CK45 is a kind of super heavy steel for moul.The maximum thickness of CK45 we offer can reach as much as 600 mm.CK45 with the high quality carbon steel,is used by the electric furnace,open hearth or pure oxygen converter process manufacturing full static steel,the steel microstructure uniformity,no tissue defects.
CK45 super heavy steel carbon content over 0.4%,good wear resistance,but the ductility decreases,quenching distortion and cracking easily,so the heat treatment is very important,and must be rapid cooling after tempering,to avoid the temper brittleness.
Based on the steel spheroidizing treatment,can improve the cutting performance of this kind of carbon steel.
CK45 super heavy steel delivery condition:Hot rolled & forging;Black & Machined;Annealing.
