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.
