HIGH SPEED STEEL Performance FOR HSS-M2AL

 HSS CODE: W6Mo5Cr4V2AL (M2AL) 

 Chemical compositons(%):  

 C                   Si                   Mn               W                  Mo             Cr                        V                     Others   

1.05-1.20   0.20-0.55      0.15-0.40      5.50-6.75     4.50-5.50   3.80-4.40        1.75-2.20              AL:0.80-1.20

 International Code:   

ASTM:   

UNS:  

JIS: 

DIN:  

BS: 

 NF:   

ROCT:  

 ISO:   

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.
