  Super austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu; UNS: N08904; EN: 1.4539) is a high alloy austenitic stainless steel with low carbon content, which 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 gives it strong acid resistance, especially high resistance to chloride interstitial corrosion and stress corrosion cracking. It is not prone to corrosion spots and cracks, and its resistance to pitting corrosion is slightly better than other steel grades. It has good machinability and weldability, and can be used for pressure vessels.
