What Are ASTM A500 Tubes & Pipes?
ASTM A500 Tubes & Pipes refer to carbon steel tubing manufactured in accordance with the ASTM A500 / A500M standard specification. This standard covers cold-formed welded and seamless carbon steel structural tubing produced in round, square, and rectangular shapes. It is one of the most common specifications for hollow structural sections (HSS) used in North America.
The A500 Steel covered by this specification is typically a low-carbon steel, offering a good combination of strength, weldability, and ductility, making it suitable for applications where load-bearing capability and structural integrity are paramount. While commonly produced as welded (Electric Resistance Welded - ERW), the ASTM A500 specification also allows for seamless tubing, though ERW is more prevalent for this standard. Key grades within ASTM A500 include Grade B and Grade C (with Grade C having higher strength), and more recently Grade D. ASTM A500 Gr B Pipe (or tube) is a very common and versatile choice.

Dimensional Tolerances for ASTM A500 Tubing
ASTM A500 Steel Structural Tubing is manufactured to specific dimensional tolerances to ensure consistency and proper fit-up in structural assemblies. The standard provides detailed tables for various tolerances including outside dimensions, wall thickness, straightness, and twist.
| Outside Large Flat Dimension, inches [mm] | Large Flat Dimension Tolerance A, plus and minus, inches [mm] |
|---|---|
| 2½ [63.5] or under | 0.020 [0.51] |
| Over 2½ [63.5] to 3½ [88.9], inclusive | 0.025 [0.64] |
| Over 3½ [88.9] to 5½ [139.7], inclusive | 0.030 [0.76] |
| Over 5½ [139.7] | 0.01 times the specified large flat dimension |
Heat Treatment for ASTM A500 Tubes & Pipes:
ASTM A500 Tubes & Pipes are typically supplied in conditions suitable for their intended structural and mechanical applications. The following table outlines common heat treatment considerations and conditions:
| Heat Treatment / Condition | Typical Temperature Range °F [°C] (for Carbon Steels like A500) | Purpose & Key Characteristics | Applicability to ASTM A500 |
|---|---|---|---|
| As-Welded (ERW) | N/A (Localized heating during welding) | Properties are primarily from the steel chemistry and cold-forming prior to welding. Most common supply condition. | Standard condition for many ASTM A500 Grade A, B, & C tubes. Weld seam may be processed to be metallurgically similar to the base metal as per A500. |
| Stress Relieving | 1000 - 1200 [540 - 650] | Reduces internal stresses from cold-forming & welding, improves dimensional stability, can slightly improve toughness and reduce risk of distortion/cracking. | Can be applied to A500 tubing after forming or fabrication if required by the application or to improve formability for subsequent severe operations. |
| Normalizing | 1600 - 1750 [870 - 955] | Refines grain structure, improves uniformity of mechanical properties (including weld/HAZ), enhances toughness. | Less common as a final supply condition for general A500 structural use but is a permissible treatment. May be used if specific toughness or forming properties are needed. |
| Annealing (Full or Process) | Full: 1550 - 1650 [845 - 900] Process: 1000 - 1300 [540 - 705] |
Full Anneal: Produces maximum softness and ductility. Process Anneal: Softens for further cold work, relieves stress. |
Full annealing is less common for A500 structural tubes. Process annealing might be used for tubes intended for severe cold forming. |
| Quenching & Tempering (Q&T) | N/A | Achieves high hardness and strength (typical for medium/high carbon or alloy steels). | Generally NOT applicable to standard ASTM A500 carbon steel grades (A, B, C, D). Their low carbon content does not allow for significant hardening via Q&T. |
