Electric Resistance Cold Drawn Welded Steel Tubes, also known as ERW tubes, are widely used in the mechanical industry due to their excellent strength, durability, and versatility. One of the most popular standards for ERW steel tubes is ASTM A513, which specifies the material, chemical composition, mechanical properties, and tolerances for this type of tubing. In this article, we will explore the key features of ASTM A513 ERW steel tubes and their applications in various industries.
ASTM A513 ERW steel tubes are made from carbon steel that is hot-rolled and pickled before being cold-drawn through a series of dies. The resulting tubes have a smooth surface finish, high dimensional accuracy, and excellent mechanical properties. The steel used for these tubes is classified into two grades:
ASTM A513 ERW steel tubes are available in a range of sizes, shapes, and wall thicknesses to suit various applications. The standard sizes range from 0.5 inches to 2.5 inches in diameter and from 0.035 inches to 0.120 inches in wall thickness. The tubes can be round, square, or rectangular in shape, depending on the specific requirements of the application.
The chemical composition of ASTM A513 ERW steel tubes is specified in the standard, and the following table shows the typical composition for Grade 1008 and Grade 1010 steel:
| Element | Grade 1008 | Grade 1010 |
|---|---|---|
| Carbon | 0.10% max | 0.08-0.13% |
| Manganese | 0.30-0.50% | 0.30-0.60% |
| Phosphorus | 0.040% max | 0.040% max |
| Sulfur | 0.050% max | 0.050% max |
ASTM A513 ERW steel tubes have excellent mechanical properties that make them ideal for use in the mechanical industry. The following table shows the typical mechanical properties for Grade 1008 and Grade 1010 steel:
| Property | Grade 1008 | Grade 1010 |
|---|---|---|
| Tensile Strength | 45,000 psi | 55,000 psi |
| Yield Strength | 40,000 psi | 50,000 psi |
| Elongation | 20% min | 15% min |
| Hardness (Rockwell B) | 65 max | 75 max |
ASTM A513 ERW steel tubes are available in two grades: Grade 1008 and Grade 1010. The choice of steel grade depends on the specific application and the required mechanical properties.
ASTM A513 ERW steel tubes are widely used in the mechanical industry for a range of applications, including:
