Skh51 High Speed Tool Steel Trusted In Aviation Nuclear Power And Heavy Equipment Sectors - China

SKH51 High Speed Tool Steel – From Standard Toolrooms To The Most Demanding Industries SKH51 high speed tool steel (JIS G4403, equal to AISI M2, DIN 1.3343 and GB W6Mo5Cr4V2) has earned its place far beyond ordinary machine shops.

With hot hardness up to 600°C, hardness HRC 63–65 after triple tempering at 550–580°C, and a balanced W-Mo-V chemistry (W 5.50–6.75 / Mo 4.50–5.50 / Cr 3.80–4.40 / V 1.75–2.20 / C 0.80–0.90), it serves industries where tool failure is not an option.

Where SKH51 high speed tool steel is specified:

1 - Military industry: machining of armor components and precision weapon parts where tool reliability under long production runs matters.

2 - Nuclear power: valve components, pump shafts and wear parts machined with SKH51 cutting tools; dies for fuel-assembly hardware.

3 - Aviation: turbine fastener tooling, high-temperature alloy machining cutters, and precision gauges for airframe components.

4 - Marine engineering: corrosion-resistant fastener production, propeller machining tools, and dies for seawater-exposed hardware.

5 - Oil exploration: thread-cutting tools and punches for API couplings and drilling equipment components.

6 - Construction and heavy equipment: high-volume stamping and forming dies for structural fittings and wear plates.

What industrial buyers get from Songshun:

- In-house production: EAF refined, 7000-ton press forged, fully annealed (HB 255 max) — not trader stock.

- Complete documentation: mill certificate with heat chemistry, UT reports on sections above 50mm, SGS/BV inspection on request.

- Full size program: round bar dia 3–300mm, flat bar, plate 5–300mm thick, cut blocks per drawing.

- Fast response: common sizes ex-stock dispatched within 48 hours; custom forging 15–25 days.

Quality control you can audit: heat-number traceability on every bundle, hardness verification per batch, and live loading supervision by video call for export orders — the same discipline whether the shipment serves a local job shop or a national energy program.
