SS 310, also an austenitic stainless steel, is specifically designed for elevated temperature applications, with oxidation resistance extending up to 1100°C. Its high chromium content and standard nickel make it resistant to sulfidation, suitable for applications involving thermal cycling, oxidizing, and nitriding. SS 310S, with a lower carbon content, facilitates easier production processes.
