Product Description
ASTM A513 is a carbon steel mechanical tubing specification produced with tight dimensional tolerances and consistent mechanical properties. Typically manufactured using Electric Resistance Welding (ERW), it is widely used in applications requiring precision, strength, and uniformity. Available in multiple shapes including round, square, and rectangular, ASTM A513 tubing supports a wide range of industrial and structural uses.
Product Benefits
Excellent dimensional accuracy and repeatability. Smooth surface finish for easy fabrication and coating. Wide availability of shapes and sizes. Cost-effective alternative to seamless tubing. Good strength-to-weight ratio. Compatible with welding, machining, and forming processes.
Product Advantages
Tight tolerance control for precise assemblies. High versatility across automotive, agricultural, construction, and industrial markets. Strong weld seam integrity due to ERW manufacturing. Available in hot-rolled and cold-drawn (DOM) options. Custom lengths, finishes, and secondary processing available.
Specifications & Requirements
Manufactured to ASTM A513 specification standards. Available in Types 1, 2, 5, and 6. Conforms to defined chemical composition limits. Mechanical properties vary by grade and processing method. Meets dimensional tolerance requirements for OD, ID, wall thickness, and straightness.
Product Properties
Good ductility and formability. Moderate to high tensile strength depending on grade. Excellent machinability and weldability. Uniform wall thickness. Clean surface condition, especially for cold-drawn products.
Product Wall Thickness Options
Available in a broad range of wall thicknesses from light-wall to heavy-wall configurations. Custom thicknesses can be produced depending on application needs.
Product Materials & Manufacturing
Manufactured from carbon steel strip or coil. Produced primarily using Electric Resistance Welding (ERW). Optional cold drawing process (DOM) improves dimensional accuracy and surface finish. Additional processes may include cutting, deburring, annealing, or coating.
Product Comparable Options
ASTM A500 structural tubing for structural applications. ASTM A106 seamless pipe for pressure applications. DOM tubing for improved precision and finish. ASTM A179/A192 tubing for heat transfer applications.
Additional Notes
Commonly used in automotive components, machinery parts, furniture, and structural supports. Selection of proper grade depends on strength, finish, and tolerance requirements. Value-added services such as cutting, fabrication, and coating are often available.
