This is a high-carbon, high-chromium martensitic stainless steel alloyed with molybdenum, vanadium, and nickel, designed to achieve excellent wear resistance and hardness through precipitation hardening and martensitic transformation. The elevated cobalt content (11.7%) is unusual for conventional tool steels and suggests this material is formulated for specialized high-performance applications requiring superior edge retention, thermal fatigue resistance, or corrosion resistance combined with extreme hardness. Engineers would select this alloy over standard tool steels (like D2 or O1) or conventional stainless steels when cost is secondary to performance in extreme wear or high-temperature corrosive environments.
