EOS StainlessSteel 316L DMSL on EOS M 100
Categories: Metal; 3D Printing/Additive Manufacturing Metal; Ferrous Metal; Stainless Steel

Material Notes: EOS StainlessSteel 316L is a corrosion resistant iron based alloy which has been optimized for processing on EOS DMLS systems. EOS StainlessSteel 316L have chemical composition corresponding to ASTM F138 “Standard Specification for Wrought 18Cr-14Ni-2.5Mo Stainless Steel Bar and Wire for Surgical Implants (UNS S31673). This kind of 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, e.g. watches, other jewelry, spectacle frames, decorations
  • Automotive/Industrial, e.g. non-corroding common material, food and chemical plants
  • Aerospace/Turbine industry
  • Entry-level material for Laser Sintering Technology, e.g. mounting parts, heat exchangers, functional elements in electronic housing and accessories
Parts built from EOS 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.
