ASTM A500 Grade B is a specification for hot-formed, welded, and seamless carbon steel structural tubing. This grade is primarily used for machine-made applications where precision and strength are required. The rectangular tube produced under this standard exhibits excellent mechanical properties and dimensional accuracy, making it ideal for a variety of structural applications.
The ASTM A500 Grade B rectangular tube is manufactured using carbon steel, ensuring high strength and durability. The tube is produced by either seamless or welded methods, with seamless tubes being commonly preferred for their enhanced mechanical properties. This specification covers both cold-formed welded and seamless carbon steel structures.
The dimensions of the rectangular tube, including wall thickness, outside diameter, and length, vary depending on the specific requirements of the application. The standard size range typically falls within 2" to 12" in rectangular shape.
The ASTM A500 Grade B rectangular tube offers several key features, which contribute to its wide range of applications:
| Chemical Element | Weight (%) |
|---|---|
| Carbon (C) | 0.30 max |
| Manganese (Mn) | 1.35 max |
| Phosphorus (P) | 0.04 max |
| Sulfur (S) | 0.05 max |
| Copper (Cu) | 0.20 min |
| Property | Value |
|---|---|
| Tensile Strength | 58,000 psi (400 MPa) |
| Yield Strength | 46,000 psi (315 MPa) |
| Elongation in 2" (50mm) | 23% |
| Hardness, Brinell (HB) | 120 |
The ASTM A500 Grade B rectangular tube falls under the carbon steel category, specifically low-carbon steel. This grade offers good weldability, formability, and machinability, making it suitable for a wide range of applications.
The ASTM A500 Grade B rectangular tube is commonly used in various industries, including:
While the ASTM A500 Grade B rectangular tube offers a comprehensive range of properties and dimensions, there may be instances where alternative grades may be considered. Some possible alternative grades include ASTM A500 Grade A, ASTM A513, and ASTM A36. It is important to consult the relevant specifications and requirements to determine the most suitable grade for a particular application.
