This is a high-carbon, chromium-molybdenum tool steel with significant cobalt and nickel additions, designed for applications requiring exceptional hardness and wear resistance combined with controlled toughness. The composition—particularly the elevated carbon content (~1%), high chromium (~9%), and cobalt alloying—positions this steel in the premium tool steel family, likely developed for demanding cutting and forming applications where edge retention and thermal fatigue resistance are critical. This material represents a specialized chemistry that balances the brittleness risk of high-carbon steels against the need for toughness in high-speed or shock-prone service conditions.
