W6mo5cr4v2 Chemical Composition Analysis With Element Functions - China

W6Mo5Cr4V2 chemical composition is the foundation of its performance as the world standard M2 type high speed steel.

Each alloying element plays a designed role, and mill certificates should always be checked against the standard range before the material enters production.

Standard Chemical Composition (GB/T 9943, AISI M2 equivalent):

- Carbon (C): 0.80-0.90%

- Silicon (Si): 0.20-0.45%

- Manganese (Mn): 0.15-0.40%

- Chromium (Cr): 3.80-4.40%

- Molybdenum (Mo): 4.50-5.50%

- Tungsten (W): 5.50-6.75%

- Vanadium (V): 1.75-2.20%

- Phosphorus (P): max 0.030%

- Sulfur (S): max 0.030% What Each Element Does:

1 - Carbon 0.80-0.90%: forms hard carbides with W, Mo, V; too high makes the steel brittle, too low reduces hardness.

2 - Tungsten 5.50-6.75%: together with molybdenum forms M6C carbides, the base of secondary hardness and red hardness.

3 - Molybdenum 4.50-5.50%: works with tungsten; the W+Mo balance gives better toughness than the old T1 type.

4 - Chromium 3.80-4.40%: improves hardenability so even large sections quench fully; also adds corrosion resistance at high temperature.

5 - Vanadium 1.75-2.20%: forms very hard MC carbides for wear resistance and grain refinement.

6 - Silicon and Manganese: deoxidize the melt and improve the steel cleanliness.

How to Verify Composition on Arrival:

1 - Ask for EN 10204 3.1 mill certificate showing heat analysis.

2 - Check W, Mo, V values are inside the range, not just near the minimum.

3 - Confirm P and S are below 0.030% for better toughness.

4 - For critical tools, request a third-party spectrometer report.

Typical deviation warnings: high carbon plus high vanadium increases grinding difficulty; low molybdenum reduces secondary hardening response; sulfur above the limit causes hot shortness during forging.
