    316L used in 98% sulfuric acid with chlorides

    316L used in 98% sulfuric acid with chlorides

    Hi all, I would like to know if 316L is suited for the 98% sulfuric acid with chlorides content from 500ppm to 1000ppm, will chloride ion still accelerate the pitting for S.S in 98% sulfuric acid? And what is the corrosion rate versus chloride concentration? many thanks.
