| Element | WPB Grade (%) |
|---|---|
| Carbon (C) | ≤0.30 |
| Manganese (Mn) | 0.29-1.60 |
| Phosphorus (P) | ≤0.050 |
| Sulfur (S) | ≤0.058 |
| Silicon (Si) | ≥0.10 |

For ASTM A234 Gr. WPB, the carbon equivalent (C.E.), based on heat analysis and the following formula, shall be no greater than 0.50. C.E. = C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15. The C.E. values shall be reported on the test report.
ASTM A234 WPB fittings made from bar or plate may have 0.35 max carbon and that made from forgings may have 0.35 max carbon and 0.35 max silicon with no minimum.
For each reduction of 0.01% below the specified carbon maximum, an increase of 0.06% manganese above the specified maximum will be permitted, up to a maximum of 1.65%.
The sum of copper, nickel, chromium, and molybdenum shall not exceed 1.00%.
