SUP9A
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.

Applicability and limitations
POSCO local wire rod catalogue, PDF page 10
printed page 18, table index 2, row 4. The original edition number is not stated; the PDF creation date 2014-12-03 is not the standard publication year. Manufacturer range information does not constitute our supply guarantee. The spring-steel footnote on this page gives maximum Cu 0.30%, retained for the corresponding table.
Composition conditions
- Original catalog chemical composition table %, wire rod; Editions of JIS/SAE/DIN were not provided; catalog data shall not be upgraded to the verified official editions of these standards.
- Dashes are not zero; cast/product analysis types are not consistently explicit. Orders, product-analysis deviations and actual supply require separate verification.
- The maximum Cu for spring steel footnotes on this page is 0.30%, retained according to the corresponding table.
Verification notes
The original PDF tables and text coordinates were reconciled in both directions. Missing grade cells were restored; merged cells, footers and remarks were checked separately. Tables with identified disputes and rows without composition data are withheld.SUP9A · Nippon Steel Wire Rods EXE203 2008.3 / JIS G4801-2005

Applicability and limitations
Historical Nippon Steel wire-rod catalogue EXE203 2008.3, PDF page 11
printed page 18, JIS G4801-2005. The original catalogue does not explicitly identify the analysis type for this table. Manufacturer range data, not guaranteed standard limits or heat-specific measurements; this does not establish supply by Creation Group. Condition: original-table P/S ≤0.030; ≤0.035 may be accepted by agreement; no widening is applied by default; Only a minimum is given for B in SUP11A.
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.
- Original-table P/S ≤0.030; ≤0.035 may be accepted by agreement; no widening is applied by default; Only a minimum is given for B in SUP11A.
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.SUP9A · CHINA STEEL CORPORATION · Bars and Wire Rods Product Catalogue 2014-C1 / 7.1.12 JIS G4801 (Edition unspecified)

Applicability and limitations
China Steel bar and wire-rod catalogue CAT.NO.3-BD-01-2014-C1, PDF page 21
printed page 19, 7.1.12 JIS G4801 (edition not stated). 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. Condition: original-table P/S ≤0.030; by agreement, ≤0.035 is permitted; No widening is applied by default.
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.
- Original-table P/S ≤0.030; by agreement, ≤0.035 is permitted; No widening is applied by default.
