Colibrium Additive Stainless Steel 17-4PH, as-built, is that maker's grade of 17-4PH precipitation-hardening stainless steel made by laser powder bed fusion and not heat treated after the build. Rapid solidification leaves a fine cellular, largely martensitic structure that can hold retained austenite and lacks the copper-rich strengthening precipitates, so its properties differ from aged material and vary with build direction. Parts carry residual stress and a rough surface and need supports. They are normally stress relieved, solution treated and aged, and machined on critical surfaces. Finished parts serve as tooling inserts, pump and valve components, and brackets that need strength with corrosion resistance.

EOS StainlessSteel 17-4PH is the EOS grade of 17-4PH precipitation-hardening stainless steel, supplied as a powder with matched process parameters for laser powder bed fusion. As built, the rapidly solidified material has a fine cellular structure that can retain substantial austenite alongside martensite. Parts are therefore normally solution treated and aged to reach the hardened martensitic condition. Parts are built on supports and carry residual stress, so they are usually stress relieved before removal from the build plate, and surfaces are blasted or machined where finish matters. It is used for functional parts, tooling inserts and components that need high strength with good corrosion resistance.

EOS StainlessSteel 17-4PH in the aged condition is a precipitation-hardening martensitic stainless steel printed by laser powder bed fusion and then aged, usually after a solution anneal. As printed, rapid solidification leaves a fine cellular structure that can retain some austenite, along with residual stress, build-direction anisotropy and rough support-side surfaces. Ageing precipitates copper-rich particles in the martensite, raising strength and hardness. Parts still need support removal and machining or blasting of functional faces. Printed parts serve as tooling inserts, brackets, and pump and valve components that need strength with moderate corrosion resistance.
