由于许多金属加工部门的竞争日益激烈，因此更加注重缩短交货时间和节省一般成本。与生产长度相关的适当的模具性能在这里至关重要。冷加工工具钢可以设计成抵抗金属加工应用中的各种类型的失效模式。一种具有低摩擦性能的先进工具钢，旨在消除磨损，已被证明是表面涂层工具钢的补充甚至替代品。由于在马氏体基体中引入了特定的硬质相，因此其性能与目前使用的工具钢牌号有着根本的不同。各种金属加工应用的应用测试，如深冲、切削、冷挤压和粉末压制，表明新型低摩擦工具钢的性能显著提高。本文介绍了新合金和不同应用试验的结果。
Owing to an increased competitive situation in many metalworking segments, a more intense focus is directed on lead time reduction and general cost savings. An adequate tooling performance in relation to the production length is of vital importance here. Cold-work tool steels can be designed to resist various types of failure modes in metalworking applications. An advanced tool steel with low-friction properties designed to counteract galling has proven to be a complement or even an alternative to surface-coated tool steels. The properties are fundamentally different to tool steel grades used today owing to a specific hard phase introduced in the martensitic matrix. Application tests from various metalworking applications such as deep drawing, cutting, cold extrusion and powder pressing have shown significant performance increases for the new low-friction tool steel. This paper describes the new alloy and results from different application tests.
