SNB7
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.

Carbon-equivalent reference
Estimates are presented separately for each applicable composition condition. Match the actual ordering conditions; ranges must not be combined.
Applicable diameter ≤90mm, C .38–.48%
90 < diameter ≤120mm; Table 3, note b permits a C maximum of .50%; Use of this option must be confirmed
Composition record (conditional branches apply; this is not an unconditional requirement)
| Element | Composition requirement |
|---|---|
| C | 0.38 ～ 0.48 |
| Si | 0.2 ～ 0.35 |
| Mn | 0.75 ～ 1.0 |
| P | ≤ 0.04 (lower limit not stated) |
| S | ≤ 0.04 (lower limit not stated) |
| Cr | 0.8 ～ 1.1 |
| Mo | 0.15 ～ 0.25 |
Applicability and limitations
Composition based on JIS G4107-2007; the product edition is unspecified, so confirm the edition applicable to the contract.
Composition conditions
- Table 1/3 and Clause 5 of the official Japanese text of JIS G4107:2007; heat-analysis mass percentages.
- Applicable for diameter ≤120mm; For SNB7 diameter >90mm, the C upper limit of 50 may be adopted per Table 3 Note b, as an independent selection.
- SNB5 original text C≥.10% specifies only a lower limit; do not fabricate a carbon upper limit or a complete carbon equivalent upper limit.
- Elements not specified in the table shall not be intentionally added without agreement between both parties, except additions needed to finish steelmaking; A blank must not be assumed to represent zero.
- Product analysis tolerances shall be per JIS G0321 Table 4, not mixed with heat analysis values.
- Alloy-steel bolt materials for high-temperature service, including bars and wire forms; Cold heading processes and actual supply conditions are still to be verified separately and have not been automatically added to the product center.
