Description

Designed for Processing in Laser Powder Bed Fusion (PBF-LB), Electron Beam Powder Bed Fusion (PBF-EB) or Directed Energy Deposition (DED) Systems



MetcoAdd™ 17-4PH is a family of martensitic, precipitation-hardening stainless steel powders with chemistry similar to AMS 5643. 


Room temperature static properties of PBF-LB processed and heat treated material coupons have been shown to be comparable to those of AMS 5643 in the H900 state. 


For reference purposes Oerlikon has processed MetcoAdd 17-4PH-A using fixed parameters and 40 μm layer thickness to provide data below. Additional testing has been performed by an extensive network of consortia and customer partners on a broader range of machine types. Properties may be optimized based on application specific requirements
