What is UNS S30453 Stainless steel sheet Equivalent Material?

When selecting materials for demanding applications, understanding material equivalencies across international standards can streamline your project and ensure compliance.

UNS S30453, commonly known as 304LN stainless steel, is a nitrogen-enhanced, low-carbon austenitic alloy prized for its strength and corrosion resistance. But what are its equivalent materials globally?

As a seasoned supplier, Gangsteel has been helping clients navigate these standards for years, delivering high-quality ASME SA240 Gr 304LN sheets, plates, coils, and custom components compliant with ASME SA240 and ASTM A240 standards.

Gangsteel explores the equivalent materials for UNS S30453, its chemical composition, mechanical properties, applications, and pricing, ensuring you have the insights needed to make informed decisions. Whether you're designing cryogenic storage tanks or structural components, understanding these equivalents can save time and ensure performance. Let’s dive in.

Understanding UNS S30453 and Its Equivalents

UNS S30453, or 304LN, is a nitrogen-alloyed version of 304 stainless steel, offering enhanced strength and toughness, particularly in low-temperature environments. The "LN" stands for low carbon and nitrogen-enhanced, making it ideal for applications requiring high strength and good weldability. At Gangsteel, we’ve seen UNS S30453 used in projects where standard 304 falls short, such as in cryogenic or high-stress structural applications.

Its equivalent materials across global standards include:

These equivalents ensure compatibility with standards like ASTM A240 stainless steel sheet or JIS G4304 stainless steel sheet, allowing you to source materials confidently across regions. For instance, specifying ASME SA240 Gr 304LN ensures you get the same performance as EN 1.4311 or JIS SUS 304LN.

Chemical Composition of UNS S30453

The chemistry of UNS S30453 is designed for strength, corrosion resistance, and weldability. Here’s the typical composition:

The nitrogen addition boosts yield strength by up to 50% compared to ASME SA240 Gr 304, while the low carbon content ensures excellent weldability by minimizing carbide precipitation. This makes UNS S30453 a go-to choice for applications requiring both strength and corrosion resistance in mild to moderate environments.
