Uniformity Labs Offers Low Porosity Stainless Steel Powders

Additive manufacturing company Uniformity Labs (Uniformity) makes available its ultra-low porosity 316L and 17-4 PH stainless steel powders, a high throughput feedstock. 

Uniformity Labs' low porosity 316L and 17-4 PH powders exhibit tap densities of up to 85% and melt to produce parts averaging over 99.95% density, according to the company. Uniformity HPS parameters for 316L and 17-4 PH Stainless Steel at 50um and 60um layer thickness, respectively, achieve production build rates faster for typical complex geometry additive parts, according to the company. 

Higher bed and tap densities enable Uniformity powders to deliver improved mechanical properties even at high-speed build rates and thicker layer printing. Uniformity will soon release 60um and 90um parameters that demonstrate more production throughput with comparable mechanical properties, further evidence that no compromises need to be made to adopt L-PBF Metal AM.

316L is austenitic stainless steel that works for applications, such as parts exposed to marine, pharmaceutical, or petrochemical processing, food preparation equipment, medical devices, surgical tooling, and consumer products such as jewelry. It is known for its corrosion resistance, high flexibility, and mechanical properties at extreme temperatures, the company reports.

17-4 PH is martensitic precipitation—hardened stainless steel. It’s known for its corrosion resistance and high strength and hardness levels, especially when heat treated. 17-4 PH can be heat treated to various hardness and toughness levels, allowing users to customize the post-sintering properties of the alloy to suit various applications, such as chemical processing, manufacturing machinery, and food processing.
