Chung Metal Manufacturer & Suppliers in Da Nang, Vietnam, offers high-quality Stainless Steel 304L Flat Bars to be utilized in construction, manufacturing, and food processing sectors. 304L is a low-carbon alloy of the renowned 304 grade that provides better weldability and immunity to intergranular corrosion. We produce these flat bars to ASTM A276/A240 specifications, with customizable dimensions and surface finish. Strong quality control and effective logistics, Chung Metal produces flat bars that are strong, versatile, and corrosion-resistant — perfect for hygienic environments and mild chemical exposure in various industries.
Stainless Steel 310S contains ~24–26% chromium, 19–22% nickel, and ≤0.08% carbon. It provides high-temperature strength and oxidation resistance up to 1100°C. Tensile strength is ~520 MPa, yield strength ~205 MPa, and elongation ~40%. Density is ~7.9 g/cm³. Hardness is approximately 85–95 HB. The alloy retains ductility at high temperatures and is weldable with conventional techniques. The presence of low carbon decreases the chances of sensitization upon welding, enhancing its service life in cyclic heating high-temperature applications.

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 are suited for use in furnace components, heat exchangers, burner nozzles, and other industrial equipment used at high temperatures. They are also applied in petrochemical reactors, kilns, and thermal processing plants. They are applied in boiler tubes, boiler baffles, and radiant tubes in power generation. 310S can be applied in situations where there is frequent temperature change, like incinerators and gas turbines. They have a high resistance to sulfidation and oxidation and thus can be applied in metallurgy and heat treatment operations. Applications that involve building structures are fire-resistant barriers, elevator shafts, and structural supports in high-temperature areas.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
