The oil and gas industry has the last few years experienced several major failures in subsea components made of Duplex stainless steel due to Hydrogen Induced Stress Cracking (HISC) with hydrogen introduced from the cathodic protection system. The main objective of the work presented in this paper has been to gain a better understanding of the HISC fracture mechanism. A test method allowing examination of the deformation behaviour in the individual phases during stepwise loading has been developed, and further the deformation in the individual phases have been documented. Both as delivered and hydrogen pre-charged samples revealed that the plastic deformation starts in the austenitic phase (?) while the plastic deformation along slip lines in the ferrite appears to be initiated from dislocation pile ups at the austenite/ferrite phase boundaries. For specimens charged with Hydrogen, HISC took place in the ferrite, most likely initiated as a result of dislocation pile ups in adjacent austenite phases.

Experience has shown that stainless steels can suffer from Hydrogen Induced Stress Cracking (HISC) under cathodic protection in seawater.  This paper presents results from a test program examining the HISC susceptibility of 25% Cr super duplex stainless steel (UNS S32750) at temperatures up to 1500C.
