    • Corrosion Resistance: Painting, galvanizing, and pickling techniques can protect mechanical tubes from corrosion.
    What is ASTM A513? 

    ASTM A513 is a standard electric-resistance-welded (ERW) carbon and alloy steel mechanical tubing specification. This specification covers round, square, rectangular, and special-shaped tubing suitable for various mechanical applications, such as machinery, automotive parts, construction equipment, and other structural applications.

    ASTM A513 mechanical steel tubing must adhere to specific requirements to ensure its quality and suitability for mechanical use. Some of the essential requirements outlined in the specification include:

    • Chemical Composition: The steel grade substrate used in the tubing will meet specific chemical composition limits, ensuring the appropriate balance of elements to impart the desired mechanical properties.
    • Tensile Strength and Yield Strength: The tubing should have specified minimum tensile and yield strengths, indicating its ability to withstand applied forces without failure.
    • Wall Thickness and Outside Diameter Tolerances: The tubing's dimensions, particularly its wall thickness and outside diameter, must meet specific tolerances to ensure uniformity and proper fit in applications.
    • Surface Finish: The tubing should have a smooth, clean surface finish, free from defects that could compromise its end use.

    It's worth noting that ASTM A513 tubing is available in various grades, such as 1008, 1010, 1015, 1020, 1025, 1030, 4130, and 4140. Each grade has its specific chemical composition and mechanical properties. Manufacturers and engineers may select the appropriate grade based on the intended application and the required mechanical characteristics.
