This paper summarizes the results of electrochemical and SSC tests that were undertaken
to assess the role of chloride content when combined with PH2S and pH in environments
where SSC is likely to occur. NACE Uniaxial Tensile tests were performed according
Fitness-For-Purpose approach recommended in the new edition of NACE MR0175/
15156. The influence of the three parameters led to the creation of a three-dimensional
mapping of SSC susceptibility on the whole range of yield strength. This mapping
the definition of usage domains for Super 13% Cr stainless steel in sour service.
