Heat to 850-990oC, cool slowly. This will produce a maximum Brinell hardness of 240-300.
Stress relieving to remove machining stresses should be carried out by heating to 650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
Heat up to 450-500oC, then preheat to 850-900oC. Harden from a temperature of 1140-1180oC followed by inert gas quenching or warm bath 550oC. Hardness after quenching is min. 64 HRC.
Tempering temperature: Min. 3 x 1.5 hour at 560oC.

Milling cutters, broach needles, cutting and punching, tools, dies, working rolls for cluster rolling stand.
High speed steel is a premium cobalt high speed steel with a chemical composition designed for high hardness and superior hot hardness. These properties make the steel an excellent choice for machining high-strength and pre-hardened steels, high-hardness alloys, and the difficult-to-machine, nonferrous super alloys used in the aerospace, oil, and power generation industries.
