TP 309S Stainless Steel Sheet & Plate delivers excellent oxidation resistance, lower carbon content, and great weldability. Call today
309S Stainless Steel Sheet & Plate (UNS S30908 / EN 1.4833) from DNYA Stainless Steel is a high-performance austenitic stainless steel alloy engineered for excellent high-temperature strength, oxidation resistance, and weldability. With a low carbon content, 309S minimizes carbide precipitation during welding, enhancing its fabrication reliability while still delivering strong mechanical integrity.
This alloy combines high chromium (22–24 %) and nickel (12–15 %) content to provide superior resistance to oxidation and thermal fatigue in extreme environments. It is ideal for furnace components, heat exchangers, exhaust systems, and chemical processing equipment where materials must perform reliably under elevated temperatures and thermal cycling.
