Introduction
AISI 310S stainless steel plate is a high-temperature austenitic stainless steel grade known for its exceptional resistance to oxidation and good high-temperature strength. This steel belongs to the 300 series and is the low-carbon version of AISI 310. The lower carbon content improves its weldability and reduces the risk of carbide precipitation during welding.
Composition
The key elements in AISI 310S are:
Chromium (24-26%): Provides the foundation for excellent oxidation resistance and high-temperature strength.
Nickel (19-22%): Contributes to good high-temperature strength and maintains austenitic microstructure.
Silicon (0.5% max): Improves oxidation resistance at high temperatures.
Low Carbon (Less than 0.03%): Minimizes the risk of chromium carbide precipitation during welding, enhancing weldability and preventing potential corrosion issues around the weld zone.
Characteristics
Exceptional Oxidation Resistance: AISI 310S offers outstanding resistance to oxidation and scaling at elevated temperatures, making it ideal for applications involving continuous or intermittent exposure to high heat.
Good High-Temperature Strength: Compared to standard austenitic stainless steels, 310S retains good strength and creep resistance at elevated temperatures up to 1050°C (1922°F).
Good Formability: AISI 310S exhibits moderate formability, allowing for some shaping during fabrication. However, due to its higher chromium content, it is generally considered less formable than standard 304 stainless steel.
Improved Weldability: The low carbon content minimizes chromium carbide precipitation, leading to better weldability compared to standard AISI 310. However, proper post-weld heat treatment might be necessary in some applications to maintain optimal corrosion resistance.
Magnetic: Unlike most austenitic stainless steels, AISI 310S is magnetic in all conditions due to its high chromium content.
Uses
Due to its exceptional oxidation resistance, good high-temperature strength, and improved weldability, AISI 310S stainless steel plate finds application in various high-temperature environments, including:
Heat Exchangers: Components exposed to high temperatures in heat exchangers, furnace parts, and afterburners can benefit from the oxidation resistance and high-temperature strength of 310S.
High-Temperature Reactors: Cladding materials, piping, and other components in high-temperature reactors utilize 310S due to its resistance to oxidation and high-temperature performance.
Turbine Components: Certain turbine parts, such as shrouds and casings, can utilize 310S for its high-temperature strength and oxidation resistance.
Cryogenic Applications: Although designed for high temperatures, 310S also exhibits good toughness at cryogenic temperatures, making it suitable for some low-temperature applications.

Additional Points
AISI 310S comes in various standard specifications, such as ASTM A240/ASME SA240. ensuring consistent material properties.
Due to its higher chromium content and focus on high-temperature performance, 310S generally has lower corrosion resistance in aqueous environments compared to standard 304 stainless steel.
When high-temperature strength and oxidation resistance are paramount, but weldability is not a major concern, AISI 310 (with slightly higher carbon content) might be a viable alternative.
