DIN C50E/Ck50 steel structure is a kind of high quality medium carbon steel, used by the electric furnace, open hearth or pure oxygen converter process all static steel manufacturing . CK50 steel structure has the characteristics of microstructure uniformity.The steel carbon content (mass fraction, %) of 0.4 or higher, good wear resistance, ductility decreases, quenching distortion and cracking easily, so the quenching is extremely important, must be rapid cooling after tempering, to avoid the temper brittleness.By spheroidizing treatment, can improve the cutting performance of this kind of carbon steel.The C50E/Ck50 steel structure mould steel usually tempering to 19 ~ 22 HRC hardness after use, in order to increase its machinability .
