Material Description
1.4034 (X46Cr13 / AISI 420C) is a high-carbon martensitic stainless steel with good corrosion resistance, high hardenability and wear resistance. It is commonly used for knives, surgical instruments, cutting tools, bearings and mechanical components. In the quenched and tempered condition, with a typical tensile strength of approximately up to 30HRC, its machining behavior is similar to conventional high-strength steels. Universal carbide tools designed for medium- to high-strength steels are recommended for roughing, while sharper stainless-steel geometries can also be suitable for finishing. Due to its relatively good thermal conductivity, higher cutting speeds can generally be used compared to austenitic stainless steels of similar strength. For improved tool life, more wear-resistant cutting tools and coatings designed for high-strength steels can be beneficial.
