Astm M2 Cutting Tool Steel Stock Program For Drill Taps And End Mill Makers - China

ASTM M2 cutting tool steel is the reference grade behind most twist drills, threading taps, reamers, end mills and saw blades produced worldwide.

Tool manufacturers choose it because it balances hot hardness, wear resistance and grindability at a price far below cobalt and powder metallurgy grades, and our stock program is built specifically around the needs of cutting tool factories.

Composition per ASTM A600 for ASTM M2 cutting tool steel:

- Carbon 0.78-0.88 percent, controlling primary carbide volume and secondary hardness

- Molybdenum 4.50-5.50 percent together with tungsten 5.50-6.75 percent forming the M6C carbide network

- Chromium 3.75-4.50 percent for hardenability and oxidation resistance

- Vanadium 1.75-2.20 percent for MC carbides that keep the cutting edge sharp Why cutting tool makers prefer our ASTM M2 cutting tool steel:

1 - Consistent annealed max 255 HB with spheroidized microstructure, so your machines see identical stock every month

2 - Carbide distribution rated per SEP 1520 picture series, ensuring strong drill flutes and tap edges without chipping

3 - ESR remelted option for premium end mills where polishability in the flute is required

4 - Full traceability with EN 10204 3.1 certificates matching your ASTM A600 drawing calls

5 - Small trial lots and sample bars for new tool designs before serial production Heat treatment recipe proven in hundreds of tool shops:

- Staged preheat 450 then 850 degrees

- Harden 1200-1220 degrees in vacuum or neutral salt, quench in gas, oil or salt

- Triple temper 555-565 degrees, two hours per cycle

- Result: 63-65 HRC with red hardness stable near 600 degrees, ideal for dry cutting operations and PVD coated tools Sizes kept ready for immediate shipment:

- Round bar 2mm to 300mm for drill rod, taps and reamers

- Flat bar and strip for saw blade backs and broach bodies

- Peeled and centerless ground bar for CNC feed stock

- Cut blanks per your cutting plan with saw tolerance marks on each piece Equivalent standards we ship against: DIN 1.3343, JIS SKH51, HS6-5-2, GB W6Mo5Cr4V2, all certified mill-direct with grade stamps and heat numbers on every bar.

Our engineers also assist with grindability tuning and coating supplier recommendations when you launch a new tool series.
