A high-carbon tool steel containing substantial chromium (8.0%) and molybdenum (3.4%) alloying elements, designed to achieve exceptional hardness and wear resistance through heat treatment. This composition—with ~1.78% carbon and significant cobalt addition (~4.66%)—positions it in the premium tool steel family, engineered for applications demanding extreme hardness, dimensional stability, and edge retention under demanding conditions. Compared to conventional tool steels, the molybdenum and chromium combination enhances toughness and corrosion resistance while maintaining the high hardness needed for cutting, forming, and gauging operations.
