Abstract:
A lead free free-cutting steel is described having the following composition in percent by weight: C 0.85-1.2 Si 0.1-0.6 Mn 0.4-1.2 P max 0.05 S 0.04-0.3 Cr max 2 Ni max 1 Mo max 0.5 Cu max 2 Al max 0.1 B max 0.008 Bi+Se+Te max 0.005 Ti+Nb+Zr+V max 0.2 balance Fe and normally occurring impurities. The steel is mainly intended for small/thin dimensions and/or low cutting speeds during manufacture of a product formed of the steel.
