Gangsteel examines the exceptional qualities of sa240/a240 uns s44500, a high-performance ferritic stainless steel sheet from a trusted uns stainless supplier. Compliant with sa240/a240 uns stainless grades standards, including ASTM A240 and ASME SA240, UNS S44500 offers superior corrosion resistance, good weldability, and moderate strength for industrial, architectural, and automotive applications. With over 600 tons in stock and advanced manufacturing, Gangsteel delivers tailored solutions globally with speed and precision.
Gangsteel provides a detailed overview of ASME SA240/ASTM A240 UNS S44500, covering its chemical composition, density, mechanical properties, corrosion resistance, weldability, surface finishes, equivalent materials, specifications, applications, and pricing per kg. Ideal for engineers and procurement specialists, UNS S44500 is a cost-effective choice for demanding environments. Explore related grades like sa240/a240 uns s41003 to meet your project needs.
ASME SA240/ASTM A240 UNS S44500, a ferritic stainless steel, features 20.0-22.0% chromium, offering superior corrosion resistance, good weldability, and moderate strength. It is designed for applications requiring durability in moderately corrosive environments, such as industrial equipment, architectural panels, and automotive components. The low carbon content (≤ 0.02%) and nitrogen control (≤ 0.03%) enhance weldability compared to martensitic grades like sa240/a240 uns s41000, while its ferritic structure ensures excellent scaling resistance up to 850°C (1562°F).
Gangsteel highlights that UNS S44500 provides better corrosion resistance than sa240/a240 uns s43000 due to higher chromium content and is more cost-effective than super-ferritic grades like sa240/a240 uns s44700. While less resistant to severe chloride environments than sa240/a240 uns s44400, its affordability and performance make it ideal for industrial and architectural uses.
Key benefits include:
Case Study: An Indian industrial manufacturer used UNS S44500 sheets for chemical processing equipment, achieving a 20% cost reduction compared to sa240/a240 uns s44400 while maintaining robust corrosion resistance.

Gangsteel notes that the density of ASME SA240/ASTM A240 UNS S44500 is approximately 7.70 g/cm³ (0.278 lb/in³), typical for ferritic stainless steels with high chromium content. This density supports precise weight calculations for applications like industrial panels, aligning with sa240/a240 uns s41003 (7.70 g/cm³) and slightly less than sa240/a240 uns s42035 (7.75 g/cm³).

Gangsteel emphasizes that ASME SA240/ASTM A240 UNS S44500 offers superior corrosion resistance in mild to moderately corrosive environments due to its 20.0-22.0% chromium content, with a pitting resistance equivalent number (PREN) of ~20.0-22.0. Ideal for industrial equipment and architectural applications, it outperforms sa240/a240 uns s41008 but is less resistant to severe chloride environments than sa240/a240 uns s44700. Its high-temperature oxidation resistance is superior to sa240/a240 uns s43932.

Gangsteel highlights that the low carbon content (≤ 0.02%) and nitrogen control (≤ 0.03%) in ASME SA240/ASTM A240 UNS S44500 ensure good weldability, minimizing carbide precipitation. It outperforms martensitic grades like sa240/a240 uns s41500 but is less weldable than stabilized grades like sa240/a240 uns s43035. Suitable for TIG, MIG, and shielded metal arc welding, it uses low-carbon ferritic or austenitic fillers.
