Stainless steel 310S flanges primarily comprise iron, chromium, nickel, and carbon. This unique mix of elements makes them both sturdy and corrosion resistant. Because of stress corrosion cracking in components exposed to halide conditions, larger quantities of chromium were added to develop a more corrosion resistant grade than 304 grade stainless steel. Including nickel improves its thermal resistance up to 2000°F (1093°C). As a result, stainless steel 310S flanges are considered exceptionally trustworthy since they possess properties not seen in other types of stainless steel. Because of their adaptability to various severe heat conditions, they are frequently used in commercial kitchens and other technical applications with rigorous safety requirements.

Type 310S is a high temperature chromium nickel austenitic stainless steel with strong creep strength and resistance to oxidation at temperatures up to 2000˚F (dry air). Type 310S generates tenacious scales at high temperatures, is resistant to spalling, and outperforms Type 309 in thermal cycling applications. In moderately carburising environments, Type 310 offers strong sulfidation and carburisation resistance. Type 310S is the low carbon variant of Type 310, which is used for simplicity of production because of its superior formability and welderability. Type 310S is nonmagnetic when annealed and cold wrought and has the same corrosion resistance as Type 304/304L.

Types 310 Stainless Steel and 310S are often utilised in high temperature applications. Their high nickel and chromium content provide superior raised temperature strength and oxidation resistance compared to Type 304 SS. Type 310S Stainless Steel is the same as Type 310 but for a reduced carbon concentration, which reduces carbide precipitation and enhances weldability. They are mainly nonmagnetic when annealed but become somewhat magnetic when cold worked.
