ASME SA240/ASTM A240 UNS S41003, a ferritic stainless steel, contains 10.5-12.5% chromium and low carbon (≤ 0.03%), offering a balance of corrosion resistance, good weldability, and moderate strength. It is designed for applications requiring durability in mild corrosive environments, such as structural components, industrial equipment, and automotive applications. The low carbon content and nitrogen addition (≤ 0.03%) enhance weldability and toughness compared to martensitic grades like sa240/a240 uns s41000, while its ferritic structure provides good resistance to scaling at temperatures up to 650°C (1202°F).
The ASME SA240/ASTM A240 UNS S41003 stainless steel sheet offers improved weldability compared to sa240/a240 uns s41000 and is more cost-effective than higher-alloy grades like sa240/a240 uns s44400 for structural and industrial applications. While it is less corrosion-resistant in chloride-rich environments than grades like sa240/a240 uns s41500, its combination of affordability, weldability, and moderate strength makes it a preferred choice for structural supports and industrial components.
Key benefits of ASME SA240/ASTM A240 UNS S41003 stainless steel sheet include:
Case Study: An industrial equipment manufacturer in India used sa240/a240 uns s41003 sheets for structural supports in a chemical processing plant, achieving a 30% cost reduction compared to sa240/a240 uns s40900 while maintaining reliable corrosion resistance and weldability.

The density of ASME SA240/ASTM A240 UNS S41003 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 nitrogen addition. The consistent density ensures predictable performance in applications requiring precise weight calculations, such as structural supports and industrial components. Compared to grades like sa240/a240 uns s40500 (7.70 g/cm³) and sa240/a240 uns s41500 (7.80 g/cm³), the density is similar, making UNS S41003 a lightweight, cost-effective option for structural applications.

ASME SA240/ASTM A240 UNS S41003offers good corrosion resistance in mild atmospheres, water, and some chemical environments due to its 10.5-12.5% chromium content, which forms a protective oxide layer. With a pitting resistance equivalent number (PREN) of ~10.5-12.5, it is suitable for structural applications and industrial components exposed to non-aggressive environments. It outperforms carbon steels but is less resistant to chloride-rich environments compared to molybdenum-containing grades like sa240/a240 uns s44400 or sa240/a240 uns s41500. For high-temperature oxidation resistance, grades like sa240/a240 uns s43000 are recommended.

The low carbon content (≤ 0.03%) and nitrogen addition (≤ 0.03%) in ASME SA240/ASTM A240 UNS S41003 ensure good weldability by minimizing carbide precipitation, making it more weldable than martensitic grades like sa240/a240 uns s41000 but slightly less weldable than titanium-stabilized grades like sa240/a240 uns s40910 due to the absence of stabilizing elements. 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 s41008, UNS S41003 offers similar weldability with improved toughness due to nitrogen. For applications requiring superior weldability, sa240/a240 uns s40910 or sa240/a240 uns s44400 are viable alternatives.
