310S Stainless Steel Bar is a high-alloy austenitic stainless steel known for its outstanding resistance to oxidation, scaling, and corrosion at elevated temperatures. It is designed specifically for applications that require exceptional heat resistance and stability under continuous exposure to high temperatures.
Composition:
The typical chemical composition of 310S Stainless Steel includes:
- Chromium (Cr): Approximately 25% which provides excellent resistance to oxidation and corrosion.
- Nickel (Ni): Around 20%, contributing to the formation of an austenitic structure and enhancing its overall corrosion resistance as well as high-temperature properties.
- Silicon (Si) and Manganese (Mn): Added in small amounts to improve strength and stability at elevated temperatures.
- Carbon (C): Controlled at low levels to minimize carbide precipitation and enhance resistance to intergranular corrosion.
- Other elements like Phosphorus (P), Sulfur (S), and traces of other metals may also be present.
Characteristics:
1. High-Temperature Resistance: Offers superior resistance to high temperatures up to around 1150°C (2102°F) with intermittent service up to 1200°C (2192°F).
2. Oxidation Resistance: Exhibits exceptional resistance to scaling and oxidizing environments due to its high chromium content.
3. Stress-Corrosion Cracking Resistance: Has good resistance to stress-corrosion cracking even in chloride-containing environments at elevated temperatures.
4. Weldability: Can be welded using standard fusion methods, but post-weld heat treatment might be necessary to restore maximum corrosion resistance.
5. Formability: Although less formable than lower alloyed grades like 304, it can still be worked and formed into bars for various applications.
Use:
1. Heat Treatment Furnaces: Components such as furnace parts, radiant tubes, heating elements, and muffles.
2. Petroleum Refining Industry: Equipment subjected to high temperatures and sulfur-bearing gases, including flue gas desulfurization systems.
3. Power Generation: Boiler components, superheater and reheater tubing, combustion chamber liners, and exhaust systems.
4. Metal Processing Industry: In equipment like annealing boxes, kilns, incinerators, and waste heat recovery units.
5. Chemical Processing: High-temperature sections of process equipment where corrosion and thermal cycling are concerns.
In summary, 310S Stainless Steel Bar is a premium material designed for demanding high-temperature applications where its extraordinary resistance to heat, oxidation, and corrosion make it the preferred choice. Its unique combination of high chromium and nickel content ensures long-term integrity and performance in some of the harshest industrial environments.
