D2 tool steel is semi-stainless because it has a high chromium content. This group of tool steel is essentially plain high carbon steel. APPLICATIONS: Where greater dimensional stability in heat treatment or improved wear resistance is required, tool steels with higher alloy contents, such as A2 or D2 should be considered. Stainless steel is generally split into three basic types: martensitic, ferritic, and austenitic. It features excellent impact and shock resistance and decent resistance to softening at high temperatures. Several grades have additional resistance to corrosion due to added chemical properties such as vanadium. Severe distortion is most likely to occur during liquid quenching, so an alloy should be selected that provides the needed mechanical properties with the least severe quench. Tool steel is typically used in a heat treated condition which provides increased hardness. Special purpose group / Plastic Mold Steel.
