Abstract

This International Standard specifies four methods for determination of the susceptibility of nickel-based alloys to intergranular corrosion. These methods are for Iaboratory testing of susceptibility only, and a direct correlation with intergranular corrosion in actual service may not occur unless the service medium is the same as the test medium. The methods covered are as follows: - Method A: iron(lll) sulfate - sulfuric acid test (section 2); - Method B: copper - copper-sulfate - 16% sulfuric acid test (section 3); - Method C: hydrochloric acid test (section 4); - Method D: nitric acid test (section 5); The appropriate melhod for use with a given alloy, the selection of sensitizing treatment, and the acceptance criteria to be used in any evaluation have to be agreed between the buyer and seller of the alloy. As a guide, the methods specified in this in-ternational Standard should be applicable to those nickel-based alloys used for corrosion service and listed in ISO 6207 [1] [1] ISO 6207:-1), Seamless nickel and nickel alloy tube. 1) To be published
