What is a Cold Cracking? - Definition from Corrosionpedia

Oct 24,2013 prevent cracking in sph590 steel#0183;Cold cracking is also called hydrogen-induced cracking or simply hydrogen cracking because hydrogen trapped in the weld and heat-affected zone is responsible for this type of cracking.This occurs when steel is rapidly cooled and allowed to form martensite.What Causes Stress Corrosion Cracking In Pipelines?Mar 06,2014 prevent cracking in sph590 steel#0183;Stress corrosion cracking (SCC) is a type of environmentally-assisted cracking (EAC),or the formation of cracks caused by various factors combined with the environment surrounding the pipeline.SCC occurs as a result of a combination between corrosion and tensile stress.Corrosion is related to the susceptibility of the material to the environment,while stresses may be residual,Stress Corrosion Cracking of Steel in Liquefied Ammonia Stress-corrosion cracking of steel in liquefied ammonia is traced from its early recognition in the 1950s,from experiences in agricultural and industrial use from NACE (National Association of Corrosion Engineers) recommended DOT (Department of Transportation) regulations to prevent damage,and from laboratory studies to explain the factors
