DIN1.3243 high speed tool steel, high speed steel,high speed steels, Dia: 2-400mm
Application: Heavy-duty milling cutters of all kinds, highly stressed twist drills and taps, profiled cutting blades, machining of high-strength materials, broaches. The Co content of this tough, high-performance, high-speed steel grade, which offers good cutting-edge endurance, results in high red hardness and resistance to tempering. Consequently, this steel grade is particularly suitable when thermal stresses and discontinuous cutting are involved.

High Speed Steel got hardness method: 1. Salt bath hardening or vacuum hardening 2. the temperature 1180-1200°C, if need high hardness add 10°C 3. in the temperature 560°C, tempering more than 3 times. The most important: control hardening temperature and time.
