Sohic corrosion
WebHydrogen induced cracking (HIC) and the blistering of carbon steel are both such unexpected corrosion phenomenon. Hydrogen damage (Figure 1) is encountered in many steel processes, such as pickling, electroplating and welding. One essential contributing feature of hydrogen damage to welds is that mobile hydrogen, by virtue of its very … WebSOHIC has been reported as the failure mode on at least 12 major pipelines, in addition, numerous reports of SOHIC occurring in pressure vessels are in the literature.
