Whether you're an engineer designing structural components or a procurement specialist sourcing for general-purpose applications, this article will clarify why 304N stainless steel (UNS S30451) 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 s30452, sa 240/a 240 uns s30453, 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 S30451, commonly known as 304N stainless steel, is an austenitic 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 higher strength than standard 304 stainless steel, good corrosion resistance, and excellent formability, making it ideal for industries such as structural engineering, food processing, and general manufacturing. The nitrogen addition enhances strength and pitting resistance compared to sa 240/a 240 uns s30400, while maintaining good weldability for various applications.
The ASME SA240/ASTM A240 UNS S30451 stainless steel sheet offers improved strength over sa 240/a 240 uns s30453 due to its higher nitrogen content, and better corrosion resistance than sa 240/a 240 uns s30500 due to its balanced alloy composition. While it is less corrosion-resistant than molybdenum-containing grades like sa 240/a 240 uns s31651, its enhanced strength makes it a preferred choice for applications requiring durability and formability.
Key benefits of ASME SA240/ASTM A240 UNS S30451 stainless steel sheet include:
Case Study: A structural engineering firm in India used sa 240/a 240 uns s30451 sheets for building frameworks, achieving a 15% increase in strength compared to sa 240/a 240 uns s30400 while maintaining corrosion resistance in mild environments.

ASME SA240/ASTM A240 UNS S30451offers 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 protective oxide layer and improved pitting resistance, with a pitting resistance equivalent number (PREN) of ~19-21. This makes it suitable for applications like structural components and food processing equipment, 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 controlled carbon content (≤ 0.08%) of ASME SA240/ASTM A240 UNS S30451 ensures good weldability by reducing the risk of carbide precipitation and intergranular corrosion during welding, making it suitable 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 S30451 offers comparable weldability but is less optimized for high-temperature applications. For applications requiring superior weldability, sa 240/a 240 uns s30453 with its lower carbon content is a better choice.
