17-4PH

Stainless steel powder

Chromium – Nickel – Copper martensitic precipitation-hardening stainless steel with Niobium content. It combines high strength and hardness with good resistance to general corrosion.

The powder is manufactured by Inert Gas Atomization (IGA) with high degree of purity and uniformity. Spherical morphology of particles provides very good flow rate and high packing density.

Other codes: DIN 1.4540, ASTM 630, JIS SU S630, EN 1.4542, ISO X5CrNiCuNb16-4, UNS S17400
