W6mo5cr4v2 Chemical Composition Full Element Table For M2 High Speed Steel - China

W6Mo5Cr4V2 chemical composition is defined by the Chinese GB standard and matches the famous AISI M2 grade within extremely narrow ranges.

Understanding each element's role helps buyers evaluate quotations and certificates from different mills.

W6Mo5Cr4V2 Chemical Composition Table (GB/T 9943):

- Carbon (C): 0.80-0.90% - forms hard carbides, basis of wear resistance and hardness

- Silicon (Si): 0.20-0.45% - deoxidizer, supports strength

- Manganese (Mn): 0.15-0.40% - deoxidizer, slight hardenability contribution

- Chromium (Cr): 3.80-4.40% - hardenability, corrosion and oxidation resistance at high temperature

- Molybdenum (Mo): 4.50-5.50% - secondary hardening, red hardness, grain size control

- Tungsten (W): 5.50-6.75% - forms MC and M6C carbides for hot hardness and wear resistance

- Vanadium (V): 1.75-2.20% - hardest MC carbides, wear resistance and grain refinement

- Phosphorus (P): max 0.030% - strictly limited impurity

- Sulphur (S): max 0.030% - strictly limited impurity Why the W6Mo5Cr4V2 chemical composition matters:

- The W-Mo-V balance gives secondary hardening during tempering at 540-560 C

- Chromium ensures full hardenability so large sections harden uniformly

- Vanadium carbides (hardness about 2800 HV) provide cutting edge stability

- Low P and S keep toughness high for interrupted cutting Verification on certificates:

Every heat of W6Mo5Cr4V2 should show spectrochemical analysis results inside these ranges.

Songshun supplies EN 10204 3.1 mill certificates with every order, and third party inspection by SGS, BV or TUV is welcome before shipment.

With correct chemistry and proper heat treatment (hardening 1210-1230 C, triple tempering 540-560 C), this grade reaches 63-65 HRC with red hardness up to 600 C, making it the workhorse for drills, milling cutters, saw blades and cold work dies.
