M35 hss

M35 hot rolled high speed steel bar

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.
