nitric acid 316l compatibility versus 304l

Which Valve for Nitric Acid Service?

Another issue people struggle with concerning nitric acid is whether they should use the low-carbon grades 304L,316L or the cast equivalents CF3 and CF3M.The concern is that nitric acid is a strong oxidizing acid that can cause intergranular corrosionone way to minimize the susceptibility to intergranular corrosion is to use the low Understanding Stainless Steels Corrosion-Resistant Grades 316 and 317 offer resistance to phosphoric acid at most concentrations and sulfuric acid at concentrations below 10 percent.Grade 904 offers resistance to high concentrations of sulfuric acid.Types 304L and 430 offer resistance to nitric acid.UREA 316L - Industeel ArcelorMittalThe UREA 316L grade must be used in the as pickled and passivated conditions.Pickling treatment may be performed with a nitro - hydrofluoric acid bath (10 - 20% HN03 - 1.5 - 5% HF) at room temperature (few hours) or 20 minutes approx.at 60 nitric acid 316l compatibility versus 304l#176;C (140 nitric acid 316l compatibility versus 304l#176;F).10 - 20% H2SO4 - 1.5 - 5% HF pickling bath may also be used.WELDING
