| Phosphorus (max) | 0.035 | A, B | |
| Sulphur (max) | 0.035 | A, B | |
| Silicon | 0.15 - 0.50 | A | |
| 0.13 - 0.55 | B | ||
| Copper (max) | 0.35 | A | |
| 0.38 | B | ||
| Nickel (max) | 0.25 | A, C | |
| 0.28 | B, C | ||
| Chromium (max) | 0.25 | A | |

Notes: A - heat analysis, B - product analysis, C - Manganese may exceed 1.35% on heat analysis, up to a maximum of 1.60%, and Nickel may exceed 0.25% on heat analysis, up to a maximum of 0.50%, provided the heat analysis carbon equivalent (long formula) does not exceed 0.57%. When this option is exercised, the Manganese and Nickel contents on product analysis shall not exceed the heat analysis content by more than 0.12% and 0.03% respectively.
