BÖHLER K245 corresponds to material 1.2101 (62SiMnCr4). This cold work steel is essentially a spring steel optimized for cold work with very good toughness and spring properties. BÖHLER K245 offers the advantage of a simple heat treatment with very low hardening temperatures and a simple tempering treatment. Due to this tempering behavior, however, the use of modern coatings is only possible to a limited extent. BÖHLER K245 is particularly suitable for thin-walled tools such as screwdrivers, punches, center punches, ejector pins, punches and clamping tools.
