Description

General-purpose, oil-hardened steel suitable for a wide variety of cold working applications. Its main characteristics are good machinability, dimensional stability in heat treatment and the combination of high surface hardness and toughness after heat treatment. It allows the manufacture of tools with good longevity and behaviour.
