Stainless Steel 316L

(SS-316L)

 

Our Stainless Steel 316L Powder corresponds to ASTM F138 Specifications for Bar and Wire for Surgical Implants (UNS S31673). This alloy has excellent corrosion resistance and assures no leachable substances in cytotoxic concentrations.

 

SS-316 exhibits:

  • High hardness and toughness
  • High corrosion resistance
  • High machinability
  • Easily polished

 

Applications include:

  • Plastic injection die-casting molds and Extrusion dies
  • Aerospace (especially the turbine industry)
  • Cutlery and kitchenware
  • Maritime components
  • Spindles and screws
  • Automotive industry
  • General engineering (watch, jewelry, frames, decorations)
  • Entry level material for Laser Sintering Technology
