It is commonly asked whether carbon steel is harder than mild steel, but this is another trick question since mild steel is a type of carbon steel. There is a difference in hardness between the different types of carbon steel. Generally, the higher the carbon content in steel, the harder the steel is. However, this also means that the harder the steel, the more brittle it is. This means that high-carbon steel is harder than low-carbon steel but is also more brittle.
This balance between hardness, ductility, and malleability makes mild carbon steel the ideal choice for most applications. All steel containing carbon as the main alloying element is carbon steel, but the amount of carbon present dictates the type of steel and its properties.
Here, we break down the differences between mild steel, medium carbon steel, and high carbon steel. It costs less while providing the material properties needed for most industrial applications.
Mild steel contains approximately 0. While mild steel has a lower tensile strength than other carbon steel types, it is more pliable and easier to form. You can also harden mild steel with various treatment processes.
Mild steel is machinable and weldable, which aids in its usefulness for most applications. Taylor and Francis Publishing. An Introduction to Materials Science. Princeton University Press. Materials: engineering, science, processing and design 1st ed. Lamarsh, A. Baratta, Introduction to Nuclear Engineering, 3d ed. See above: Alloys. If so, give us a like in the sidebar.
Main purpose of this website is to help the public to learn some interesting and important information about materials and their properties. Main Menu. Mild steel has a relatively low tensile strength, but it is cheap and easy to form. Medium-carbon steel balances ductility and strength and has good wear resistance. For high-carbon steel hardness is higher than the other grades but ductility decreases. Steels Steels are iron—carbon alloys that may contain appreciable concentrations of other alloying elements.
Types of Steels — Classification Based on Composition Typical applications for low-carbon steel include automobile body components, structural shapes e. Low-carbon Steels.
Low-carbon steel, also known as mild steel is now the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications. Low-carbon steel contains approximately 0. Mild steel has a relatively low tensile strength, but it is cheap and easy to form; surface hardness can be increased through carburizing.
Typical applications include automobile body components, structural shapes e. For example, A36 steel is a common structural steel in the United States. Low-carbon steel sheets used for car body applications, for example, are subjected to a variety of forming operations, including deep drawing.
Microstructures consist of ferrite and pearlite constituents. As a consequence, these alloys are relatively soft and weak but have outstanding ductility and toughness. In addition, they are machinable, weldable, and, of all steels, are the least expensive to produce.
Density of this metal is Medium-carbon Steels. Medium-carbon steel has approximately 0. These alloys may be heat-treated by austenitizing, quenching, and then tempering to improve their mechanical properties. They are most often utilized in the tempered condition, having microstructures of tempered martensite.
This grade of steel is mostly used in the production of machine components, shafts, axles, gears, crankshafts, coupling and forgings, could also be used in rails and railway wheels and other machine parts and high-strength structural components calling for a combination of high strength , wear resistance, and toughness.
For example, a steel is a plain carbon steel containing 0. Typical uses of this type of steel include machine, plow, and carriage bolts, tie wire, cylinder head studs, and machined parts, U-bolts, concrete reinforcing rods, forgings. High-carbon Steels.
High-carbon steel has approximately 0. Hardness is higher than the other grades but ductility decreases. They are almost always used in a hardened and tempered condition and, as such, are especially wear resistant and capable of holding a sharp cutting edge. Therefore, high carbon steels could be used for springs, rope wires, hammers, screwdrivers, wrenches and knives. The 10xx series e. Where as Carbon steel contains up to 0. Mild steel contains a similarly low amount of carbon by weight.
The high tensile steel also contains a low measure of carbon, yet it has some extraordinary alloying components with high tensile strength. Now Steeloncall will give the details of applications that mild steel and high tensile strength are used for the construction process. Properties: A significant property of mild steel is that it isn't fragile.
Also, it doesn't readily undergo a tempering process and has impressive quality. Additionally, it is a good electrical conductor. In this manner, we can utilize it in welding. Additionally, it has high malleability because of the low carbon content. Because of its ferromagnetic properties, we can easily magnetize mild steel. Furthermore, this material is suitable for structural purposes. However, compared to low carbon steel, this material has more carbon accordingly is inclined to erosion.
High tensile steel is a kind of mild carbon steel which has a high yield strength and tensile strength. It contains distinctive alloying components so as to build the tensile strength of the steel. These components include chromium, silicon, manganese, nickel, molybdenum and vanadium, which will be used for special purposes like parts making in automobiles, crane ropes etc. Mild steel is a sort of carbon steel which contains 0. The carbon content in high tensile steel is 0.
Strength: Strength of material is the capacity to oppose force, weight or stress.
