 (3)Heat treatment: quenching, annealing, tempering. Quenching temperature: 820℃~870℃, tempering temperature: 550℃~650℃. The ductility is reduced and the quenching is easy to deform and crack. Therefore, heat treatment is extremely important and must be cold after tempering so as to avoid the temper brittleness. The cutting performance can be improved by spheroidzing the steel.
(4) It is widely used in plastic moulds , die frames, mortise pin and guide pillars. If you need certain surface hardness and desire for superior mechanical properties, we can supply the necessary surface hardness  with the carburizing and the quenching.
(5) Processing items: air hammer, ring rolling machine, grinding ring machine and the robot groove machine
