What Is A513 Steel Mechanical Tubing?
A513 is an ASTM specification for electric-resistance-welded carbon steel mechanical tubing. It is designed for mechanical and non-pressure-bearing applications rather than piping or pressure service. A513 mechanical tubing is available in both hot-rolled electric-welded and cold-rolled electric-welded forms for a wide range of tolerance and surface finish requirements.A513 Carbon Steel Square Tube Specifications
Totten Tubes stocks A513 carbon steel square tubing in both HREW and CREW forms, including A513-1 HREW, A513-2 CREW, combination HREW/CREW, and A513 Black Kote options. Tubing is available in a wide range of sizes, with standard mill lengths and cut-to-length services available.Square tubing sizes typically range from approximately 3/8" x 3/8" through 20" x 20", depending on wall thickness and specification. Lengths are available in 20-foot and 24-foot sections, with custom cuts available upon request. For more information, view our in-depth A500 Steel and A513 Carbon Steel Tube specifications.
Hot-Rolled Electric-Welded (HREW) Square Tubing
A513-1 HREW square tubing offers solid mechanical strength and uniform wall thickness. It is commonly selected for fabricated components and general mechanical applications where surface finish is not the primary concern.Cold-Rolled Electric-Welded (CREW) Square Tubing
A513-2 CREW square tubing provides tighter dimensional tolerances and a smoother surface finish. This material is often used for applications that require a more precise finish.Advantages of Mechanical A513 ASTM Carbon Steel Square Tube
Compared to other steel tubing types, A513 ASTM steel tubing offers the uniformity and tensile strength needed for a wide variety of non-load-bearing applications. Mechanical A513 carbon steel advantages include:- Meets ASTM industry standards
- Pliable and easy to bend
- Can adhere to tight tolerances versus other alloys
- Does not require stenciling

Mechanical vs. Structural Square Tubing: A513 vs. A500
ASTM A513 square tubing is produced for mechanical, non-load-bearing applications that benefit from tight tolerances and consistent dimensions. ASTM A500 square tubing is classified as structural tubing and is intended for load-bearing structural uses. Projects that require dimensional precision often favor A513, while structural frameworks rely on A500.Learn more in our A513 vs. A500 square tubing comparison resource.
