Stainless Steel 17-4

Direct Metal Laser Sintering Material

Stainless Steel 17-4 is a pre-alloyed stainless steel in fine powder form. Its composition corresponds to US classification 17-4 and European 1.4542 and fulfils the requirements of AMS 5643 for Mn, Mo, Ni, Si, C, Cr and Cu. This kind of steel is characterized by having very good corrosion resistance and mechanical properties, especially excellent ductility in laser processed state, and is widely used in a variety of engineering applications.


This material is ideal for many part-building applications (Direct Part) such as functional metal prototypes, small series products, individualized products, spare parts, parts requiring high corrosion resistance, sterilisability, high toughness and ductility.
