What Is S45C Carbon Steel?
S45C carbon steel is a type of medium-carbon steel, commonly used in mechanical structures. It has a carbon content ranging from 0.42% to 0.48%. With its higher carbon content, S45C carbon steel is harder and has greater wear resistance than lower-carbon steels.
The composition of S45C carbon steel includes carbon (0.42% to 0.48%), silicon (Si) (0.15% to 0.35%), manganese (Mn) (0.6% to 0.9%), phosphorus (P) (less than 0.03%), and sulfur (S) (less than 0.035%).
Renowned for its excellent machinability, S45C carbon steel is a highly circulated carbon steel in the market, offering a versatile material choice.
Uses of S45C Carbon Steel
S45C carbon steel is prized for its affordability, superior machinability, and hardenability through heat treatments like quenching. It’s extensively used in the manufacturing of automotive components, particularly in drivetrains and engines. Additionally, S45C carbon steel is a preferred material for gears and shafts in pumps and compressors, benefiting from its enhanced mechanical properties post heat treatment.
