Product Advantage:
Stainless steel seamless pipe Super austenitic stainless steel 904L (00Cr20Ni25Mo4.5Cu, UNS: N08904, EN: 1.4539) is a highly alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is specially designed for Designed for environments with harsh corrosive conditions. It has high chromium content and sufficient nickel content. The addition of copper makes it highly acid-resistant, especially highly resistant to chloride gap corrosion and stress corrosion cracking. It is not prone to corrosion spots and cracks, and is resistant to spots. The corrosion resistance is slightly better than that of other steel types. It has good processability and weldability and can be used for pressure vessels.
