WebCarbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: The term carbon steel may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels. High carbon steel has many ... Websteels. - plain-carbon steels are essentially alloys of iron and carbon with up to 1.2% carbon. - however, the majority of steels contain less than 0.5% carbon. - most steels are made by oxidizing the carbon and other impurities in the pig iron until the carbon content of the iron is reduced to the required level.

The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance. Note that the electrical and thermal conductivity are only slightly altered. As with most strengthening techniques for steel, Young's modulus (elasticity) is unaffected. All treatments of steel trade ductility for increased str…
