Martensite Chromium Steel
Martensite chromium steel contains a certain amount of carbon in addition to chromium. The chromium content determines the corrosion resistance of the steel, and the higher the carbon content, the higher the strength, hardness and wear resistance. The normal structure of such steel is martensite, and some also contain a small amount of austenite, ferrite or pearlite. Martensite chrome steel is mainly used for the manufacture of parts and components, tools, tools and the like which have high requirements on strength and hardness and which do not require high corrosion resistance. Typical steels of martensitic chrome steel are 2Crl3, 4Crl3, 9Crl8, and the like.
