What is ASTM A513 Mechanical Tubing？

ASTM A513 Mechanical Tubing is a set of standards established by the American Society for Testing and Materials (ASTM) that govern the manufacturing and quality requirements for electric-resistance-welded (ERW) carbon and alloy steel tubing. It encompasses a range of shapes including round, square, rectangular, and special shapes. This specification outlines the chemical composition, mechanical properties, manufacturing process, dimensional tolerances, and surface finish requirements for the tubing. Typically used in mechanical and structural applications, ASTM A513 tubing finds wide application in industries such as automotive, construction, machinery, furniture, and more, where precision dimensions, consistent quality, and high strength-to-weight ratios are essential.

1. ASTM A513 Mechanical Tubing Material Grade:

ASTM A513 covers several grades of carbon and alloy steel tubing, including but not limited to:

Grade 1008/ Grade 1010/ Grade 1020/ Grade 1026/ Grade 4130/ Grade 4140

2. ASTM A513 Mechanical Tubing Chemical Composition (typical values in percentage):

3. ASTM A513 Mechanical Tubing Mechanical Properties (minimum values):

4. ASTM A513 Mechanical Tubing Delivery Condition:

ASTM A513 tubing is delivered in a hot-finished or cold-finished condition, depending on the manufacturing process.

5. ASTM A513 Mechanical Tubing Permissible Variations in Dimensions:

ASTM A513 specifies the permissible variations in outside diameter, wall thickness, and length for mechanical tubing. These variations depend on the size and shape of the tubing and are outlined in the ASTM A513 standard.
