Sx309 is a highly alloyed austenitic stainless steel with excellent oxidation resistance, high temperature strength and creep resistance.The lower nickel content improves the high-temperature sulfur corrosion resistance of SX309. It is ductile, malleable, easy to manufacture and process. The SX 309S is a low-carbon version of the SX 309, it is recommended for applications where sensitization, subsequent high-temperature gas corrosion, or condensation may occur during shutdown.
Jianglin stainless steel is a renowned manufacturer and supplier of 309 stainless steel tubes that of high quality and various demands including shapes, sizes and dimensions. 309 stainless steel belongs to austenitic range and contains the elements of chromium and nickel. The excellent oxidation resistance and professional along with its high tensile strength and creep strength can be exhibited at the a high temperature condition. This grade of stainless steel tube offers higher resistance for marine environment, which are also equipped with excellent machinability.
Advantages of 309 stainless steel tube are heat resistance, formability and weldability. The tensile strength and process-ability as well as formability and weldability of 309 stainless steel tube make it outstanding among others. The weldability allows 309 stainless steel tube to be welded with convenient welding methods.
Typical application of 309 stainless steel tube can be find in chemical equipment, boiler baffles, furnace components, oven linings, fire box sheets, and many other high temperature containers. The heat treatment triggers no reaction for these tubes, however, the cold treatment can elevate their strength and hardness. By selecting high quality raw material, Jianglin stainless steel only manufactures premium quality stainless steel tubes with our advanced manufacturing technology. With high efficiency, Jianglin Stainless Steel can also manufacture these tubes that satisfies the international quality management.
