Product Description
310S UNS S31008 Hot Rolled Stainless Steel Sheet is a high-temperature austenitic stainless steel designed for demanding applications where heat resistance, oxidation resistance, and long-term structural stability are required. Manufactured from AISI 310S / UNS S31008 stainless steel, the sheet is particularly suitable for industrial furnaces, heat-treatment equipment, high-temperature process systems, and thermal processing equipment.
Why Choose 310S Stainless Steel Sheet?
The main advantage of 310S stainless steel is its ability to perform reliably at elevated temperatures. Its relatively high chromium and nickel content provides excellent resistance to oxidation and scaling compared with many conventional stainless steel grades.
This makes 310S a preferred material for equipment exposed to:
- High operating temperatures
- Thermal cycling
- Oxidizing atmospheres
- Furnace gases
- Heat-treatment processes
- High-temperature industrial environments
Industrial Furnaces
310S hot rolled stainless steel sheet can be used for components and structures in:
- Furnace linings
- Furnace doors
- Furnace panels
- Furnace structural components
- Furnace covers
- High-temperature supports
- Heating equipment components
Heat-Treatment Equipment
The material is also suitable for:
- Heat-treatment furnace components
- Annealing equipment
- Heat-treatment trays
- Heat-resistant containers
- Furnace fixtures
- Thermal processing equipment
Other High-Temperature Applications
- Petrochemical processing equipment
- High-temperature piping and ducts
- Heat exchangers
- Thermal processing systems
- Industrial combustion equipment
- High-temperature structural components
For hot rolled 310S stainless steel sheet, the most common surface condition is:
No.1 / HRAP (Hot Rolled, Annealed and Pickled)
The process generally includes:
Hot Rolling → Annealing → Pickling → Leveling → Inspection → Cutting
The pickling process removes oxide scale generated during hot rolling and heat treatment, producing a clean and uniform industrial surface.

1. What is 310S stainless steel?
310S stainless steel (UNS S31008) is a high-alloy austenitic stainless steel containing approximately 24–26% chromium and 19–22% nickel. It is specifically designed for applications requiring excellent high-temperature and oxidation resistance.
2. Why is 310S suitable for industrial furnaces?
310S provides excellent resistance to oxidation, scaling, and high-temperature degradation, making it suitable for furnace components exposed to elevated temperatures and thermal cycling.
3. What are the main applications of 310S stainless steel sheet?
Typical applications include:
- Industrial furnace panels
- Furnace doors and covers
- Heat-treatment equipment
- Annealing furnace components
- Furnace trays and fixtures
- Heat-resistant supports
- High-temperature ducts
- Petrochemical processing equipment
- Thermal processing systems
4. What is the maximum operating temperature of 310S?
The applicable temperature depends on the atmosphere, load, thermal cycling, and service conditions. 310S is widely used for high-temperature service and can provide excellent oxidation resistance at temperatures around 1000°C in suitable conditions. Engineering design should use temperature-specific data rather than relying on a single maximum temperature.
5. What is the difference between 310S and 304 stainless steel?
310S has significantly higher chromium and nickel contents, giving it much better oxidation resistance and high-temperature performance.
- 310S: High-temperature / furnace applications
- 304: General-purpose corrosion-resistant applications
6. What is the difference between 310S and 316L?
316L is primarily optimized for corrosion resistance, especially in chloride and marine environments, while 310S is optimized for high-temperature and oxidation resistance.
310S → High Temperature
316L → Corrosion & Marine Resistance
7. Is 310S stainless steel corrosion resistant?
Yes. 310S provides good corrosion resistance in many industrial environments. However, its main advantage is high-temperature oxidation resistance, rather than resistance to severe chloride or seawater environments.
8. Is 310S stainless steel magnetic?
310S is generally non-magnetic in the annealed condition because it has an austenitic structure. Some magnetism may develop after significant cold working.
9. Can 310S stainless steel be welded?
Yes. 310S has good weldability and can be welded using commonly used stainless steel welding processes. Appropriate filler metals and welding procedures should be selected according to the application.
10. What surface finish is available for hot rolled 310S sheet?
The most common industrial surface is No.1 / HRAP (Hot Rolled, Annealed and Pickled). Other surface treatments may be available depending on the required application.
