Stainless steel | 1.4021 | AISI 420

The martensitic stainless steel 1.4021 impresses with its high hardness, good wear resistance and moderate corrosion resistance. It can be easily heat-treated, allowing its mechanical properties to be specifically adapted, and offers solid toughness combined with high strength. Due to these properties, 1.4021 is often used in the automotive industry, in mechanical engineering and for components subject to wear, such as shafts, valves or knives. Metal 3D printing using laser powder bed fusion allows complex and resilient components to be manufactured from 1.4021 with high precision, enabling innovative design solutions in demanding areas of application.
