Intergranular corrosion test meaning is of metallographic polished sample heat corrosion or electrolytic etching in specific acid solution, then intergranular corrosion and intergranular cracks in the reticular tissue under the microscope and evaluated, and the bending test (90 degrees), surface state, such as gloss, hairline traces and cracks and evaluation.
"Interpretation": stainless steel intergranular corrosion GB/T 21433-2008 in addition to the standard of important content in the standard interpretation, but also on the stainless steel intergranular corrosion concept, formation mechanism, influencing factors and control measures were introduced. The principle and characteristics of the test methods of intergranular corrosion sensitivity, test principle, determine whether the choice of testing methods, sample state determination, evaluation method selection, the qualified index setting, test method of steel plate, the adaptability test scope are analyzed.
