... for handling hot, concentrated sulfuric acid. Phosphoric acid is handled by high-molybdenum grades, such as alloy 28 (N08028), G-30 (N06030), and 3127hMo (N08031). Nitric acid at most concentrations and temperatures can be handled by less highly alloyed stainless steels, such as type 304L (S30403), although...

.... Sulfuric Acid Stainless steels require more than a minimum amount of alloying to resist sulfuric acid. Straight 16% chromium grades such as 430 fare poorly, while the nickel-containing 304 has more than an order of magnitude better corrosion rate in either dilute or concentrated sulfuric acid...

... with moisture forms sulfurous acid (H 2 SO 3 ) as well, but as it is a much weaker acid, it does not pose any corrosion problems. At certain temperatures, these vapors condense as a concentrated solution of sulfurous and sulfuric acid on cooler surfaces of the tubes, and hence this process is termed cold...
