High speed steel M2/DIN1.3343 manufacture and supplier

Chemical composition table%

AISI M2 high speed steel round bars

To meet end users further processing needs, the material what we provided is without heat-treatment.

Our hss materials sold to foreign and domestic market. We have own plant and have reliable professional supplie
package for bars:
the bars will be oiled for rust protection, - one dia should be packed in one bundle by the steel strip; bundles should be oiled and turned into the PE film then packed in wooden boxes for easy loading.

Tungsten molybdenum high speed steel M2
HSS AISI M2 has a series of advantages, like small carbide and well distributed, higher wear-resistance, and lower cost. the hardness main *7HRC**8 HRC, and ****3 HRC separately under **0°C***0°C. Bending strength can be ***0MPa, the toughness and thermoplasticity can be improved *0% compare with W*8Cr4V, can be used as making different of tools. like drills, screw tap, miller cutter, reamer, knife ect, can be meet normal material request.

Our Services
Provide samples, but need to pay the samples fees, **0RMB/Kg.

M2 is widely used in applications requiring a high degree of toughness; grindability, good wear resistance and high hardness.

Applications include:

-Lathe Tools; Planer Tool; 

-Drills; Taps; Reamers; Broaches;

-Milling Cutters; Thread Cutters; End Mills;

-Blanking Dies; Gear Cutter; Router Bits.

Heat Treatment

Forging:

-Preheat slowly to ***0 F until piece is thoroughly heated through, then increase heat to ***0 F ****0 F.

-DO NOT hot work M2 below ***0 F.

- After forging, allow M2 to cool slowly, packed in lime or other insulating material.( For large forgings, let soak in large furnace at ***0 F, then cool in furnace.)

-Anneal as soon as possible.

Anealing:

-Surface protection-Anneal in controlld atmosphere furnace or pack in an inert material.
-Slowly heat M2 to ********0, cool slowly at a rate of *0 F/ hr until furnace is black. Shut down furnace, allow to cool normally, annealed hardness range is ******0 Brinell.

Stress-relieving:

Temperature ********0 F. Rough machine after stress relieving. Hold tool for 2 hours after reaching full temperature. Cool in furnace to **0 F and then air-cool.

Hardening:

Single-edge cutting tools: ********5 F ( salt bath)
***0 F ****0 F( furnace)

Roating multi-edge cutting tools: ***0 F ****0 F

Punches, dies, etc: ********0 F.

Tempering:

-Temper immediately when piece reaches **0 F or when comfortably hand-held.
-Tempering temperature should be in the range of ***0 F****0 F.
-Heat slowly to temperature, hold tools at heat for 2 hours before air cooling.
-For best toughness, after tool has cooled, retemper for 2 additional hours at slightly lower temperature.
