How To Choose M2 Hss Steel For Your Tooling Workshop Specs Stock Sizes And Tips - China

M2 HSS steel is the classic 6-5-2 tungsten-molybdenum high speed steel that workshops around the world still rely on for general purpose cutting tools.

If you are planning to buy M2 HSS steel for drills, end mills, threading taps, reamers, saw blades or cold forming dies, this short buying guide will help you order the right condition and size the first time.

What to check before ordering M2 HSS steel:

1 - Delivery condition.

Spheroidized annealed condition (hardness max 255 HB) is the standard for machining.

If you need ready-to-harden material, ask for pre-hardened or freshly forged-laminated bar with UT certificate.

2 - Size tolerance.

Round bar is normally supplied peeled or turned to h9/h10 tolerance; flat bar and plate can be supplied rough machined or ground.

Confirm widths and lengths (usually 3-6 meter bars or cut-to-size blanks) to reduce your waste.

3 - Certification.

A reliable mill should provide EN 10204 3.1 material certificates showing chemical composition, annealed hardness and grain size.

Third party inspection such as SGS or TUV can be arranged before shipment.

4 - Surface quality.

Look for a fine, uniform carbide distribution without network carbides.

Good M2 HSS steel shows compressive dendritic structure after ESR remelting, which gives better grindability and longer tool life.

5 - Equivalent grades.

M2 HSS steel equals DIN 1.3343 (W-Nr), JIS SKH51 and GB W6Mo5Cr4V2 - Cross-checking these designations helps you compare quotes from different regions.

Recommended heat treatment for M2 HSS steel:

- Preheat slowly at 800-850°C, then harden in neutral salt or vacuum furnace at 1200-1230°C.

- Quench in salt bath, air or vacuum, then triple temper at 540-570°C, 2 hours each time.

- Final working hardness: 62-65 HRC with excellent red hardness up to 600°C.

Our stock covers M2 HSS steel round bar from small dia meter for nib production up to 300mm forged bars, plus flat bar, sheet and saw blade strip.

Custom sizes and cut-to-length blanks are available with fast delivery.
