HEAT TREATMENT PRACTICE AND HARDNESS
Hot working tenperature ℃ /Starting: 1010~1090
Hot working tenperature ℃ /Starting: 1010~1090
Hot working tenperature ℃ /Ending: 930
Annealing temperature ℃: 870~900
Hardness after annealing ≤HBW: 217~255
Quenching temperature ℃: 980~1020
Cooling medium: Air cooled
Tempering temperature ℃: 200~540
Hardness value after tempered /HRC: 61 ~ 54
MELTING PROCESS
This alloy is generally smelt in electric arc furnace (EAF ) or IFF + VD, LF + Electroslag remelting (ESR). For a purpose of higher quality, it should be smelt via technology of vacuum refining.
