S45C steel is made of pure static steel by electric furnace, open furnace or pure oxygen converter steelmaking process. The steel has uniform microstructure and no organizational defects. The carbon content of the steel is more than 0.4%, and the wear resistance is excellent, but the ductility is reduced.
Chemical composition of S45C die steel
| C | Si | Mn | P |
| 0.42~0.48 | 0.15~0.35 | 0.60~0.90 | ≤0.030 |
| S | Cu | Ni | Cr |
| ≤0.035 | ≤0.30 | ≤0.20 | ≤0.20 |
S45C die steel properties
1, S45C is a kind of high strength carbon high-quality steel, due to poor hardenability, generally used in normalizing state, mechanical properties requirements are higher, the use of tempering treatment.
2, the cold deformation plastic medium, annealing and normalizing of the machinability than the tempering good.
S45C die steel use
1. Used for manufacturing parts with high strength requirements, such as gears, shafts, piston pins, etc., and mechanical workpieces, forgings, stamping parts, bolts, nuts, and pipe joints with small forces.
2, S45C is widely used in mechanical manufacturing, the mechanical properties of this steel is very good. But this is a medium carbon steel, quenching performance is not good, 45 steel can be hardened to HRC42~46. Therefore, if you need surface hardness and want to play the superior mechanical properties of 45# steel, the surface of 45# steel is often carburized and quenched, so that you can get the required surface hardness.
