309/309S Stainless Steel Coil

309 stainless steel is a stainless steel material with excellent corrosion resistance and high temperature performance. It is commonly put into use in aviation, chemical industry, petroleum, food and other fields.
Product Description

309 stainless steel is an austenitic stainless steel comprised of higher chromium and nickel content. 309 stainless steel coil has excellent corrosion resistance in various corrosive media, such as acid, alkali, salt and other solutions, as well as organic solvents. It can still hold up good corrosion resistance at high temperatures. Moreover, it has good high-temperature strength and creep properties and can work stably for a long time in high-temperature environments. It is ideal for high-temperature equipment in aviation, chemical industry and other fields. 309 stainless steel coil can be formed and welded through various processing methods and has good processing performance. Lastly, 309 stainless steel is non-magnetic and works for manufacturing parts and components without magnetic requirements.
