Product Description
309/309S Stainless Steel Pipe Description
309 stainless steel pipe is made of austenitic stainless steel that contains higher chromium and nickel content. 309 stainless steel pipe has excellent corrosion resistance in various corrosive media, including acid, alkali, salt and other solutions, as well as organic solvents. Moreover, it shows good high-temperature strength and creep properties so it can work stably continuously in high-temperature environments. 309 stainless steel pipe can be formed and welded through various processing methods aside from its good processing performance. Lastly, 309 stainless steel is non-magnetic and works for manufacturing parts and components without magnetic requirements.
