breaking characteristic of calciu carbide steel
Crucible Tool Steel and Specialty Alloy General Information
Hardness of Carbides. Instead, it is intended to combine with other elements in the steel to form hard particles called carbides. Tool steels contain elements such as chromium, molybdenum, tungsten, and vanadium. These elements combine with the excess carbon to form chromium carbides, tungsten carbides, vanadium carbides, etc.
