HEAT TREATMENT AND HARDNESS FOR COLD WORK ALLOY TOOL STEEL
Hardness after annealing ≤HBW : 240
Quenching temperature ℃ ±10℃ : 950 ~ 980
Cooling medium: Oi, air
Tempering temperature ℃ ±10℃ :  960 (Austenitizing temperature)
Hardness value after tempering /≥ HRC: 325HB Max.
MELTING PROCESS
This
alloy is generally smelt in electric arc furnace  EAF LF VD / BEF + Electroslag remelting (ESR).
For a purpose of higher quality, it should be smelt via technology of vacuum refining.
