This will produce a maximum brinell hardness of 230-300. Stress relieving 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. Hardening Heat up to 450-600oc, then preheat to 850oc, and to 1050oc. Harden from a temperature of 1160-1210oc followed by oil, air quenching or warm bath 550oc. Hardness after quenching is 66-68 hrc. Transformation temperatures: ac1=780oc , ac3=855oc.

High speed steel
High speed tool steel is mainly used for the manufacture of high efficiency. In the annealed state, the main alloying elements in high speed tool steel are tungsten, molybdenum, chromium, vanadium.Because of its high red hardness, good abrasion resistance, high strength characteristics, also used in the manufacture of tool knive and saw blades
