Whether you're an engineer designing furnace components or a procurement specialist sourcing for petrochemical applications, this article will clarify why 310HCb stainless steel (UNS S31041) is a trusted option. Explore our sa 240/a 240 uns stainless grades portfolio for related grades like sa 240/a 240 uns s30615, sa 240/a 240 uns s30815, sa 240/a 240 uns s30909, sa 240/a 240 uns s30940, sa 240/a 240 uns s31040, sa 240/a 240 uns s31050, and sa 240/a 240 uns s31060.
ASME SA240/ASTM A240 UNS S31041, known as 310HCb, is an austenitic stainless steel with 24.0-26.0% chromium, 19.0-22.0% nickel, 0.04-0.10% carbon, and niobium stabilization for enhanced high-temperature strength and creep resistance. It is designed for high-temperature applications requiring robust strength, excellent corrosion resistance, and moderate weldability, making it ideal for industries such as power generation, petrochemical, and furnace manufacturing. The elevated carbon content enhances high-temperature strength compared to sa 240/a 240 uns s31040, while niobium stabilization improves weldability compared to sa 240/a 240 uns s31060.
The ASME SA240/ASTM A240 UNS S31041 stainless steel sheet offers superior high-temperature strength compared to sa 240/a 240 uns s30909 and better corrosion resistance than sa 240/a 240 uns s30815 due to its higher chromium and nickel content. While it is less corrosion-resistant in highly aggressive environments than grades like sa 240/a 240 uns s31050, its high-temperature strength and creep resistance make it a preferred choice for furnace and heat exchanger applications.
Key benefits of ASME SA240/ASTM A240 UNS S31041 stainless steel sheet include:
Case Study: A power generation plant in India used sa 240/a 240 uns s31041 sheets for furnace components, achieving a 30% longer service life compared to sa 240/a 240 uns s30909 due to its superior high-temperature strength and creep resistance.

The density of ASME SA240/ASTM A240 UNS S31041 stainless steel sheet is approximately 7.89 g/cm³ (0.285 lb/in³). This density is typical for high-chromium and high-nickel austenitic stainless steels, reflecting the material's composition, which includes niobium stabilization and elevated carbon content. The consistent density ensures predictable performance in applications requiring precise weight calculations, such as furnace components and heat exchangers. Compared to grades like sa 240/a 240 uns s30815 (7.80 g/cm³) and sa 240/a 240 uns s31050 (7.89 g/cm³), the density is similar, making UNS S31041 a reliable choice for weight-sensitive high-temperature applications.

ASME SA240/ASTM A240 UNS S31041offers excellent corrosion resistance in high-temperature environments, such as petrochemical and power generation settings. Its 24.0-26.0% chromium and 19.0-22.0% nickel content provide a robust protective oxide layer, with a pitting resistance equivalent number (PREN) of ~24-26, suitable for applications like furnace linings and heat exchanger tubes. It outperforms sa 240/a 240 uns s30615 and sa 240/a 240 uns s30940 in high-temperature corrosion resistance due to its higher chromium and nickel content. For highly corrosive environments, such as chloride-rich conditions, grades like sa 240/a 240 uns s31050 or sa 240/a 240 uns s31254 are recommended.

The elevated carbon content (0.04-0.10%) of ASME SA240/ASTM A240 UNS S31041 provides moderate weldability, with niobium stabilization reducing the risk of carbide precipitation and intergranular corrosion compared to sa 240/a 240 uns s31060. It can be welded using techniques such as TIG, MIG, and shielded metal arc welding, with niobium-containing filler materials and low heat input to minimize sensitization. Compared to sa 240/a 240 uns s31040, UNS S31041 is less weldable due to its higher carbon content but offers superior high-temperature strength. For applications requiring enhanced weldability, sa 240/a 240 uns s31050 is a better choice.
