The sulfide stress cracking (SSC) resistance of carbon steels and other alloys is commonly addressed through testing according to NACE TM01771 or NACE TM03162. The Method A of the first standard is focused on tests using uniaxial tensile (UT) while the second standard considers 4-point bend (4PB) type of loads. A common way of qualifying a material according to these standards is the absence of failure of the specimens or SSC crack initiation at the surface of the material after a test duration of 720 hours (1 month). After testing, cross-sectional observations of non-broken specimens often reveal so-called “grooves” that can be significantly different in shape and depth depending on the test method, steel grade or environment considered.
