Cold work tool steel;oil hardening tool steel.It is relatively inexpensive containing small amounts of manganese,
tungsten and chromium. Hardening by oil quench minimizes distortion and cracking.
Enduse = blanking dies,cold forming dies and cutting tools operating at ambient temperature.For working tools, cutting blades,sizing and stamping tools.
