The Forging temperature for high speed steels is 1050°/1150°C. Do not charge direct into the high temperature part of the furnace, but pre-heat slowly to 850°/900. The heat should then be increased more quickly to the forging temperature. If, during the Forging, the temperature of the material drops below 880/900°C, re heating will be necessary. Cool very slowly after Forging.
Annealing:
Annealed at 850°C. Soak thoroughly at this temperature and furnace cool.
Hardening:
Pre heat slowly to 840°C/860°C and thoroughly soak. Continue heating to the final hardening temperature of 1230/1250°C and allow the component to be heated through. Quench in oil or cool in air. Great care must be take not to allow the tools to remain too long at the hardening temperature.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperature and hold for at least two hours (one hour per inch of total thickness). Double tempering of M2 high speed steel is essential with intermediate cooling to room temperature between tempers.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
