Applications
Grade 304LN stainless steel is widely used in the following applications:
International standards regulate 304LN stainless steel to ensure its quality, safety, and performance in various industries. These standards define the alloy's chemical composition, mechanical properties, and testing requirements, ensuring reliability for critical applications.
ASTM A240/A240M and ASTM A276 define the chemical composition, mechanical properties, and heat treatment conditions for 304LN stainless steel in flat-rolled, plate, and bar forms. ASTM A312 governs seamless and welded stainless steel pipes, making it relevant for applications like pipelines and chemical processing systems, which rely on 304LN for its corrosion resistance and strength.
304LN stainless steel is designated as UNS S30453. This designation standardizes the identification of 304LN across industries, ensuring consistent specifications and performance.
In Europe, 304LN stainless steel is classified as EN 1.4311 under EN 10088-1 for general applications and EN 10216-5 for pressure-purpose tubes. These standards specify the chemical composition and mechanical properties required for structural and engineering applications.
ISO standards, such as ISO 15510, define the chemical composition of 304LN for global compatibility. This ensures that the alloy meets international benchmarks for quality and performance.
