Scc vs hic
WebHydrogen Induced Cracking (HIC) is a common form of wet H 2 S damage caused by the initiation and propagation of small crack-like flaws, often resembling small internal voids or blisters, that are generally laminar (in-plane) and oriented parallel to the inside and outside surfaces of steel. HIC usually occurs due to the effects of aqueous hydrogen diffusing … WebDec 20, 2024 · Hydrogen-induced cracking (HIC) is also known as: Cold cracking, because it occurs when the metal has cooled below 150°C. Delayed cracking, because its formation is sometimes delayed for 20 hours or more, Underbead cracking, because in most cases it is located at the HAZ underneath the weld bead. Hydrogen Embrittlement.
