George Metals, a leading manufacturer and supplier located in Houston, USA, specializes in providing top-notch Stainless Steel 304L Square Bars and Rods. These products are crafted with precision, strength, and impressive corrosion resistance in mind. As a low-carbon variant of 304, 304L stands out for its excellent weldability and resistance to intergranular corrosion, making it perfect for critical fabrication tasks. Manufactured according to ASTM A276 and A479 standards, these square bars and rods boast a fantastic surface finish, tight dimensional tolerances, and dependable mechanical properties. George Metals caters to a variety of industries, including construction, food processing, pharmaceuticals, marine, and chemical processing, offering customized 304L products for both structural and precision applications
Stainless Steel 304L Square Bars and Rods are made up of roughly 18–20% Chromium, 8–12% Nickel, and a maximum of 0.03% Carbon. The lower carbon content enhances resistance to intergranular corrosion, particularly after welding. This alloy delivers a tensile strength ranging from 485–620 MPa, along with good elongation, formability, and toughness across a broad temperature spectrum. Its austenitic structure guarantees excellent machinability and cold working capabilities. George Metals ensures that every bar adheres to strict quality standards, providing consistent mechanical performance and dimensional accuracy suitable for both industrial manufacturing and high-specification fabrication.
