Free-cutting steels carburized
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.
RANGE Free-cutting steels carburized
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.
15SMn13 - Nr.1.0725
Automatic sulfur manganese steel; the limited % of sulfur allows the good treatment of hardening after cementation
