ASTM A501 Grade B is a specification for hot-formed welded carbon steel structural tubing. This standard covers various grades of carbon steel tubing used for structural applications. In this article, we will explore the material, specification, key features, chemical composition, mechanical properties, steel grade, application, and possible alternative grades of ASTM A501 Grade B.
ASTM A501 Grade B specifies the requirements for hot-formed welded carbon steel structural tubing. The tubing is produced in round, square, and rectangular shapes, with a minimum wall thickness of 0.180 inches (4.57 mm). The maximum wall thickness should not exceed 0.375 inches (9.53 mm). The tubing is available in various sizes and lengths, meeting the dimensional requirements outlined in the specification.
The key features of ASTM A501 Grade B hot-formed welded carbon steel structural tubing include:
| Element | Composition (%) |
|---|---|
| Carbon (C) | 0.30 max |
| Manganese (Mn) | 1.40 max |
| Phosphorus (P) | 0.040 max |
| Sulfur (S) | 0.050 max |
| Property | Value |
|---|---|
| Tensile Strength | 58,000 psi (400 MPa) min |
| Yield Strength | 36,000 psi (250 MPa) min |
| Elongation in 2 inches | 23% min |
ASTM A501 Grade B is a specific grade of carbon steel used for hot-formed welded structural tubing. It offers a balance of strength and weldability, making it suitable for a wide range of structural applications.
ASTM A501 Grade B hot-formed welded carbon steel structural tubing finds its application in various industries, including construction, infrastructure, and manufacturing. It is commonly used in the fabrication of buildings, bridges, towers, and other structures where high strength and durability are required.
While ASTM A501 Grade B is a widely used specification, there are alternative grades available that may suit specific application requirements. Some possible alternative grades include ASTM A500, ASTM A513, and ASTM A847. These grades offer similar properties and can be considered as alternatives based on specific project needs.
