Sohic cracking
WebCarbon and low-alloy steels in plate form and their welded products may be susceptible to one or more forms of environmental cracking when exposed to wet H 2 S service conditions. These include, for example, (1) sulfide stress cracking (SSC) of hard zones and welds; (2) hydrogen-induced cracking (HIC) in the parent metal; and (3) stress-oriented hydrogen … WebSOHIC can have a greater effect on serviceability than HIC because it effectively reduces load carrying capabilities to a greater degree. The inspection requires characterization of …
