The pitting and crevice corrosion resistance of this alloy is shown in Table 8-33. The data show that the alloy has excellent pitting and crevice corrosion resistance in both the as-welded, solid solution and post-weld heat treatment conditions in some pitting and crevice corrosion resistance tests.
