EOS 3D Printed StainlessSteel 316L Processed by DMSL on EOSINTM280
Categories:	Metal; 3D Printing/Additive Manufacturing Metal; Ferrous Metal; Stainless Steel; T 300 Series Stainless Steel
Material Notes:	Description: The parts built from EOS 3D Printed StainlessSteel 316L have chemical composition corresponding to ASTM F138 “Standard Specification for Wrought 18Cr-14Ni-2.5Mo 3D Printed Stainless Steel Bar and Wire for Surgical Implants (UNS S31673)”. This kind of 3D Printed Stainless steel is characterized having a good corrosion resistance and evidence that there are no leachable substances in cytotoxic concentrations. This material is ideal in Lifestyle/Consumer - watches, other jewelry, spectacle frames, decorations, functional elements in electronic housing and accessories Automotive/Industrial – non-corroding common material, food and chemical plants Aerospace/Turbine industry – entry-level material for Laser Sintering Technology, mounting parts, brackets, heat exchangers Parts built from EOS 3D Printed StainlessSteel 316L can be machined, shot-peened and polished in as-built or stress relieved (AMS2759) states if required. Solution annealing is not necessary because the mechanical properties of as-built state are showing desired values (ASTM A403). Parts are not ideal in temperature range 427°C - 816°C where precipitation of chromium carbides occurs. Due to layer-wise building method, the parts have a certain anisotropy which could be seen from mechanical properties. Information provided by Proto3000
