Melting Route


Product Description

BÖHLER K245 corresponds to the material 1.2101 (62SiMnCr4). This cold work tool steel is essentially a spring steel optimized for cold work, with very good toughness and spring properties. BÖHLER K245 offers the advantage of simple heat treatment with very low hardening temperatures and single tempering. However, this characteristic tempering behaviour limits the use of advanced coatings. BÖHLER K245 is especially suitable for thin-walled tools such as screwdrivers, hole punches, center punches, ejector pins, punches and cutting tools.
