High speed steels

Cutting tools made of High-Speed Steel achieve high hot hardness, wear resistance and fracture resistance at a hardness of over 60 to 67 HRC through hardening and tempering. The main alloying elements are Carbon, Tungsten, Molybdenum, Vanadium and Cobalt. High contents of carbide-forming elements lead to the formation of wear-resistant carbides in the microstructure.
