Powder stainless steel 316L

aeronauticalfor the aerospace industry

Stainless steel’s material characteristics make it ideal for a wide range of applications in medical, oil and gas, ship building, etc. The stainless steel family of powders encompasses the 316L, 316L VPro, 254, SuperDuplex, 17-4PH, PH1 (15-5) and CX alloys. All these powders are designed and tested for use on EOS’ metal systems. EOS stainless steel powders are shipped with an inspection certificate (according to EN 10204, Type 3.1) showing the results of the extensive QA testing. Only EOS StainlessSteel SuperDuplex is shipped with a material test report (according to EN 10204, Type 2.2) showing the results of the QA testing with regard to the chemical properties and particle size distribution. EOS also offers a wide range of validated processes for each of the above materials. These offer the optimal combination of parameters (e.g. laser power, layer thickness, etc.) in order to ensure that the properties of the 3D printed part are consistently achieved. Parts show a high level of corrosion resistance combined with high strength. This combination is ideal for the medical applications such as surgical instruments. Highlights Corrosion resistance and strength Parts can be machined, shot-peened and polished in asbuilt or heat treated states Solution annealing together with aging treatment are necessary in order to achieve proper hardness and mechanical properties (ASTM A564-13) Chemical composition and part properties corresponding to 1.4542, UNS 17400 and ASTM A564M Typical Applications Acid and corrosion resistant engineering parts Medical instruments (surgical tools, orthopedic instrumentation)
