What Happens to S45C Steel After Hardening?

Before Hardening
The microstructure mainly consists of Ferrite and Pearlite.

 Good toughness and ductility
 Easy to machine and fabricate
Lower hardness and wear resistance

 After Hardening
The microstructure transforms into Martensite.

Significantly increased hardness
 Excellent wear resistance
Extended service life of components
 Increased brittleness, which is why Tempering is often applied to improve toughness and reduce internal stress

With Induction Hardening, only the surface layer is hardened while the core remains tough and ductile. This combination provides superior wear resistance and impact strength, making it ideal for demanding industrial applications.
