ASME SA240/ASTM A240 UNS S42900, a ferritic stainless steel, contains 14.0-16.0% chromium, offering good corrosion resistance, moderate strength, and good weldability. It is designed for applications requiring durability in mild to moderately corrosive environments, such as industrial equipment, appliances, and automotive trim. The low carbon content (≤ 0.12%) ensures good weldability compared to martensitic grades like sa240/a240 uns s41000, while its ferritic structure provides excellent resistance to scaling at temperatures up to 675°C (1247°F).
The ASME SA240/ASTM A240 UNS S42900 stainless steel sheet offers improved corrosion resistance compared to sa240/a240 uns s41003 due to higher chromium content and is more cost-effective than high-alloy grades like sa240/a240 uns s44400 for industrial and automotive applications. While it is less corrosion-resistant in chloride-rich environments than grades like sa240/a240 uns s42035, its affordability and weldability make it a preferred choice for industrial components and decorative applications.
Key benefits of ASME SA240/ASTM A240 UNS S42900 stainless steel sheet include:
Case Study: An appliance manufacturer in India used sa240/a240 uns s42900 sheets for decorative panels, achieving a 25% cost reduction compared to sa240/a240 uns s43000 while maintaining excellent corrosion resistance and aesthetic appeal.

The density of ASME SA240/ASTM A240 UNS S42900 stainless steel sheet is approximately 7.70 g/cm³ (0.278 lb/in³). This density is typical for ferritic stainless steels, reflecting its composition with low nickel and high chromium content. The consistent density ensures predictable performance in applications requiring precise weight calculations, such as industrial equipment and automotive trim. Compared to grades like sa240/a240 uns s41003 (7.70 g/cm³) and sa240/a240 uns s42035 (7.75 g/cm³), the density is similar, making UNS S42900 a lightweight, cost-effective option for industrial and decorative applications.
Keywords: ASME SA240/ASTM A240 UNS S42900 density, UNS S42900 density
ASME SA240/ASTM A240 UNS S42900offers good corrosion resistance in mild to moderately corrosive environments due to its 14.0-16.0% chromium content, which forms a protective oxide layer. With a pitting resistance equivalent number (PREN) of ~14.0-16.0, it is suitable for industrial equipment, appliances, and automotive trim exposed to non-aggressive environments. It outperforms lower-chromium grades like sa240/a240 uns s41003 but is less resistant to chloride-rich environments compared to molybdenum-containing grades like sa240/a240 uns s42035 or sa240/a240 uns s44400. For high-temperature oxidation resistance, it performs similarly to sa240/a240 uns s43000.

The low carbon content (≤ 0.12%) in ASME SA240/ASTM A240 UNS S42900 ensures good weldability by minimizing carbide precipitation, making it more weldable than martensitic grades like sa240/a240 uns s41000 but less weldable than stabilized grades like sa240/a240 uns s41045 due to the absence of niobium or titanium. It can be welded using common techniques such as TIG, MIG, and shielded metal arc welding, with low-carbon ferritic or austenitic filler materials to maintain corrosion resistance and strength. Compared to sa240/a240 uns s41003, UNS S42900 offers similar weldability but better corrosion resistance due to higher chromium content. For applications requiring superior weldability, sa240/a240 uns s41045 or sa240/a240 uns s42035 are viable alternatives.
