| Phosphorus (P) | ≤ 0.04 |
| Sulfur (S) | ≤ 0.05 |
| Silicon (Si) | 0.10 - 0.40 |
| Iron (Fe) | Balance |
| Property | Value |
|---|---|
| Yield Strength (min) | 250 MPa |
| Tensile Strength (min) | 400 MPa |
| Elongation | 20% (min) |
| Hardness | 120 HB (max) |
The steel grade used in ASTM A978 pipes typically falls under the standard structural steel grades, such as ASTM A53 or ASTM A106, depending on the specific application and requirements.
ASTM A978 plastic-coated steel pipes are widely used in:
