Description:
S55C is a kind of high quality carbon structural steel and S55C is a Japanese steel grade. S55C is similar with Chinese material 55# steel. S55C steel is full-killed steel manufactured by the process of electric furnace, open hearth or made in pure oxygen converter. S55C has the characteristics of excellent processability, uniform microstructure. The price for S55C is cheap and it is easy processing,suitable for surface hardening treatment, such as high frequency quenching and flame hardening. The material S55C has good wearing resistance. The status of supply and hardness: 149~192HBS,183~255HBS, 229~285HBS.
