Steels with high workability by hardening of the surface layer
Pieces obtained from carburized free-cutting steels, with a low carbon content, can be subjected, after machining, to surface hardening treatments through carburizing or other thermochemical treatments.

10SPb20 - Nr.1.0722
The most widespread carburized free-cutting steel; the addition of silicon guarantees the uniformity of the austenitic grain, while the limited percentage of sulfur allows a successful hardening treatment after carburizing.
