High speed steel(HSS or HS) is a subset of tool steels,
commonly used in tool bits and cutting tools.
It is often used in power saw blades and drill bits.

| Forging 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. 500-600°C air cooling or furnace cooling HB: 207-255 | |||||||||
| 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. | |||||||||
| Performance Characteristic | Hss M2 has good red-hardness and retains its cutting edge longer than other general purpose high speed steels, not as shock resistant or as flexible as other HSS grades with less tungsten. Generally favored for high production machine work. | ||||||||
| Characteristic Application | used for making tool for lathe,milling cutter,scraper,hobbing cutter,gear wheel cutting,cold work mould and so on | ||||||||
| Packaging | We provide the package according to the export standard (oiled, humidity proofing packing, pallets )or as client's requirements. | ||||||||
| Delivery Time | within 20-30 days after we receive the deposit or L/C at sight. | ||||||||
