Austenitic Stainless Steel. For austenitic stainless steel, the cause of intergranular corrosion is precipitation of chromium carbides. At temperature above o C, chromium carbides are completely dissolved in austenitic stainless steel.

However, the steels are slowly cooled to ~ o C, chromium carbides are precipitate at grain. The intergranular corrosion of austenite stainless steels is always explained using the chromium depletion theory, which states that intergranular corrosion is caused by Cr enriched precipitations.

corrosion refer to austenitic steels. Study of inter- granular corrosion in martensitic stainless steels is not in current technical literature.

Intergranular corrosion is a potential problem in. austenitic stainless steel. Afterwards it was stan-dardized in ASTM A for DSS. Corrosion rate is determined by measuring the weight loss of the sample. Another test method of measuring the de-gree of sensitization to intergranular corrosion in-volves electrochemical reactivation of the steel sam-ples as defined in ASTM G This.

These carbides build up next to the weld bead where they cannot diffuse due. Chromium content is one of the major criteria in categorizing austenitic stainless steels and has been observed to significantly change the potentiostatic parameters used in studying pitting corrosion resistance of stainless steels [61, 62].
