W6mo5cr4v2 Vs M2 Premium High Speed Tool Bar Supplier - China

W6Mo5Cr4V2 vs M2 High Speed Steel – What is the difference and how to choose? W6Mo5Cr4V2 and M2 are the same high speed steel grade in practice.

M2 is the AISI/ASTM designation widely used in the USA market, while W6Mo5Cr4V2 is the Chinese GB standard designation for the identical 6% tungsten, 5% molybdenum, 4% chromium, 2% vanadium high speed tool steel.

Equivalent grades also include JIS SKH51 and DIN 1.3343, so buyers in Europe, Japan and the USA are actually purchasing the same world standard M2 material under different names.

Chemical Composition (typical):

- Carbon (C): 0.80–0.90%

- Tungsten (W): 5.50–6.75%

- Molybdenum (Mo): 4.50–5.50%

- Chromium (Cr): 3.80–4.40%

- Vanadium (V): 1.75–2.20%

- Silicon (Si): 0.20–0.45%

- Manganese (Mn): 0.15–0.40% Key Properties:

1 - High hardness: reaching HRC 63–65 after proper heat treatment and quenching.

2 - Excellent wear resistance and red hardness, keeping cutting performance at working temperatures up to 600°C.

3 - Good toughness compared with tungsten-type HSS such as T1, reducing chipping risk during heavy cutting.

4 - Fine carbide distribution after EAF + forging process, ensuring uniform performance.

Typical Applications:

- Twist drills, taps, reamers, end mills, saw blades, broaches

- Lathe cutting tools, milling cutters, countersinks

- Cold forming dies, punches, cold extrusion dies

- Wear parts requiring high hardness and heat resistance Why choose Songshun Steel: We stock M2 / W6Mo5Cr4V2 / SKH51 / 1.3343 round bars, flat bars and plates in various sizes with ultrasonic inspection, black or machined surface, and quick delivery.
