ASTM A178 is a specification for electric-resistance-welded (ERW) carbon-manganese steel tubes. These tubes are primarily used in the manufacturing of boiler and superheater components. The material is designed to withstand high temperatures and pressures, making it suitable for various industrial applications.
The ASTM A178 specification covers two grades of welded steel tubes: Grade A, Grade C, and Grade D. Each grade has specific requirements regarding mechanical properties and chemical composition.
| Element | Grade A (%) | Grade C (%) | Grade D (%) |
|---|---|---|---|
| Carbon (C) | 0.06 - 0.18 | 0.06 - 0.18 | 0.06 - 0.18 |
| Manganese (Mn) | 0.30 - 0.90 | 0.30 - 0.90 | 0.30 - 0.90 |
| Phosphorus (P) | ≤ 0.035 | ≤ 0.035 | ≤ 0.035 |
| Sulfur (S) | ≤ 0.025 | ≤ 0.025 | ≤ 0.025 |
| Silicon (Si) | ≤ 0.40 | ≤ 0.40 | ≤ 0.40 |
| Property | Grade A | Grade C | Grade D |
|---|---|---|---|
| Yield Strength (ksi) | 30 min | 35 min | 40 min |
| Tensile Strength (ksi) | 48 min | 50 min | 55 min |
| Elongation (%) | 30 min | 25 min | 20 min |
| Hardness (Rockwell B) | 80 max | 80 max | 80 max |
ASTM A178 welded steel tubes are primarily used in:
