Stress relief Temperature（℃）:600-650  

Quench temperature （℃）:1230-1240  

 Coolant media of quench : salt bath  at 600℃,or Oil  cool or air cool  

Normal temperature of temper（℃）: 540-560   

Quench and temper HRC: 65-67   

Bending Strength(Mpa):    3000-4100

Impact Toughness(MJ/㎡): 0.25-0.30   

HRC at 600℃(HRC):   55-56

Character: Its general used HSS of W-Mo series steel. With High Hardness,wear resistance.High Hardness of high temperature ,High Red Hardness and Good hot forming etc.Its Pressure resistance higher than HSS-Co.But grandability a little inferior,larger Superheated susceptivity, easy for oxide and decarburized.
