Molten bismuth stainless steel corrosoion

http://files.aws.org/wj/supplement/WJ_1992_08_s283.pdf WebIntergranular Attack on stainless steel. Intergranular Attack is also a quite rare form of corrosion. If the carbon level in the steel is too high, chromium can combine with carbon to form chromium carbide. This occurs at temperatures between about 450-850 C. This process is also called sensitisation and typically occurs during welding.
