W6mo5cr4v2 Vs M2 Comparison Are They The Same High Speed Steel Grade - China

W6Mo5Cr4V2 vs M2 is a common question from buyers comparing Chinese and American steel standards.

The short answer: they are essentially the same tungsten molybdenum high speed steel, just designated under different national standards.

This article explains the details behind the comparison.

W6Mo5Cr4V2 vs M2 at a glance:

- W6Mo5Cr4V2 is the GB (Chinese national standard) designation

- M2 is the AISI (American) designation

- Both correspond to DIN 1.3343 / S 6-5-2 in Germany and SKH51 in Japan

- Composition ranges overlap: 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% Differences you may notice in practice:

1 - Tolerance bands: Chinese GB and AISI windows are extremely close but not word-for-word identical, so certificates should always be checked against your drawing

2 - Melting practice: EAF+LF+VD is standard in both, but individual mills differ in carbide distribution control

3 - Delivery condition naming: annealed max 255 HB is common to both, though inspection paperwork formats differ

4 - Quality level: premium Chinese producers supplying ESR and forged W6Mo5Cr4V2 fully match imported M2 for tooling work Heat treatment for W6Mo5Cr4V2 vs M2 is identical:

- Hardening: 1210-1230 C, quench in oil, salt bath or vacuum

- Triple tempering at 540-560 C

- Working hardness: 63-65 HRC

- Red hardness maintained up to 600 C Which should you buy, W6Mo5Cr4V2 or M2?

For drills, milling cutters, taps, saw blades and cold work dies, either grade performs the same when properly made.

The real selection factors are mill quality, certificate completeness, price and delivery time rather than the designation itself.
