Neil Metals, located in Kolkata, India, has built a solid reputation as a manufacturer and supplier of top-notch Stainless Steel 310S Flat Bars. These bars are designed to provide reliable solutions for industries that face extreme heat and corrosive conditions. With a commitment to precision manufacturing and rigorous quality control, Neil Metals ensures that their flat bars meet global standards, offering durability, high-temperature strength, and impressive oxidation resistance. The company caters to essential sectors like power generation, petrochemicals, furnaces, and thermal processing. By prioritizing timely delivery, customization, and technical know-how, Neil Metals has established itself as a trusted source for Stainless Steel 310S Flat Bars across a wide range of industrial applications.
Stainless Steel 310S Flat Bars are made up of 24–26% chromium, 19–22% nickel, and a maximum of 0.08% carbon, with the remainder being iron along with trace amounts of manganese, silicon, and phosphorus. This unique composition provides them with exceptional resistance to oxidation and sulfidation at high temperatures. The bars boast mechanical properties like a tensile strength ranging from 520 to 750 MPa and a yield strength of about 205 MPa. Even at elevated temperatures, 310S maintains good ductility and toughness, and its lower carbon content enhances weldability while minimizing the risk of intergranular corrosion after exposure to heat.

Stainless Steel 310S Flat Bars are primarily used in high-temperature applications, such as furnace parts, heat exchangers, burner parts, and chemical processing equipment, due to their excellent oxidation and corrosion resistance.
Stainless Steel 310S performs exceptionally well in high-temperature environments, maintaining strength and resistance to oxidation up to 1,100°C (2,012°F). Its low carbon content minimizes carbide precipitation, ensuring better stability and resistance to thermal cycling and oxidation.
Yes, Stainless Steel 310S can be welded and fabricated with relative ease. Its low carbon content reduces the risk of carbide precipitation during welding, ensuring strong welds. However, preheating and post-weld heat treatment may be necessary for optimal results.
Stainless Steel 310S Flat Bars find extensive use in high-temperature and corrosive environments across various industries. In power plants and thermal processing facilities, they are commonly used for boiler components, heat exchanger plates, and structural supports. The petrochemical and refinery industries rely on them for burner assemblies, flue gas lines, and pressure-retaining components. Their resistance to scaling and thermal fatigue makes them perfect for furnace linings, cement kiln parts, and marine exhaust systems. Additionally, 310S flat bars are utilized in food processing and metallurgy, where strength and corrosion resistance under heat are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
