| Element | Minimum % |
|---|---|
| Carbon | 0.06 |
| Manganese | 0.27-0.63 |
| Phosphorus | 0.035 |
| Sulfur | 0.035 |
The mechanical properties of the ASTM A179 ERW welded steel tube are as follows:
| Property | Value |
|---|---|
| Tensile Strength | 325 MPa (min) |
| Yield Strength | 180 MPa (min) |
| Elongation | 35% (min) |
| Hardness | 72 HRB (max) |
The ASTM A179 ERW welded steel tube belongs to the low-carbon steel grade family, which includes a range of materials suitable for welding, forming, and machining.
This galvanized square tube finds its application in various construction projects. It provides exceptional structural support and contributes to the durability of buildings and structures. Some common applications include:
Though the ASTM A179 ERW welded steel tube is widely used in construction, there are alternative grades available that can be considered depending on specific requirements. Some possible alternative grades include ASTM A500, ASTM A513, and ASTM A53.
