Product Overview

Our SUS304 Stainless Steel Seamless Pipe, also known as 1.4301 (X5CrNi18-10) and GB grade 06Cr19Ni10, is the most widely used austenitic stainless steel seamless tube. Manufactured by hot piercing and cold drawing process without welding seam, it eliminates potential weak points from weld lines. This grade balances corrosion resistance, mechanical strength and cost efficiency. It resists oxidation and rust under normal atmospheric, fresh water and weak acid conditions. Available in a full range of outer diameter and wall thickness specifications, our SUS304 seamless pipe is commonly used for water treatment, food sanitary piping, chemical equipment, construction structural piping and general industrial fluid transport.
