| 1 | Intergranular corrosion denotes deterioration of metals by means of preferential attacking of the grain boundaries. For austenitic stainless steels, which may be subject to such as attack when they are kept at a temperature between about 430 ºC to 820 ºC, it is associated with the precipitation of chromium rich carbides or intermetallic compounds, such as sigma phase at grain boundaries. The heat cycle, which may provoke sensitization to intergranular corrosion, may occur during hot-forming process like forging and rolling, as the result of incorrect solution treatment or during a welding operation. | |
