Ultra Metal Powders

This high-quality stainless steel powder, alloy AISI 316L, is engineered for high-velocity oxy-fuel (HVOF) and other thermal-spraying techniques. With a tightly controlled particle-size distribution of 20–53 µm and a spheroidal morphology, the powder ensures smooth feeding, consistent acceleration, and dense, defect-free coating structures.

The high-purity, chemically homogeneous AISI 316L composition delivers excellent corrosion resistance, mechanical robustness, and reliable performance in aggressive environments. The powder is ideal for protective and functional coatings on steel, copper‐alloy and other substrates.

Key facts:

  • Spheroidal morphology – ensures consistent powder flow, predictable spray pattern and efficient deposition

  • Minimal satellites or agglomerates – reduced risk of clogging or overspray

  • High apparent density (min. 3.5 g/ccm)  – supports rapid, dense coating build‐up

  • Chemically homogeneous, high-purity 316L stainless steel alloy

Powder designed for:

  • HVOF (High-Velocity Oxy-Fuel) and other high‐velocity thermal‐spraying processes – for dense, low‐porosity coatings with strong adhesion

  • HVAF & alternative spray technologies – for improved oxidation control and refined surface finish

  • Corrosion‐resistant coatings in harsh environments, functional coatings requiring mechanical strength, thermal stability, or chemical durability
