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.

This material data has been provided by Oerlikon Metco.

All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
