Gangsteel showcases sa240/a240 uns s44627, a high-performance super-ferritic stainless steel sheet engineered for exceptional corrosion resistance and high-temperature durability. Compliant with sa240/a240 uns stainless grades standards, including ASTM A240 and ASME SA240, UNS S44627 is ideal for demanding applications such as chemical processing, power generation, and high-temperature industrial systems. As a trusted uns stainless supplier, Gangsteel maintains an inventory exceeding 600 tons and employs advanced manufacturing to deliver precise, tailored solutions globally with rapid delivery.
Gangsteel provides a detailed analysis of ASME SA240/ASTM A240 UNS S44627, covering its chemical composition, density, mechanical properties, corrosion resistance, weldability, surface finishes, equivalent materials, specifications, applications, and pricing per kg. Perfect for engineers and procurement specialists, UNS S44627 offers a robust solution for harsh environments. Explore related grades like sa240/a240 uns s41003 to meet diverse project requirements.
ASME SA240/ASTM A240 UNS S44627, a super-ferritic stainless steel, features 25.0-27.5% chromium, 0.75-1.50% molybdenum, and niobium stabilization (0.05-0.20%), delivering outstanding corrosion resistance, good weldability, and moderate strength. Designed for applications requiring durability in highly corrosive and high-temperature environments, such as chemical reactors and heat exchangers, it benefits from niobium stabilization and low carbon content (≤ 0.015%) to prevent carbide precipitation during welding, outperforming non-stabilized grades like sa240/a240 uns s43000. Its ferritic structure ensures excellent scaling resistance up to 1050°C (1922°F).
Gangsteel notes that UNS S44627 offers superior corrosion resistance compared to sa240/a240 uns s41008 due to higher chromium and molybdenum content, and it is more cost-effective than super-ferritic grades like sa240/a240 uns s44700. Its high corrosion resistance makes it ideal for severe environments.
Key benefits include:
Case Study: A Chinese power plant used UNS S44627 sheets for boiler components, achieving a 20% cost reduction compared to sa240/a240 uns s44700 while maintaining superior corrosion resistance.

Gangsteel emphasizes that ASME SA240/ASTM A240 UNS S44627 offers outstanding corrosion resistance in highly corrosive environments due to its 25.0-27.5% chromium and 0.75-1.50% molybdenum content, with a pitting resistance equivalent number (PREN) of ~26.5-30.5. Ideal for chemical processing and power generation, it outperforms sa240/a240 uns s41008 and sa240/a240 uns s44400 in chloride-rich environments. Its high-temperature oxidation resistance is superior to sa240/a240 uns s43000.

Gangsteel notes that the low carbon content (≤ 0.015%) and niobium stabilization (0.05-0.20%) in ASME SA240/ASTM A240 UNS S44627 ensure good weldability, minimizing carbide precipitation. It outperforms martensitic grades like sa240/a240 uns s41500 and is comparable to sa240/a240 uns s43035. Suitable for TIG, MIG, and shielded metal arc welding, it uses niobium-stabilized or low-carbon ferritic fillers.
