Effect of carbon on steel
Therefore, the carbon in the steel, the higher the carbon content, the strength and hardness of the steel is higher, but the plasticity and toughness will be reduced; on the contrary, the lower carbon content of steel, the ductility and toughness of high strength and hardness will be reduced.Therefore, the carbon content determines the use of steel: low carbon steel (carbon content < 0.25%), commonly used as extrusion and stamping materials; carbon steel (carbon content < 0.6%), commonly used as mechanical parts; high carbon steel (carbon content > 0.7%), commonly used tools, tool and mould etc..
The formation of solid solution organization, improve the strength of steel, such as ferrite, austenite structure, dissolved in carbon elements;2 carbide structure, can improve the hardness and wear resistance of steel. Such as cementite, that is, Fe3C, carbide structure.
Carbon is the main alloying element of steel material. The main role of carbon in steel:
