M35 High Speed Steel

M35 high speed tool steel manufacturers and suppliers, supplied in Round Bar,Square Bar,Flat bar,Plate,Sheet and Wire.

M35 is a medium-alloyed high speed tool steel.It is also known as HSSE or HSS-E which is similar to M2, but with 5% cobalt added. The addition of cobalt increases heat resistance. M35 high speed steel also offers excellent cutting performance which is suitable for broaches, taps, milling, reamers, hobs, shapers cutters, saws ,etc.

Heat Treatment
1.M35 is supplied in the annealed and machineable condition.
2.Reannealing will be necessary if the M35 has been hot worked, forged, or hardened.
3.Heat the temperature to 850°C at a rate of no more than 220°C per hour.
4.Hold at the temperature for one hour per inch of thickness(at least two hours).
5.Cool slowly in the furnace or in air to ambient temperature.
6.The resultant hardness achieved should be Max 269HB or lower.
1.Preheat M35 to 450-500°C ,then up to 820-880°C.
2.Heat to the final hardening temperature of 1050-1250°C and make sure the material must be heated through.
3.Quench in the warm oil or brine,and then complete the quench in air.(care must be taken at this step)
1.Tempering must be done immediately after quenching.
2.Heat thoroughly and uniformly to the tempering temperature of 510-620°C.
3.Hold at the temperature for at least two hours (one hour per inch of the total thickness).
4.Triple tempering is strongly recommended for M35 high speed steel.
