Material Features
- Excellent corrosion resistance
- High strength
- Good ductility
- High wear resistance
- Good machinability
AMPLUS+17-4PH metal powders have been specifically designed and optimised for use in Additive Manufacturing (AM).
AMPLUS+ 17-4PH processes well across the broad spectrum of AM machines and technologies and offers good machinability.
AMPLUS+ 17-4PH is a martensitic precipitation hardening stainless steel, often used for surgical components, tooling, and prototyping.
AMPLUS+ 17-4PH after solution annealing and ageing delivers excellent mechanical properties including high strength and excellent corrosion resistance.
Our Stainless Steel powder is available to purchase in 10kg security sealed containers or alternatively in 50kg drums.
