310S Stainless Steel: High-Temperature Oxidation Resistant Alloy

 

What defines 310S's chemical composition?​

It contains 25% chromium, 20% nickel, and 0.08% maximum carbon. The high chromium and nickel content forms a dense, stable oxide layer, enabling it to resist scaling and oxidation at extremely high temperatures.​

 

How does 310S perform in high-heat settings?​

310S thrives in continuous use up to 1150°C, making it one of the most heat-resistant stainless steels available. It can handle intermittent exposure to 1200°C, suitable for furnace linings, kiln components, and incinerators.​

 

What are its corrosion resistance properties?​

It offers excellent resistance to high-temperature oxidation, sulfidation, and carburization. In room-temperature environments, it resists general corrosion in mild conditions but is less effective in chloride-rich settings than 316.​

 

How does 310S compare to 309S in applications?​

310S is preferred for higher temperature service than 309S, which tops out around 1040°C. 309S is more cost-effective for moderate high-heat applications, while 310S is used when extreme heat resistance is critical.​

 

Where is 310S commonly used?​

Found in furnace parts, heat exchanger tubes, and incinerator linings. It's also used in chemical processing equipment that operates at very high temperatures, such as catalytic crackers and industrial ovens.
