Compare material type, property direction and particle size together
Compare four stainless steel powders by material family, performance priorities, typical applications and D10, D50 and D90 particle-size data.
17-4PH and 440C
17-4PH focuses on strength, corrosion resistance and heat treatment balance; 440C focuses on high hardness, wear resistance and edge retention.
439 and 17-4+3Cu
439 belongs to the ferrite direction and is suitable for corrosion resistance and thermal cycle; 17-4+3Cu is the project-type material name in Tongcheng's existing data and needs to be confirmed separately according to the target composition, process and performance.
Combining particle size and process selection
The same grade may also be combined with D10, D50, D90, MIM or pressing and sintering process, part structure and final performance selected powders.
