Cold work tool steel; oil hardening,high carbon/chromium tool steel with very high wear resistance. It hardens with a very slight change in size. The alloy possesses very high compressive strength and is deep hardening.
Enduse =cutting tools, stamping, woodworking, drawing, deep drawing and pressing tools, cold working rolls, measuring tools.
