Description

Designed for Processing in Laser Powder Bed Fusion (PBF-LB) Systems


MetcoAdd™ H11-A is martensitic, iron-chromium, air-hardenable steel powder product with chemistry similar to UNS T20811, ASTM A681, SAE J437, AMS 6487 and Werkstoff No. 1.2343 / X37CrMoV 5-1. 


Room temperature static properties of PBF-LB processed and heat treated material coupons have been shown to be comparable to those of AMS 6487.
