China:M2AL
Density: Annealed(g/cm): 8.11
Heat treatment:Starting: 1100 Finishing:900
Usage:For making all kinds of Broching, Endmills,Planner Blades,etc cutting tools.Cutters working time longer.When cutting tough materials,its working life close to HSS Co life time.
Anneal temperature (℃) 840-860
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.
