Neil Metals stands out as a top manufacturer and supplier of Stainless Steel 304L Flat Bars, proudly based in Kolkata, India. We’re recognized for our precision-engineered stainless steel products, and our 304L flat bars are perfect for applications that demand outstanding corrosion resistance, solid weldability, and dependable strength. Crafted in line with ASTM A276 and other international standards, our flat bars come in a variety of thicknesses and widths to meet the diverse needs of various industries. We cater to sectors like construction, chemical processing, food & beverage, and pharmaceuticals, providing products that excel in performance, durability, and cost-effectiveness for both structural and fabrication purposes.
Stainless Steel 304L is a low-carbon version of 304, containing about 18–20% chromium, 8–12% nickel, and a maximum of 0.03% carbon. This composition enhances its weldability and minimizes the risk of carbide precipitation during welding. With mechanical properties that include a tensile strength of around 485 MPa, yield strength of 170 MPa, and an elongation of about 40%, SS 304L flat bars are well-suited for both structural and pressure applications, thanks to their excellent corrosion resistance across a wide range of environments.
