310 stainless steel temperature limit

310 SS max service temperature

The maximum service temperature of 310 stainless steel is approximately 1,050°C (1,922°F) for continuous operation and up to 1,100°C (2,012°F) for intermittent exposure. Thanks to its high chromium and nickel content, 310 SS offers excellent oxidation resistance up to 1,150°C, making it ideal for use in furnaces, heat treatment equipment, and high-temperature ducts. However, for applications involving sustained mechanical load, it is best used below 980°C to avoid creep deformation.

What is the heat capacity of 310 SS?

The specific heat capacity of Grade 310 is 0.12 Btu/lb ˚F. Under intermittent service, Grade 310 shows excellent resistance to oxidation up to 1035°. In continuous service, it shows resistance to oxidation up to 1050°C. It is also resistant to sulfidation and carburisation.

What are the differences between 310 stainless steel and 310S  in high temperature use?

In high temperature environments, both 310 stainless steel and 310S stainless steel have excellent oxidation resistance and heat stability, and are suitable for continuous use temperatures up to 1050°C and intermittent use temperatures up to 1100°C.

The main difference between the two is the carbon content: 310 has a higher carbon content (≤0.25%), which is prone to intergranular corrosion after high-temperature welding, while the low-carbon design of 310S (≤0.08%) significantly improves weldability and intergranular corrosion resistance, and is more suitable for high-temperature structural parts that need to be welded or pressurized.

Is 310 better than 316 for high temperature?
SS 310: Designed for high-temperature applications, offering excellent strength and oxidation resistance at elevated temperatures. SS 316: While suitable for moderate temperatures, SS 316 may experience reduced corrosion resistance compared to SS 310 in high-temperature environments.
