Stainless Steel 3D Printing

Stainless steel is a corrosion resistant metal with high hardness and strength

Stainless steel is a corrosion resistance metal with high hardness making it a versatile material option. We offer two grades of stainless steel through our 3D printing service:

Stainless Steel 17-4 PH
Select 17-4 PH for its significantly higher tensile strength and yield strength, but recognize that it has far less elongation at break than 316L. Final parts built 17-4 PH receive vacuum solution heat treatment as well as H900 aging.

Primary Benefits

  • Heat treated for full hardness and strength
  • Corrosion resistance

Stainless Steel 316L
Choose 316L when stainless steel flexibility is needed; 316L is a more malleable material compared to 17-4 PH. Final parts built in 316L receive stress relief application.

Primary Benefits

  • Acid and corrosion resistance
  • High ductility
