AISI 310 Stainless Steel Chemical Composition & Properties, Grades, Table and Pdf

AISI 310 austenitic stainless steel is a famous material in the high-temperature grades for its high oxidation and sulfidation resistance at temperatures that are above normal. Usually, it contains around 25% chromium and 20% nickel to give it the right hardness along with the addition of elements like manganese and silicon to strengthen its high temperatures properties. AISI 310 is unique in the ability to provide high strength and creep resistance at high temperatures. As the heat treatment component of furnaces or heat treatment baskets, 310 is an ideal choice for various applications in the heat treatment industry. Its grades remain in line with the AISI one, so all the specifications applied to the performance of furniture are observed with presicion. A chart and related PDF describing this alloy's composition, grades, and properties is included together with other material data. It is very handy for engineers to refer to when they are choosing materials or considering designs for high-temperature applications.

AISI 310 Austenitic Stainless Steel Chemical Composition And Grade Table

Alloy AISI 310 is one from the family of austenitic stainless steels that has high temperature resistance and oxidation resistance second to none. Usually its chemical composition is about 25% chromium, 20% niobium, and it also includes a low carbon content. High-grade alloy includes the composition which allows the alloy good resistance to active oxygen, high temperature corrosion at the higher temperature, such as furnace components, heat exchangers, and other high-temperature use. 310 SS has the outstanding creep strength and excellent resistance to sulfidation and carburization. It's highly stable austenitic structure is another advantage of this alloy, which makes it great for industrial applications such as welding and forming.

The Advantages and Disadvantages of AISI 310 Austenitic Stainless Steel


  • High Temperature Resistance: AISI 310 possesses high temperature resistance, giving it a preference in furnace, heat treatment and exhaust systems.

  • Oxidation Resistance: The high chromium and nickel content in AISI 310 make it one of the best resistant materials to oxidation. It ensures it reliability and durability in the most severe environments.

  • Corrosion Resistance: This stainless steel grade is the most corrosion resistant among several high corrosive environments including acid, alkali, and chloride amongst others.

  • Strength and Ductility: AISI 310 has a great combination of strength and durability, resulting in its ability to withstand the effect of mechanical strain and deformation.

  • Weldability: AISI 310 is usually easy to be welded by common welding procedures, which makes the fabrication processes dynamic and less limits creating complicated structures.


  • Cost: In comparison with the other coin stainless steel types, AISI 310 might be a bit more expensive due to its additional nickel and chromium amount, which makes it less competitive for some cases.

  • Sensitization: Under certain conditions, sensitization may occur in AISI 310 steel and result in intergranular in highly corrosive environments if not treated properly or applied within suggested temperature limits.

  • Embrittlement at Elevated Temperatures: AISI 310 does have high-temperature resistance, but its properties can still be diminished if it's being exposed to the temperatures above the recommended operating range for a long time.

  • Thermal Expansion: AISI 310's high coefficient of thermal expansion can cause dimensional variation and deformation in components that face fast temperature cycling. Relevant design considerations should be made.

  • Limited Cold Forming Ability: The low cold formability of AISI 310 is one of its major weaknesses compared to other stainless steel grades which require specialized tools and procedures to form at lower temperatures.
