Cold Drawn Large Diameter Steel Pipe

Cold Drawn Large Diameter Steel Pipe

High Temperature Thin Wall Seamless 904L Stainless Steel Pipe 904L stainless steel pipe(00Cr20Ni25Mo4.5Cu) is a kind of austenitic stainless steel with better corrosion resistance. With the adding of 1.5% Cu, it also has excellent corrosion resistance for reductive acids such as sulfuric acid...

Description

904L stainless steel, also known as super austenitic stainless steel, is a high-alloy austenitic stainless steel with low carbon content. It is very resistant to corrosion in dilute sulfuric acid and is designed for harsh environments. With high chromium content and sufficient nickel content, the addition of copper makes it have strong acid resistance, especially high resistance to chloride crevice corrosion and stress corrosion cracking, and it is not easy to cause plaque and cracks. Excellent corrosion resistance and other steel grades, with good processability and weldability, can be used in pressure vessels.
