904L stainless steel pipe


904L stainless steel pipe  (super austenitic stainless steel) is a high alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is specially designed for environments with severe corrosion conditions. It has high chromium content and sufficient nickel content. The addition of copper makes it have strong acid resistance, especially high resistance to chloride interstitial corrosion and stress corrosion cracking. It is not easy to appear corrosion spots and cracks. Its pitting resistance is slightly better than that of other steels. It has good processability and weldability, and can be used for pressure vessels.
