How To Choose Jis Skh51 Hss Grade For Cutting Tools And Cold Dies - China

JIS SKH51 HSS – Selection Guide For Cutting Tools, Punches And Cold Die Applications JIS SKH51 HSS is the Japanese-standard tungsten-molybdenum high speed steel that has become the default choice for tool rooms around the world.

Equal to AISI M2, DIN 1.3343 and GB W6Mo5Cr4V2, it combines hot hardness up to 600°C working temperature with good toughness, making it suitable for both cutting tools and cold forming dies.

Why SKH51 HSS fits your application:

- Balanced composition: 6% W / 5% Mo / 4% Cr / 2% V delivers fine carbides and stable response in vacuum or salt bath hardening.

- Hardness after heat treatment: HRC 63–65 with excellent wear resistance and red hardness.

- Good grindability compared with high-vanadium grades, reducing tool manufacturing cost.

- Annealed delivery condition HB max 255, ready for machining.

Application recommendations:

1 - Drills, taps and reamers: ideal for general purpose and high-production machining of medium carbon and alloy steels.

2 - Milling cutters and end mills: performs well for shoulder, slot and profile milling.

3 - Cold punches and stamping dies: the toughness of SKH51 HSS resists chipping better than more brittle high-V grades.

4 - Saw blades and broaches: keeps sharp cutting edges under continuous load.
