Chuyên Đề Thử ăn mòn ASTM G48- Standard Test Methods for Pitting and Crevice Corrosion Resistance of Stainless

These test methods cover procedures for the determina-tion of the resistance of stainless steels and related alloys to pitting and crevice corrosion (see Terminology G15) when exposed to oxidizing chloride environments. Six procedures are described and identified as Methods A, B, C, D, E, and F.
Method A—Ferric chloride pitting test.
Method B—Ferric chloride crevice test.
Method C—Critical pitting temperature test for
nickel-base and chromium-bearing alloys.
Method D—Critical crevice temperature test for
nickel-base and chromium-bearing alloys.
Method E—Critical pitting temperature test for stain-less steels.
Method F—Critical crevice temperature test for stain-less steels
