BÖHLER K460 corresponds to the material 1.2510 (100MnCrW4, O1) and has comparable properties to the popular tool steel 1.2842. Additional alloying with tungsten achieves higher resistance to abrasive wear compared to the tool steel 1.2842. BÖHLER K460 offers the advantage of simple heat treatment with low hardening temperatures and single tempering. However, this characteristic tempering behaviour limits the use of advanced coatings. The material has a good hardening response, but only moderate through hardenability. BÖHLER K460 is used for punching and cutting tools, plastic molds, thread cutting tools and machine knives in the wood, paper and recycling industries.
