Diamant 14S has a Mn-content of 12-14% which provide the steel with excellent wear resistance. Diamant 14S steel combines good wear resistance properties with excellent cold forming properties. The steel structure achieve its final wear resistance when used in abrasive environment. Mechanical forces on the surface make the top layer on the surface transform to martensite. After some use, the surface hardness increase to levels up to 700HB.
Diamant 14S is often used as wear resistant material in crushers, excavators and general mining industry. The material is also used as drilling protection in security cabinets and safety doors. The steel is also used in civil protection applications e.g. in banks, police buildings, armory, shooting ranges and jails. Other applications are interior of automatic shot-blasting machines.
