ANALYSIS ON CORROSION FAILURES OF 316L STAINLESS STEEL AND PREVENTION METHODS
|
Abstract:
An analysis was conducted on corrosion failure of 316L stainless steel flange in benzoic acid by diverse laboratory examinations.It has been found that intergranular corrosion caused by the joint of stainless steel is the immanent cause of corrosion failure of 316L stainless steel flange.Besides,the difference between jointing materials and base metal can give rise to dissimilar metal corrosion,so do the use of conductive material-plumbago served as a padding.The crevice between stainless steel flanges can cause crevice corrosion.Some pertinent preventive methods are put forward to on the basis of the analysis of corrosion failure and simulated tests in laboratory.
