High Carbon Alloy Steel

Forged High Strength S45C / C45 High Carbon Alloy Steel Round Bar S45C high carbon alloy steel S45C steel is made of electric furnace, open hearth furnace or pure oxygen converter made of all-steel, the steel microstructure uniform, no defects. Chemical Composition(%) C Mn P S 0.48-0.55 0.60-0.90 ≤0.040 ≤0.050 Feature The carbon content of more than 0.4%, excellent wear resistance, but ductility decreases, deformation and cracking easily quenching, so the heat treatment is
