Corrosion resistance of 904L stainless steel plate

904L stainless steel plate belongs to (N08904,,14539) super austenitic stainless steel, containing 14.0-18.0% chromium, 24.0-26.0% nickel, and 4.5% molybdenum. 904L stainless steel plate is a low-carbon, high-nickel, molybdenum austenitic stainless and acid-resistant steel.

904L stainless steel plate has good activation-passivation transformation ability, excellent corrosion resistance, good corrosion resistance in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid, and has good corrosion resistance in neutral chloride-containing media. Very good resistance to pitting corrosion.

At the same time, 904L stainless steel plate has good crevice corrosion resistance and stress corrosion resistance. 904L stainless steel plate is suitable for various concentrations of sulfuric acid below 70°C. It is resistant to acetic acid at any concentration and temperature under normal pressure, and the corrosion resistance in the mixed acid of formic acid and acetic acid is also very good.
