Hydrogen-Induced Stress Cracking of Swaged Super Duplex Stainless Steel Subsea Components

August 1, 2019 by Mariano Iannuzzi

HISC is the Achilles’ heel of duplex and super duplex stainless steels. In this investigation, we demonstrate the detrimental effects of both cold work (swaging) and anisotropic microstructures on HISC resistance. We believe the findings challenge the validity of the present form of DNV-GL RP F112 as a method to reduce HISC risks.
