [Complete Guide] Iron is actually the only metal that “rusts” by definition. Chromium makes the Cast Iron extremely tough, strong and ductile. Why is it that ferrous Alloys have low electrical conductivity. Wrought Iron:. These metals are not magnetic, which is one way you can determine for yourself what type of scrap metal you are dealing with. Formwork (Shuttering) for Concrete [Its Types, Design]. The source material for the manufacture of Wrought Iron is PIG IRON. Besides the ecological benefit of metal recycling there is also an economical benefit. The strength will be greater in the longitudinal direction.

Great tensile strength 3. What is Scaffolding? So, finally, Ferrous Metals List comes to an end. i.e., in the form of cementite, also known as Iron carbide. They can be sub-divided into 2 types on the basis of the proportion of alloying elements, which are the following: Read More: Abrasive Definition and Types of Abrasives its Forms and Applications. A list of ferrous metal properties: 1. Metal recycling is the process of separating, cleaning and melting ferrous and non-ferrous scrap so it can be used again as a raw material for new products. Examples of ferrous metals include carbon steel, mild steel, stainless steel, cast iron and wrought iron. The Iron obtained is known as Cast Iron, and the shapes obtained are called Cast Iron castings. Pig Iron is the first or basic form in which Iron is prepared as the metal from its ores. Some internal recycling methods are obvious. It is very strong, hard, and resistant to Wear and Tear. Brinell hardness number of 105; tensile strength of 35,000 psi; specific gravity of 7.7; a melting point of 2750°F (1510°C); and is ductile and corrosion resistant. These are Steels made with the addition of a definite proportion of a selected element or elements in addition to carbon at the manufacturing stage. Pig Iron, because of its impurities, is weak and hence very... 3. It is soft in character and rich in carbon. This is explained by a number of reasons: 1. And quite brittle as well. Its properties can be varied over a wide range by varying its composition and by subjecting it to various mechanical and heat treatment processes. Better results are obtained when Pig Iron with alloying elements are heated in an electric furnace or air furnace. Metal is a material which can be recycled over and over again without degradation of its properties. Ferrous metallurgy represents roughly 90% of worldwide production of metal. The purpose of alloying is to improve the properties of Steel, like imparting the fine grain size, to improve the hardness, toughness, strength, corrosion resistance, etc. Carbon is the only controlling component in them besides Iron. Recycling steel saves a lot of energy, natural resources and reduces harmful emissions to the atmosphere as a result of ore production. 8. Thus all the Steels, in addition to Iron and carbon-containing other elements such as; nickel, chromium, manganese, silicon, vanadium, molybdenum, tungsten, sulfur, phosphorus, etc., are called as alloy Steels. It has high tensile strength, toughness, and wear resistance. Ferrous Metals. The first steel pieces were found in modern-day Turkey and date back to 1,800 BC. It is produced when the raw material is burnt at a very high temperature. Carbon Steel. Following are the common types of Cast Iron used in engineering materials. The Importance of Guard and Hand Rails In Industrial Workplace Safety, Precast Concrete: Its Types, Advantages, Manufacturing. The definition of a ferrous metal is any metal that contains iron; non-ferrous metals do not. Cast Iron is derived from the Pig Iron. METALS. What is metal recycling? In white Cast Iron, the entire carbon is in combined state. 2. Ferrous Metals List | Their Types and Properties: 1. It is, therefore, impure and crude and requires subsequent processing to develop Cast, Wrought Iron, and Steel, which are the common Ferrous Metals used in construction and industries. Cupola furnace is cylindrical in shape with an almost uniform diameter (about 1 meter) and a height of about 5 to 6 meters. Pig Iron is the first or basic form in which Iron is prepared as the metal from its ores. zinc). The Iron obtained is malleable as well as ductile. Alloy cast iron. Cannot be tempered or hardened like steel. Different types can be cast, hot forged, cold-forged, cold-rolled into sheets, drawn into wires and extrusions for cross-section bars. 2. There are two processes for the manufacture of Wrought Iron: Its most important properties are mentioned below. It is white in color as there is no free graphite. Those give ferrous steels mechanical properties that make them widely used in engineering. It is not suitable for shock and impact loads. Steel is superior in resisting both compressive and tensile stresses. It is used in Railways equipment of a great variety. The electrical, magnetic, and thermal properties may be modified in the desired direction. Besides, Wrought Iron always contains a small proportion of slag in the silicate component. This is the first major group of Steels. It is used for pipe and pipe fittings. 3. It cannot be forged, welded, or riveted. Pig Iron:. Nickel is added to effect an increase in the hardness and resistance to wear. However, non-ferrous metals all do have one thing in common: They do not rust. properties. Coke is used as fuel and limestone as a fluxing material. The ultimate compressive strength ranges between 1500-2000 kg/cm2. It can also be classified on the basis of Steel casting. Used in compression members, bed plates, etc. It is weak in tension and strong in compression. The alloy Cast Irons are used for gears, sprockets, wheels, I.C engine cylinders, piston, piston rings, crankcases, crankshafts, camshaft, brake drums and shoes, parts of grinding machines, etc. And carbon is included in these impurities, its proportion being generally less than 0.12 percent. Any metal that has iron as the main metal in its composition is considered to be ferrous. Some non-ferrous metals are made for cryogenic applications, others are made to withstand extremely high temperatures. The elements of the composition of Steel apart from carbon are sulfur, silicon, phosphorus, manganese, etc. It is used in Agricultural machinery making and carpentry tools. This is a heavy metal that’s dull grey in color, although it becomes shiny when polished. It has high tensile strength but weak compressive strength. Read More: Test for Compressive Strength of Bricks, Absorption, Efflorescence & Size. Therefore, Pig Iron is remolded in a furnace and cast or poured into molds of the desired shape to get the Iron known as Cast Iron. Ultimately, the metal deteriorates to the point of failure. It is commonly used in castings, dies, molds, machine frames, and pipes, etc. Ferrous Metals List | Their Types and Properties: What is Paint, Definition, Properties, & Components of paints. At present, the role of ferrous metals in the engineering Industries can be easily described as most dominating. copper), low weight (e.g. The cupola furnace contains a charging door, a platform and tapping holes for the purpose of blasting the air. In all the jobs ranging from the manufacture of a primitive type of agricultural implements to advanced types of Air Crafts, ferrous metals and their alloys occupy a prominent position. Durable 2. Test for Compressive Strength of Bricks, Absorption, Efflorescence & Size. 4. If there is a free graphite present, it is a Cast Iron, otherwise a Steel. An alloy is the purposeful mixture of two or more elements of which one being in largest proportion is called as base metal, and other elements are called as alloying elements. Steel is an iron-based alloy containing typically less than 1% carbon, where iron frequently contains 2% or more carbon. It is malleable, ductile, tough, and resistant to corrosion. And in any other field of engineering activity, it may not be possible to move ahead without metals. The economic extraction of Iron from its ore. 3. Think steel, stainless steel, carbon steel, cast iron. It’s light red and turns greenish with oxidation. 9. Strength: It has a tensile strength varying between 2500 to 4000 kg/cm2. Alloy steels contain low to high levels of elements such as chromium, molybdenum, vanadium and nickel. It can be hardened but cannot be tempered. 4. Usually magnetic 4. All ferrous metals are magnetic and. The types of coins you might discover depend entirely upon the metal. Used in manufacturing of cisterns, sewer and drain pipes, manhole covers and fittings. It is used in flywheels and agricultural implements. Non-ferrous metals are used because of its properties such as higher conductivity (e.g. On the other hand, with the decrease in the carbon content (lower than 0.1%), the material would resemble more to Wrought Iron or pure Iron. 1. The carburization and reduction of the ore with Coke. 2. Tensile strength of 35,000 psi; specific gravity of 7.7; a melting point of 2750°F (1510°C); and is ductile and corrosion resistant. Besides carbon, many other metals may also be present in addition to Iron, giving rise to great varieties of Steel. iron. 5. 3. The usual alloying elements are Nickel and Chromium. Flux is the material which easily fuses and mixes with impurities to form a slag, which can be taken through the top of the furnace. ... Non-ferrous metal that is strong and ductile, casts well and is gold coloured but darkens when oxidised with age, a good conductor of heat: Hence, Steel finds most of the applications for all purposes in places of Cast Iron and Wrought Iron. 2. The ferrous materials include carbon steel, stainless steel, and low alloy steel. White iron. The outer shell is made of Steel. This type contains sulfur as the main impurity and hence is considered inferior in grade. (β-phase is less ductile than α -phase, but it is stronger and harder. 2. Because of the above set of properties, Wrought Iron is extensively used as a material for making plates, sheets, pipes, tubes, etc. The hardness and toughness of Steel increase with the increase in carbon content up to 1.7%. become misaligned, … The tensile strength of the Steel may be increased without affecting its workability. Used for rail chairs, carriage wheels, etc. Ferrous metals emerged much later when iron production started around 1,200 BC. Low resistance to corrosion 5. It is also called forge Pig Iron, as it is hard and brittle and can be converted only by using pressure. Physical: Wrought Iron is bluish in color, has a silky luster and fibrous structure. It is used for car wheels, rollers for crushing grains, crusher jaw plates, etc. Ferrous metals are those which contain iron as their main constituent or base metal. The molten metal in almost pure form is collected at the bottom of the furnace along with the floating slag. Moreover, it can be welded with ease. Steel is manufactured using one of the following processes: Steels can be classified in many ways such as on the basis of the methods used in their manufacture, on the carbon content, or according to their use. Most metals today are made up of several different elements. Outside of the foundry, steel is the ferrous … automotive parts: engine blocks, pistons, gearbox cases, cylinder blocks, No Alloys: Tensile strength of 25,000 to 50,000 psi (172,375 to 344,750 kPa), Alloys: 50,000 to 100,000 psi (344,750 to 689,500 kPa), Cylinder heads for compressors and diesel engines. Wrought Iron shows good resistance to fatigue and sudden shock. White Cast Iron is produced by melting the low phosphorus Pig Iron along with the Steel scraps in a cupola furnace. Iron and steel are widely available, strong, cheap, and can be shaped by casting. The best thing about Steel is that it has both properties of Cast and Wrought Iron – Compressive Strength of Cast Iron and Tensile Strength of Wrought Iron. Types of Ferrous Metals Mild steel and Carbon steel: Iron is combined with carbon to obtain mild steel and carbon steel. Pure Iron is of little use as an engineering material because it is too soft and ductile. In the automotive, building and bridge construction, railways, light, and heavy machinery, shipping, and transportation. It is used in rolls for rolling mills, hydraulic cylinders, cylinder heads, etc. They may have small amounts of other metals. As we noted earlier, Cast Iron is better in resisting compressive stresses, while Wrought Iron is suited to tensile stresses. Cast Iron is manufactured in a furnace known as cupola furnace. Cast Iron:. Types Of Metals. The most common ferrous metals are mild steel, carbon steel, alloy steel, stainless steel, wrought iron and cast iron. 3. Its Types, Parts Used in Construction. It is not easily machinable due to its hardness, hence, require special tools for machining. It’s non-ferrous and it has a density of 8.94 g/cm3. Types of Metal Finishing. Below are a few of the types of finishing processes available: Plating. Pig Iron, because of its impurities, is weak and hence very difficult to shape into various forms. It is used for castings where shock and impact loads are operating. - Ferrous metals are those metals which contain. A liquid slag forms when Limestone combines with earth matter. Since it … They are further subdivided into 3 subcategories. There are far more differences than there are similarities among the different types of non-ferrous metals. The Cast Iron thus obtained is in a molten state, and it is chilled, i.e., it is cooled rapidly. Even though almost all this types of nonferrous metals are costly than ferrous metals, they are used in industrial application such as: roofing pipes, electrical and gutters. Bronze, which is an alloy of copper and tin, was likely first used around 35,000 BC. 3. The resistance against very high temperature, abrasion and corrosion may be improved considerably. The usual composition of Grey Cast Iron is: It is soft and ductile. The molten metal taken out are fed into the molds prepared to get desired shapes. The top of the furnace remains open. Pig iron. The Cast Iron thus obtained, has 1.7 to 4% of carbon with small impurities of manganese, phosphorus, silicon, and sulfur. The metal which is consisting of the main constituent other than the iron is known as Non-ferrous metals. This categorization is based on the iron content. 2. When iron cools and changes from a liquid to a solid, most of the atoms in the metal pack, tightly together in orderly layers. It is poor in tensile strength and impact strength with almost no ductility. Due to these properties, Steel is used as a structural material in all types of situations. The term ferrous, derived from Latin ferrum, is used in metallurgy to indicate the presence or absence of iron.Thus, the main difference between ferrous metals and nonferrous metals is their iron content; ferrous metals contain iron as a component whereas … It is, however, the classification on the basis of their chemical composition is commonly adopted. That means each type of ferrous and non-ferrous metal has different qualities and uses. Non-Ferrous Metals; Types, Uses, Properties [Complete Guide] The wide abundance of Iron ore in almost all parts of the world. Iron (Fe) is the principal element of Ferrous Metals. Ferrous Metals Ferrous metals contain iron, and are known for their strength. Ferrous Metals. Therefore, it is also known as chilled Cast Iron. Non-Ferrous Metals; Types, Uses, Properties [Complete Guide]. Ferrous and non-ferrous metals are two different types of metals. Alloy Cast Irons are also called as plain Cast Irons. Types of metals and their uses. Examples of ferrous metals uses: Because these metals tend to be strong and durable, they have many uses in construction and engineering. It shows grey color when fractured. Cast Iron is derived from the Pig Iron. So, while metals like iron, copper and aluminum are easily detectable, you … While the process for making aluminum is a bit more complicated than some of the other metals, it’s actually an extremely common metal. It cannot be tempered or hardened like steel. We have discussed the characteristics of the different Non-ferrous metals and the purpose and use of the non-ferrous metal in different applications in this article. On the basis of the presence of free graphite, differentiation of Steel and Cast Iron can be made. Non-ferrous items tend to last longer because they are more resistant to corrosion and rust. Steel is an alloy of Iron and carbon, where the carbon content is less than 1.7%. It is the purest form of Iron, containing all impurities below a limit of 0.5 percent. It is used for automobile cylinder blocks, heads, housings, etc. The division of metals into two groups – ferrous and non-ferrous – has been formed historically. According to ASTM ferrous metal designation system, “A” describes a ferrous metal such as A106, "A" prefix indicates that this material is ferrous material. Malleable cast iron. It is also called as nodular or spheroid graphite Cast Iron or high strength Cast Iron. The flexibility that can be induced in the mechanical properties of Iron by combining it with other metals and/or by heat treatment and such other methods. It’s often mixed with other metals to produce another type of metal like bronze and brass. Ductile Cast Iron is produced by adding any one of the elements of magnesium, calcium, cerium, bismuth, zinc, cadmium, titanium, and boron into the molten Grey Cast Iron. It is suitable for highly corrosive environments such as: liquid, chemical and sewage pipelines. In the present, their role in the engineering industries can be easily described as “most dominating.”. Non-ferrous metals are those which do not contain significant quantity of iron (ferrite) or iron as the base metal. 4. Following are the major groups of Steels. While it doesn’t rust, it will oxidize. Following are a few types of Pig Iron distinguished on the basis of their properties. Recycling - Recycling - Ferrous metals: Ferrous products (i.e., iron and steel) can be recycled by both internal and external methods. Recyclable 7. Ferrous Metals • The ferrous group of metal include all types of Iron, Steel, and their alloys. 1. • It is typical of this group that Iron (Fe) in one form or another, is the principle component of all ferrous materials. Alloy steels are a type of ferrous metal specially formulated to serve specific purposes. Beyond 30% Zinc, the tensile strength increases up to 45% of Zinc, but the ductility significantly drops. As the name indicates these are the metal combination of Iron with carbon. Carbon steel is a ferrous alloy with 0.05 to 2.0% carbon, and is known for its high … If the carbon content in Steel exceeds 1.7%, it does not combine with the Iron, but it is present as free graphite.
