Resistance of austenitic SS 316L Sheet to pitting and/or crevice corrosion in the presence of chloride or other halide ions is enhanced by higher chromium (Cr), molybdenum (Mo), and nitrogen (N) content. A relative measure of pitting resistance is given by the PREN (Pitting Resistance Equivalent, including Nitrogen) calculation, where PRE = Cr+3.3Mo+16N. The PREN of Alloys ss 316 sheet and SS 316L Sheet (24.2) is better than that of Alloy 304 (PREN = 19.0), reflecting the better pitting resistance which SS 316L Sheet (or 316) offers due to its Mo content. Alloy 317L, with 31.% Mo and PREN = 29.7, offers even better resistance to pitting than the 316 alloys.
