Product Overview

Our SUS309S Stainless Steel Seamless Pipe, also known as 1.4828 (X15CrNiSi20-12) and GB grade 06Cr23Ni13, is a heat-resistant austenitic stainless steel seamless tube. Manufactured by hot piercing and cold drawing processes without welding seams, it eliminates the risk of weld line failure under high-temperature service. With high chromium and nickel content plus silicon addition, SUS309S provides strong resistance to high-temperature oxidation and scaling. It can withstand long-term operation at high temperature environments, widely used for high-temperature flue piping, furnace components, heat treatment equipment, boiler pipelines and industrial thermal system piping. We supply full OD and wall thickness specifications of SUS309S seamless pipe to meet your high-temperature industrial project requirements.
