It has been found that higher yield strength stainless steel 410 is generally more susceptible to sulfide stress cracking, but complicating factor such as microstructure can have significant effect in this susceptibility too.

The purpose of this paper is to demonstrate that heat treatment has an important effect on the ability of stainless steel 410 to resist SSC.

Previous studies of SSC of stainless steel 410 have focused on improper tempering of this alloy; this paper shows how stainless steel 410, which NACE MR0175 lists as resistant to cracking in sour service, failed due to improper heat treatment. i.e. improper heat treatment has produced annealed material which failed in sour service.
