15-5PH Stainless Steel for Laser Powder Bed Fusion (PBF-LB) or Directed Energy Deposition (DED)

Alternative and trade names
MetcoAdd™ 15-5PH-A, MetcoAdd™ 15-5PH-B


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

MetcoAdd™ 15-5PH-A and 15-5PH-B are martensitic, precipitation-hardening stainless steel alloy products with chemistry similar to AMS 5659. 

Room temperature static properties of PBF-LB processed and heat treated material coupons have been shown to be comparable to those of AMS 5659 in the H900 state. 

For reference purposes Oerlikon has processed MetcoAdd 15-5PH-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.
