ASTM A105 – Carbon Steel Forgings for Piping Applications
Chemical Compositions (max, %)
| C | Mn | P | S | Si | Cr | Cu | Mo | Ni | V |
| 0.35 | 0.60- 1.05 | 0.035 | 0.040 | 0.1- 0.35 | 0.30 | 0.40 | 0.12 | 0.40 | 0.08 |
Notes:
1) For each reduction of 0.01% below the specified C maximum(0.35%), an increase of 0.06% Mn above the specified maximum (1.05%) will be permitted up to a maximum of 1.35%.
2) The sum of Cu, Ni, Cr, Mo and V shall not exceed 1.00%.
3) The sum of Cr and Mo shall not exceed 0.32%.
