Whether you're an engineer designing welded structures or a procurement specialist sourcing for food processing applications, this article will clarify why 304LN stainless steel (UNS S30453) is a trusted option. Explore our sa 240/a 240 uns stainless grades portfolio for related grades like sa 240/a 240 uns s30415, sa 240/a 240 uns s30451, sa 240/a 240 uns s30452, sa 240/a 240 uns s30500, sa 240/a 240 uns s30600, sa 240/a 240 uns s30601, and others.
ASME SA240/ASTM A240 UNS S30453, commonly known as 304LN stainless steel, is a low-carbon, nitrogen-enhanced variant of 304 stainless steel with 18.0-20.0% chromium, 8.0-10.5% nickel, and 0.10-0.16% nitrogen. It is designed for applications requiring excellent weldability, enhanced strength, and good corrosion resistance, making it ideal for industries such as food processing, chemical processing, and welded structural applications. The low carbon content (≤ 0.03%) minimizes carbide precipitation, improving weldability compared to sa 240/a 240 uns s30451, while the nitrogen addition enhances strength compared to sa 240/a 240 uns s30400.
The ASME SA240/ASTM A240 UNS S30453 stainless steel sheet offers superior weldability compared to sa 240/a 240 uns s30452 and comparable corrosion resistance to sa 240/a 240 uns s30451, though it is less corrosion-resistant than molybdenum-containing grades like sa 240/a 240 uns s31653. Its combination of weldability and strength makes it a preferred choice for applications requiring robust welded joints.
Key benefits of ASME SA240/ASTM A240 UNS S30453 stainless steel sheet include:
Case Study: A chemical processing plant in India used sa 240/a 240 uns s30453 sheets for welded reactor vessels, achieving a 20% reduction in welding defects compared to sa 240/a 240 uns s30451 due to its superior weldability.

The density of ASME SA240/ASTM A240 UNS S30453 stainless steel sheet is approximately 7.93 g/cm³ (0.286 lb/in³). This density is typical for austenitic stainless steels and reflects the material's composition, which includes high chromium, nickel, and nitrogen content. The consistent density ensures predictable performance in applications requiring precise weight calculations, such as structural engineering and chemical processing equipment. Compared to other grades like sa 240/a 240 uns s30451 and sa 240/a 240 uns s30452, the density remains similar due to their comparable alloy compositions, making UNS S30453 a reliable choice for weight-sensitive applications.

ASME SA240/ASTM A240 UNS S30453offers good corrosion resistance in mild to moderately corrosive environments, such as indoor settings, food processing environments, or areas with low chloride exposure. Its 18.0-20.0% chromium and 8.0-10.5% nickel content, combined with 0.10-0.16% nitrogen, provide a robust protective oxide layer and improved pitting resistance, with a pitting resistance equivalent number (PREN) of ~19-21. This makes it suitable for applications like chemical processing equipment and welded structures, outperforming sa 240/a 240 uns s30500 and sa 240/a 240 uns s30600. For highly corrosive environments, such as chloride-rich conditions, grades like sa 240/a 240 uns s31254 or sa 240/a 240 uns s31653 are recommended.

The low carbon content (≤ 0.03%) of ASME SA240/ASTM A240 UNS S30453 significantly enhances its weldability by minimizing the risk of carbide precipitation and intergranular corrosion during welding, making it superior to sa 240/a 240 uns s30451 and sa 240/a 240 uns s30452 for welded structures. It can be welded using common techniques such as TIG, MIG, and resistance welding, with appropriate filler materials to maintain corrosion resistance and strength. Compared to sa 240/a 240 uns s30415, UNS S30453 offers better weldability due to its lower carbon content, making it ideal for applications requiring robust welded joints, such as chemical reactors.
