More info

Stainless Steel: 17-4PH Spherical Powder

Alternative designation: 1.4542

17-4PH is stainless steel with high yield strength, high wear resistance as well as good corrosion resistance. It is possible to be used in low temperatures and has excellent impact strength even at minus temperatures. Due to the combination of corrosion resistance and good mechanical properties, this material 17-4PH is also suitable for use in maritime environments, whenever the corrosion resistance and mechanical properties of martensitic steels are insufficient. Standing seawater is vulnerable to corrosion fissures. 17-4PH is used in plant construction, the chemical industry, the wood industry, offshore, shipbuilding, mechanical engineering, the oil industry, the paper industry, air, and water industry. space travel, sports, and leisure industry.

Stainless Steel Spherical Powder Production

We developed a unique powder production process to provide perfect spherical powders (patent pending). Any metal or alloy can be atomized according to your needs. Our processes are run with Argon as atomization gas in a dust-free production environment to guarantee maximum product quality. Any process (production, classifying, screening, packaging) can be done under Argon 5.0, so oxygen-free production can be guaranteed. 

Stainless Steel Spherical Powder Screening

With various screening technologies (Cucciolini, Russel-Finex, Kellner) we can screen your powder at grain sizes from 10 to 1000 microns. 

Stainless Steel Spherical Powder Classifying

With our state-of-the-art classifiers (Noll) we can provide narrow particle size distributions, produce ultrafine powders (d99<5 microns), or remove dust from your powders. 

Stainless Steel Spherical Powder Packaging

Stainless Steel 17-4PH Spherical Powder should be stored in a sealed container in a dry and cool place, and should not be exposed to air for an extended period of time. We offer vacuum-sealed packaging including 100g/bag, 500g/bag, 1kg/bag, and 25kg/drum, or we can offer customized packaging as per specific requirements.
