This is a high-carbon, high-alloy tool steel formulated with substantial molybdenum, chromium, vanadium, and cobalt additions to achieve exceptional hardness and wear resistance. The composition—particularly the 1.82% carbon, 7.55% chromium, 3.37% molybdenum, and 4.67% cobalt—positions this grade as a premium high-speed or premium cold-work tool steel variant, designed to balance edge retention with toughness for demanding cutting and forming applications. Engineers select this alloy where tool life and dimensional stability under heavy use justify the higher material cost, typical in high-volume production runs, precision stamping, and cutting tool applications requiring resistance to thermal fatigue and abrasive wear.
