WebJun 17, 2024 · Stress relaxation cracking (SRC), also referred to as stress relief cracking or reheat cracking, is a high-temperature (500-700°C or 932-1292°F) failure mode.It is associated with the welding of thick-walled, highly restrained components of austenitic stainless steel, ferritic stainless steel, heat-resistant steel (Cr-Mo-V) and nickel-base … WebStress Corrosion Cracking (SCC) requires three conditions to occur: applied or residual stresses, an aqueous corrosive media (Chlorides and Hydrogen Sulphide are common), and elevated temperatures. Unlike many forms of corrosion, SCC may not appear visible to the naked eye. This means component failure may come without warning should risk ...

WebSulfide stress cracking (SSC) is a form of hydrogen embrittlement which is a cathodic cracking mechanism. ... At high temperature and high hydrogen partial pressure, hydrogen can diffuse into carbon steel alloys. In susceptible alloys, hydrogen combines with carbon within the alloy and forms methane. The methane molecules create a pressure ... Webprocess, the crack occurs in the base material, not in the weld material. This type of cracking is also known as “underbead cracking,” “toe cracking,” or “delayed crack-ing.” Because this cracking occurs after the steel has cooled below approximately 400°F, it can be called “cold cracking”, and because it is associated with ... WebFeb 8, 2024 · Intergranular corrosion occurs in certain grades of stainless steel when the steel is heated, as with welding. In this case, brittleness results, causing the metal to crack near the weld. For this reason, a post-weld heat treatment is needed before reinstalling stainless steel parts that have been welded.
