OkeyCarbon-only steels for surface hardening
These carburized steels do not contain particular alloy elements in addition to carbon. They are often tempered in water and are therefore only suitable for the production of pieces with simple shapes and applications that are not demanding, such as some pins and bushings.
The R10Pb type is offered in the version with the addition of lead, which facilitates machining by chip removal.

KV15 R15Pb
Kalite
C15E - Nr.1.1141
Non-alloy carburized steel with slightly more carbon than the previous one. Temperable in water.

C16E
Kalite
C16E - Nr.1.1148 C16R - Nr.1.1208
Unalloyed cementation steel very similar to C15 but with a little more manganese which improves its hardenability

SB4
Kalite
C4C - Nr.1.0303
Steel with a very low carbon content, intended for the cold forming of very deformed and difficult-to-obtain small parts.
Rodacciai Mark
CB10FF
Kalite
C10C - Nr.1.0214
Low carbon steel with a chemical composition specially designed for cold deformation. The pieces obtained are generally subjected to carburization and tempering.
