309/309S Stainless Steel Plate Description

309 stainless steel is an austenitic stainless steel with elevated chromium and nickel content. It boasts outstanding corrosion resistance in various corrosive media, including acid, alkali, salt, and other solutions, as well as organic solvents. This steel maintains excellent corrosion resistance at high temperatures and exhibits good high-temperature strength and creep properties, making it suitable for prolonged use in high-temperature environments, particularly in high-temperature equipment for aviation, chemical industry, and other fields. Additionally, 309 stainless steel can be formed and welded using various processing methods, offering good processing performance. Furthermore, it is non-magnetic, making it suitable for manufacturing parts and components without magnetic requirements.
