Intergranular Corrosion Testing Methods and Standards for Clad Layers of Stainless Steel Clad Plates

The current methods of intergranular corrosion testing for the clad layers of stainless steel clad plates in the existing standards and literatures were summarized, and the problems exiting in the intergranular corrosion testing for the clad layers of stainless steel clad plates were analyzed. It was pointed out that the corresponding testing method and the eligibility criteria should be put forward according to the characteristics of stainless steel clad plates, and the current standards for the intergranular corrosion testing for stainless steel clad plates need to be further improved.
