| Element | Composition requirement |
|---|---|
| C | 0.39 ～ 0.46 |
| Si | 0.15 ～ 0.35 |
| Mn | 0.6 ～ 0.9 |
| P | ≤ 0.03 (lower limit not stated) |
| S | ≤ 0.03 (lower limit not stated) |
Applicability and limitations
Based on the official Japanese original text of Tables 1/2 and Normative Annex JA of JIS G3506:2024; Heat analysis, mass fraction wt%. Applicable to wire rod intended for further processing into hard-drawn steel wire, oil-quenched and tempered steel wire, prestressed concrete steel wire, galvanized steel strand, steel wire rope, etc.; This standard does not include wire rod for piano wire and wire rod for bridge cables. Cannot be automatically regarded as applicable for cold heading or as a supply guarantee by the company. The default chemical ranges in Table 2 are separate from the narrowed C ranges in JA.1 adopted only by agreement between supplier and purchaser: the upper and lower limits of the agreed range are narrowed inward by 0.01 percentage points each, and are not adopted automatically by default. Alloying elements not listed in Table 2 shall not be intentionally added except for the purpose of finishing steelmaking; Unspecified values shall not be filled as zero, nor shall the complete carbon equivalent be calculated based on this. Clause 9 generally does not specify fixed mechanical properties. Verification shall be performed according to JA.3/JA.4 only when a target tensile strength has been agreed upon and the corresponding agreed delivery condition is adopted; The ±100/±120MPa in Table JA.1 are allowable deviations around the agreed target, not the absolute Rm range, nor a substitute for the target value. Clause 7.1 specifies an average total decarburization layer depth ≤0.20mm; JA.2 may be tightened to ≤0.15mm by agreement. Average total decarburization depth is not the maximum depth of a single field of view; whether to adopt the agreed value must be confirmed separately. Austenitic grain size and non-metallic inclusion limits must be specified by the purchaser and confirmed by agreement under 7.2; a rating cannot be assigned automatically from the grade alone. Table 3 standard diameters are 5.5, 6, 6.4, 7, 8, 9, 9.5, 10, 11, 12, 13, 14, 15mm; Table 4: for diameters ≤15mm, the tolerance is ±0.40mm and the out-of-roundness is ≤0.64mm; For >15mm, agreement is required; do not extrapolate. Inspection, sampling, dimensions, surface, and other product standard conditions shall be verified separately; The relationship with the ISO 16120 series is one of modified adoption, which does not equate to automatic interchangeability of grades.

Applicability and limitations
JIS G 3506:2004: clause 3/4 and Table 1 of the English original list SWRH42B high-carbon steel wire rod. This record gives heat analysis, mass fraction wt%, from historical edition 2004, separately from edition 2024; current supply is not assumed. The note to Table 1 permits narrowing each end of the C range by 0.01 percentage points only by mutual agreement; the default range is not narrowed automatically. Clause 5.1: average total decarburization depth ≤0.20mm; inspection may be omitted unless specifically requested by the purchaser. Agreed special-quality, grain-size and inclusion requirements require separate verification. Wire rod under this standard is not automatically equivalent to cold-heading wire or a guarantee of finished-product properties.
Composition conditions
- Table 1 default C range as above; Narrowing of C upper and lower limits by 0.01 percentage points each is adopted only by mutual agreement.
- 5.1: mean total decarburization depth ≤0.20mm; this inspection may be omitted unless specifically requested by the buyer.

The historical translation was checked row by row; the official Japanese original is still missing. Reference-review status is retained, without claiming original-source verification or current supply. Note to Table 1: narrowing each end of the C range by 0.01 percentage points requires agreement between purchaser and supplier. Clause 4.1: average total decarburization depth ≤0.20mm, but testing may be omitted unless requested by the purchaser. Grain-size and inclusion limits are subject to agreement.
Composition conditions
- Narrowing each C limit inward by 0.01 percentage points applies only by agreement; the default range is not narrowed.
