310S Stainless Steel: High-Temp Oxidation Resistant Alloy

 

What's key about 310S's chemical composition?​

It contains 24-26% chromium, 19-22% nickel, and carbon ≤0.08%. 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 310 in applications?​

310S is preferred for welded high-temperature parts, as its low carbon prevents intergranular corrosion. 310 suits non-welded components needing slightly higher strength at extreme temperatures.​

 

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.
