GRADE D
3 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.
Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

Composition
| Element | Composition requirement |
|---|---|
| C | 0.7 ～ 1.3 |
| Mn | 11.5 ～ 14 |
| Ni | 3 ～ 4 |
| P | ≤ 0.07 (lower limit not stated) |
| Si | ≤ 1 (lower limit not stated) |
Applicability and limitations
A match in the materials database does not establish suitability for cold heading or guarantee finished-product strength. Confirmation must consider wire condition, deformation, heat treatment and tests on actual parts.
