| Mn | 0.3 ～ 0.6 |
| P | ≤ 0.04 (lower limit not stated) |
| S | ≤ 0.04 (lower limit not stated) |
Applicability and limitations
Verify against the actual Japanese original Table 1 and normative Annex JA of JIS G3505:2017; heat analysis mass fraction wt%. The standard applies to mild steel wire rod for further processing into products such as iron wire and galvanized iron wire; electrode core wire rod is excluded.; Not automatically equivalent to special cold-heading steel. The applicable year is not specified for products on the website; The composition reference version for this item is 2017; this does not prove that the applicable year of the product contract has been confirmed. C and Mn for SWRM6/8 have only upper limits; unspecified lower limits shall not be added; Si and elements not listed in the table shall not be entered as 0; they shall not be intentionally added except for the purpose of finishing steelmaking; B addition by agreement shall follow JA.3. Add K to the end of the grade when killed steel is specified; K denotes deoxidation conditions; do not independently prescribe Al or Si content.. SWRM2/4 shall be adopted only per JA.1 agreement; SWRM17M/20M shall only have Mn changed to 0.60—0.90% per JA.2 agreement; the Mn range for ordinary 17/20 shall not be automatically expanded. When B is added per JA.3 agreement, B ≤ 70ppm, i.e., 0.007wt%; B content and B/N must be reported simultaneously. B/N for 2/4/6/8/10/12 is 0.4—1.8, and for 15/17/20/22 is 0.4—0.9. Compliance with the agreed conditions shall not be determined solely by satisfying the B upper limit; this upper limit shall not be applied if B is not agreed. The current composition table shows the default range without B addition; Agreed B/N must be verified separately in conjunction with the actual measured values of B and N for the heat; unspecified values for N shall not be entered as 0, nor shall B-suffix grades without original text basis be generated. Standard nominal diameters include 6.4mm; do not erroneously enter 6.5mm; Tolerances and diameter deviations for diameters > 25mm shall be per agreement; stricter precision per JA.4 must be separately agreed.
Verification notes
JIS G3505:2017, Table 1 and the JA low-carbon, high-manganese and deoxidation designations have been checked; Agreed addition of B requires separate verification of B/N.View associated products →SWRM12 · JIS G 3505-2004

Applicability and limitations
JIS G 3505:2004: clause 3/4 and main-text Table 1 of the Japanese original list SWRM12 mild steel wire rod; heat analysis, mass fraction wt%. Main-text Table 1 lists only C, Mn, P and S. Si is unlisted; values are not borrowed from another edition or treated as 0. Note to Table 1: when killed steel is specified, add suffix K, for example SWRM10K. K is an order-condition suffix; the eight grades are not all assumed to be killed steel by default. Annex 1/2 addresses special qualities and corresponding ISO conditions requiring agreement; informative or agreed provisions are not treated as default delivery guarantees. Historical edition 2004 is displayed separately and does not establish edition 2017 or current actual supply.
Verification notes
All eight rows in the original Japanese JIS G 3505:2004, main-text Table 1 were checked cell by cell; K is specified only as killed steelSWRM12 · POSCO wire rod catalogue (local archive 1203; original edition not stated)

Manufacturer range data, not guaranteed standard limits or heat-specific measurements; this does not establish supply by Creation Group. Condition: suffix K may be added for killed steel; individual K grades have not been created automatically.
Composition conditions
- Original catalogue mass percentages, historical manufacturer data from 2008.3; Referenced standard names and editions follow the original document; this does not establish that the official texts of those standards have been obtained and verified.
- A dash or blank must not be treated as 0; only chemical composition has been checked in this batch. Mechanical properties and actual supply require separate verification under the applicable conditions.
- A K suffix may be added for killed steel; individual K-suffixed grades have not been created automatically.
Verification notes
Grouped tables were expanded in full and checked against original images and notes. Ordinary, residual and conditional elements are kept separate; suffix tables lacking complete base-steel composition are excluded.SWRM12 · CHINA STEEL CORPORATION · Bars and Wire Rods Product Catalogue 2014-C1 / 7.1.5 JIS G3505 (Edition unspecified)
