A high-carbon, cobalt-strengthened tool steel combining significant molybdenum, vanadium, and chromium content to deliver exceptional hardness and wear resistance at elevated temperatures. This composition places it in the family of high-speed steels (HSS) and premium cold-work tool steels, engineered for demanding cutting and forming operations where thermal fatigue and abrasive wear are primary failure modes. The 9% cobalt addition is particularly notable—it boosts heat resistance and toughness compared to standard tool steels, making this grade suitable for applications requiring both hardness retention under temperature cycling and resistance to thermal shock.
