S55C High carbon steel

JIS S55C is a kind of advanced high-quality medium carbon steel,JIS S55C content (mass fraction, %) of 0.4 or higher,good wear resistance,ductility decreases,quenching distortion and cracking easily,so the quenching is extremely important.

JIS S55C delivery status and hardness:149~192HBS,183~255HBS,229~285HBS.DIA: 80-1200mm(forged round bar),80-1200mm(square bar);Length:3-16 meters.S55C

Heat treatment:Quenching,Annealing,Normalizing and Tempering.
