Material Introduction:

A. W6Mo5Cr4V2 (GB) M2( ASTM), S6-5-2(DIN), SKH51(JIS)
chemical composition:C 0.85, Si 0.38, Mn 0.35, P≤0.030, S≤0.030, Cr 4.10, W 6.00, Mo 4.80 V 1.85
main application:It is widely used for making all kinds of cutters and durability cold-work die

B. W6Mo5Cr4V2Co5 (GB), M35( ASTM), 1.3243(DIN), SKH55(JIS)
chemical composition: C 0.93, Si 0.38, Mn 0.35, P≤0.030, S≤0.030, Cr 4.10, W 6.30, Mo 4.80 V 1.85, Co 5.00
main application:It is often used for making blades with high-speed and great cutting difficulty as it’s good abrasive resistance
