Starc Metals, based in Canberra, Australia, has earned a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel products, particularly 310S flat bars. Known for their precision engineering and outstanding quality, Starc Metals crafts flat bars that are built to withstand the tough demands of the industrial, construction, and manufacturing sectors. By blending cutting-edge production methods with rigorous quality control, the company guarantees consistent performance, durability, and resistance to corrosion. With a strong commitment to reliability and excellence, Starc Metals supplies Australian businesses with high-grade stainless steel 310S flat bars, which offer remarkable strength, thermal stability, and long-lasting performance even in challenging environments.
Stainless steel 310S flat bars are made from an austenitic alloy that contains 24–26% chromium and 19–22% nickel, along with a low carbon content of ≤0.08% to enhance weldability. They boast a tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of 40%, which translates to excellent ductility and resilience at high temperatures. This alloy is known for its exceptional resistance to oxidation and creep, maintaining its mechanical integrity in environments reaching up to 1100°C. These characteristics make 310S flat bars perfect for applications that require durability, heat resistance, and corrosion protection in industrial and high-temperature settings.

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.
You’ll find stainless steel 310S flat bars widely used in situations that demand heat and corrosion resistance. They are particularly suited for furnace components, kiln parts, heat exchangers, and gas-turbine components. In the chemical and petrochemical industries, 310S flat bars stand up to oxidation and attacks from acidic or alkaline environments. Their thermal stability and mechanical strength make them ideal for boiler parts, power plant equipment, and structural components that face extreme heat. Additionally, they are utilized in aerospace, food processing, and marine equipment, providing dependable, long-lasting performance in environments that require durability and corrosion resistance.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
