High quality stainless steel powders with excellent corrosion resistance

Stainless Steel Powders

Our stainless steel powders are precision-engineered to deliver outstanding properties including high resistance to corrosion and wear.

Produced using high-pressure water atomization under carefully controlled conditions, we custom-make stainless steel powders to the highest quality in the industry.

Enhanced Corrosion Resistance with Ultra Stainless Steels™

Using advanced technology, our patented Ultra Stainless Steels™ are produced by alloying conventional austenitic compositions with a small amount of tin and copper. This combination of metals results in a marked improvement in corrosion resistance when compared to typical austenitic P/M parts while maintaining mechanical properties.

Our Ultra Stainless Steels™ range includes 303L, 304L, and 316L. Rigorous testing confirms the superior corrosion resistance achieved through our Ultra Stainless P/M Technology.
