Metallurgical characteristics of armour steel welded joints used for combat vehicle construction

open access: yesDefence Technology, 2018
Austenitic stainless steel (ASS) and High nickel steel (HNS) welding consumables are being used for welding Q&T steels, as they have higher solubility for hydrogen in austenitic phase, to avoid hydrogen induced cracking (HIC) but they are very expensive.
