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.

| C | 0.25 ～ 0.31 |
| Mn | 0.6 ～ 0.9 |
| B | 0.0005 ～ 0.003 |
Applicability and limitations
P and S shall be selected separately according to flat products/long products; Upper limits cannot be combined. ; Si requires agreement at ordering: wire rod options are ≤0.10, 0.07–0.15, 0.10–0.20, 0.15–0.35, 0.20–0.40, 0.30–0.60%.; Other products have the same options as listed, except for 0.07–0.15. Fixed Si shall not be entered if not agreed. ; Residual elements Note 2: A Cu≤0.20/Ni≤0.20/Cr≤0.15/Mo≤0.06; B Cu≤0.35/Ni≤0.25/Cr≤0.20/Mo≤0.06 (default when not otherwise agreed); C Cu≤0.40/Ni≤0.40/Cr≤0.30/Mo≤0.12; Option D has no specified limits, but reporting is required.. Option A applies to flat products in grades ≤1060; other cases require agreement.. ; Note 3: For boron steels, insert B between the second and third positions, and change the last digit of the UNS to 1; B is 0.0005–0.003%.

chromium-vanadium-boron steels. The original catalogue does not explicitly identify the analysis type for this table. Historical manufacturer range data, not guaranteed standard limits or heat-specific measurements; this does not establish supply by Creation Group.
Composition conditions
- Historical manufacturer 2014-C1 catalogue, bars/wire rod; Where the referenced standard edition is not identified, a year is not borrowed from another catalogue; a catalogue is not upgraded to the official standard text.
- A dash or blank must not be treated as zero. Composition data do not establish completeness or applicability of a formula; mechanical properties and supply require separate verification.
Verification notes
Merged cells in all 28 catalogue tables were reconstructed geometrically, with no missing cells. Original images, continuation pages and notes are recorded; disputed conditions are withheld.10B29 · ASTM A29/A29M-2020

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.
