Super austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) is a high-alloy austenitic stainless steel with low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for harsh corrosive environments. It has a high chromium content and sufficient nickel content. The addition of copper makes it very resistant to acid, especially chloride crevice corrosion and stress corrosion cracking. It is not easy to have pitting and cracks. The pitting resistance is slightly better than other steel grades. It has good machinability and weldability and can be used for pressure vessels.
Brands and standards: UNS N08904 (a standard designed jointly by the American Society of Automotive Engineers and the American Society for Testing and Materials in 1967), DIN1.4539 (German standard), ASTM A240 (American Society for Testing and Materials standard; the new standard classifies it as a stainless steel series, and the original standard ASME SB-625 classifies it as a nickel-based alloy series), SUS890L.
Metallographic structure of 904L stainless steel: 904L is a completely austenitic structure. Compared with austenitic stainless steels with a high molybdenum content, 904L is not sensitive to the precipitation of ferrite and α phase.
904L (N08904, 1.4539) super austenitic stainless steel contains 19.0-20.0% chromium, 24.0-26.0% nickel, and 4.5% molybdenum. 904L super austenitic stainless steel is a low-carbon, high-nickel, molybdenum austenitic stainless acid-resistant steel, which is a proprietary material introduced from the French H.S company. It 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, good pitting resistance in neutral chloride ion media, and good crevice corrosion resistance and stress corrosion resistance. It is suitable for various concentrations of sulfuric acid below 70°C, and has good corrosion resistance in acetic acid of any concentration and any temperature under normal pressure, and mixed acid of formic acid and acetic acid.
Super austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu, N08904, 1.4539) is a high-alloy austenitic stainless steel with low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for harsh corrosive environments. It has a high chromium content and sufficient nickel content. The addition of copper makes it highly resistant to acid, especially chloride crevice corrosion and stress corrosion cracking. It is not easy to have pitting and cracks. The pitting resistance is slightly better than other steel grades. It has good machinability and weldability and can be used for pressure vessels.
