This is a tool steel in the high-carbon, high-chromium family, alloyed with molybdenum, vanadium, and nickel for enhanced hardness, wear resistance, and toughness—a composition typical of premium die steels and cold-work tool grades. The notably high cobalt content (13.4%) is unusual for conventional tool steels and suggests this may be a specialized or proprietary composition, possibly developed for extreme wear or thermal fatigue resistance in demanding tooling applications. Engineers would select this material for applications requiring excellent edge retention and resistance to thermal cycling, where standard tool steels fall short.
