    China Factory for Stainless Steel Seamless Tube - Stainless steel seamless pipe/tube 201 304 304L 316 316L 310S – Lu

    Introduction Stainless steel seamless steel pipe is a long steel with a hollow section and no joints on the periphery. It is a steel pipe resistant to corrosion by weak corrosive media such as air, steam, water and chemical corrosive media such as acid, alkali and salt. Also known as stainless acid-resistant steel pipe, the corrosion resistance depends on the alloying elements contained in the steel. Chromium is the basic element for the corrosion resistance of stainless steel. When the chrom...
