316L Stainless Steel Tube

Professional Stainless Steel Tube Manufacturers and Suppliers in China

316L stainless steel tube is a low-carbon, molybdenum-bearing austenitic alloy that offers exceptional corrosion resistance and improved mechanical properties. It surpasses 304 and 302 grades in resisting general corrosion, pitting, and crevice corrosion, especially in chloride-rich or acidic environments. With enhanced tensile strength, creep resistance, and formability, it is widely used in the chemical processing, marine, food-grade equipment, pharmaceutical, and heat exchanger industries.

As one of the leading stainless steel tube manufacturers and suppliers in China, we specialize in supplying precision-engineered 316L tubes that meet global standards including ASTM, AISI, EN, DIN, and JIS. We offer full customization on dimensions, tolerances, and surface finishes to suit diverse industrial applications, ensuring premium quality and competitive pricing with global delivery.
