ASTM A519 Grade 1008 Carbon Steel Tubes (UNS G10080)
ASTM A519 1008 (UNS G10080) is a low-carbon, mild carbon steel used for seamless mechanical tubing applications requiring outstanding formability, high ductility, and excellent welding properties. These tubes are manufactured by hot finishing or cold finishing processes, ensuring superior dimensional accuracy, smooth surface finish, and consistent mechanical strength.
Due to its very low carbon content, ASTM A519 1008 offers excellent cold-working characteristics, making it ideal for deep drawing, bending, swaging, flaring, expansion, machining, and fabrication. The material provides a perfect balance between strength and flexibility, making it suitable for automotive components, hydraulic cylinders, machinery parts, and structural applications. The inclusion of UNS G10080 ensures global identification and material traceability across industries.
ASTM A519 Grade 1008 seamless tubing is commonly utilized in precision engineering applications where reliable performance, smooth internal surfaces, and uniform wall thickness are essential. Its high weldability allows it to be easily integrated into complex systems without compromising structural integrity. Designed for mechanical, industrial, and engineering applications, TP1008 tubes deliver long-lasting performance with consistent strength and durability.
