HEAT TREATMENT PRACTICE AND HARDNESS
Annealing temperature /℃: 870 ~ 900
Annealed hardness, ≤ HB: 235 ~ 277
Quenching temperature /℃: 1245 ~ 1275
Cooling medium: oil, air
Tempering temperature /℃: 540 ~ 600
Hardness under tempered condition ≥HRC: 66 ~ 61
MELTING PROCESS
This
alloy is generally smelt in Non-vacuum furnace + ESR, Electric Arc Furnace  (EAF), EAF+LF+VD, LF + ESR.
For a purpose of superior quality, it should be smelt via technology of vacuum refining or by agreement.
