304 / 304L

Overview and Applications

304 / 304L Stainless Steel Unequal Angle is a corrosion-resistant austenitic structural section designed for load-bearing reinforcement and asymmetric structural applications. Featuring two unequal legs forming a 90-degree angle, this stainless steel unequal angle provides flexible support configurations where varying leg dimensions are required. Manufactured in compliance with ASTM A276 specifications, 304 stainless steel unequal angle delivers dependable tensile strength, dimensional stability, and long-term corrosion resistance. The low-carbon 304L grade improves weldability and reduces carbide precipitation, making it ideal for welded structural assemblies in commercial and industrial environments.

Performance & Material Advantages

304 / 304L stainless steel unequal angle offers an excellent combination of strength, corrosion resistance, and fabrication versatility. With approximately 18–20% chromium and 8–10.5% nickel, this grade provides reliable resistance to oxidation, moisture exposure, and mild chemical environments. The unequal leg configuration enhances reinforcement efficiency in structural framing, brackets, and engineered supports. 304L stainless steel unequal angle is particularly suited for fabrication processes including welding, cutting, drilling, and machining, ensuring structural reliability and long-term durability.

Technical Specifications

304 / 304L stainless steel unequal angle is produced to ASTM A276 standards, ensuring controlled chemical composition and consistent mechanical properties. Supplied in hot-rolled condition, these stainless steel unequal angles are available in multiple unequal leg sizes, thicknesses, and standard lengths to meet structural and fabrication requirements. The 304L variant provides enhanced weld integrity and improved resistance to intergranular corrosion in welded assemblies.
