"COLD WORK TOOLS STEELS" contains a small amount (2~3%) of carbon-silicon, manganese, nickel, chromium, tungsten, vanadium, etc. The alloying elements are also available for various properties by forming a carbide. Silicon, manganese, nickel is an enhanced action, and chromium, molybdenum, tungsten, vanadium, etc. is mainly bonded with carbon to improve wear resistance by forming a carbide.

Strutual carbon is mainly used for structural components of automobiles and various industrial machines.
The most commonly produced items of special steel is divided into carbon steel for machine structual use and Machine
structual alloy steel.
Carbon steel for machine structural use that is up to about 0.6%, of carbon and containing contains only a small amount
of silicon and manganese. is for machine structural component.
Machine structural alloy steel is the same use with carbon steel for machine structual use, but Machine structual alloy steel contains 0.5% of carbon and the addition of one or two more kinds of alloy elements to improve the properties of carbon.
