Description
904L Stainless Steel Seamless Pipe
Pipe Profile
904L super austenitic stainless steel low carbon high nickel, molybdenum austenitic acid resistant steel, excellent corrosion resistance. Since the carbon content is very low (maximum 0.020%), there is no carbide analysis in the case of general heat treatment and welding, which eliminates the risk of intergranular corrosion after general heat treatment and welding.
