* Delivery condition: as rolled.

Improved machinability:
In order to improve its machinability, this steel grade can be supplied upon request with Pb (lead) addition, for example Pb=0,15%÷0,35%

Weldability:
Due to the medium-high carbon content it can be welded with some precautions.

Hardenability:
It has a low hardenability in water or oil; fit for surface hardening that gives this steel grade a high hardness of the hardened shell.
