W6mo5cr4v2 Equivalent Grades Chart Aisi M2 Din 1 3343 Jis Skh51 Comparison Guide - China

W6Mo5Cr4V2 equivalent grades are a frequent question from tool makers who source steel from different countries.

W6Mo5Cr4V2 is the Chinese GB standard designation for the most widely used tungsten molybdenum high speed steel, and it has direct equivalents across all major standards.

W6Mo5Cr4V2 Equivalent Grades Table:

- China GB: W6Mo5Cr4V2

- USA AISI/ASTM: M2

- Germany DIN: 1.3343 / S 6-5-2

- Japan JIS: SKH51 (also SKH9 in older practice)

- ISO: HS 6-5-2

- France AFNOR: Z85WDCV 06-05-04-02

- UK BS: BM2

- Korea KS: SKH51

- Russia GOST: R6M5 Chemical Composition (typical, nearly identical across all equivalent grades):

C 0.80-0.90% | W 5.5-6.75% | Mo 4.5-5.5% | Cr 3.8-4.4% | V 1.75-2.2% Because the composition ranges overlap so closely, W6Mo5Cr4V2 equivalent grades deliver the same performance after identical heat treatment:

- Hardening at 1210-1230 C, quenching in oil, salt bath or vacuum

- Triple tempering at 540-560 C

- Working hardness 63-65 HRC with red hardness up to 600 C Are all W6Mo5Cr4V2 equivalent grades truly interchangeable? In most cutting tool and cold die applications, yes.

Small differences may appear in carbide distribution, sulphur level or delivery condition between producers, so buyers working on critical polishing or high volume production should verify mill certificates and test reports before switching suppliers.

Typical Applications for all equivalent grades:

- Twist drills, end mills, taps, reamers and broaches

- Band saw and circular saw blades

- Cold punches, blanking dies and wear parts Songshun supplies W6Mo5Cr4V2 and all its equivalent grades in round bar, flat bar, plate and block, with EN 10204 3.1 certificates, ultrasonic testing and full traceability.
