| Cobalt | 0.03 to 0.40 |
| Copper | 0.05 to 3.50 |
| Manganese | 0.3 to 5.0 |
| Molybdenum | 0.15 to 3.5 |
| Nickel | 0.20 to 35.0 |
| Niobium | 0.05 to 1.3 |
| Phosphorus | 0.01 to 0.03 |
| Silicon | 0.05 to 0.20 |
| Sulfur | 0.02 to 0.30 |
| Titanium | 0.002 to 0.04 |
| Vanadium | 0.03 to 0.25 |
Note 1—
Unless exceptions are noted, mass fraction ranges can be extended by the use of suitable reference materials. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 10.
