EOS StainlessSteel 316L
The parts built from 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.
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.
This material is ideal in:
- Lifestyle/Consumer - watches, other jewellery, 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
Layer thickness: 20 µm
Typical achievable part accuracy:
small parts ± 20-50 µm
large parts ± 0.2%
