Chemical Composition
The chemical composition for ASTM A53 ERW Welded Steel Pipe is standardized to ensure weldability and performance.
The maximum percentages for key elements are as follows :
| Element | Grade A, max (%) | Grade B, max (%) |
|---|---|---|
| Carbon (C) | 0.25 | 0.30 |
| Manganese (Mn) | 0.95 | 1.20 |
| Phosphorus (P) | 0.05 | 0.05 |
| Sulfur (S) | 0.045 | 0.045 |
| Copper (Cu)* | 0.40 | 0.40 |
| Nickel (Ni)* | 0.40 | 0.40 |
| Chromium (Cr)* | 0.40 | 0.40 |
| Molybdenum (Mo)* | 0.15 | 0.15 |
| Vanadium (V)* | 0.08 | 0.08 |
*Note: The total composition for these five alloying elements (Cu, Ni, Cr, Mo, V) shall not exceed 1.00%.
Mechanical Properties
The primary distinction between Grade A and Grade B lies in their mechanical strength, making Grade B the choice for higher-stress applications.
| Property | Grade A, minimum | Grade B, minimum |
|---|---|---|
| Tensile Strength | 48,000 psi (330 MPa) | 60,000 psi (415 MPa) |
| Yield Strength | 30,000 psi (205 MPa) | 69,000 psi (240 MPa) |
Applications
ASTM A53 ERW Welded Steel Pipe is designed for multi-industry use, serving critical functions in:
