Applicability and limitations
Table 3B SAE1215 corresponds to UNS G12150; Heat analysis wt%. ; Resulfurized
rephosphorized free-cutting steels; Machining performance characteristics do not prove suitability for cold heading forming, and cold heading products are not automatically added. ; The addition of Pb requires L identification and corresponding UNS; This record includes only the explicitly tabulated Pb .15–.35% for 12L14; do not merge this Pb addition into the data for other ordinary grades. ; Elements required to be reported do not equal uniform limits; Unspecified elements are not entered as zero; Product-analysis deviation under J409 requires separate verification. ; The 12xx series typically does not specify Si to avoid adverse effects on machinability; P/S is a bilateral range rather than only an upper limit.

China Steel Bar and Wire Rod Catalog CAT.NO.3-BD-01-2014-C1, PDF page 24/printed page 22, 7.1.17 SAE High Manganese/Free-Cutting Steels (edition not specified). 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: Si is selected by agreement; bar and wire-rod options are retained separately.; Ordinary grades in the original table shall not automatically include B addition. Cu is typically ≥0.20% when required; it is not the default Cu lower limit for all steel grades.
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.
- Si is an optional agreement condition, with separate options for bars and wire rod; B is not automatically added to ordinary grades. Where Cu is required, it is usually ≥0.20%; this is not a default Cu minimum for all grades.

Applicability and limitations
Original ASTM A29/A29M-2023, Table 1: the basic table gives heat-analysis mass fractions wt%; Product-analysis tolerances require separate confirmation under 4.3 and Table 5 and are not added to heat-analysis limits. When 4.1.1 is ordered by a grade in this table, the corresponding heat-analysis limits must be met; Other ordered compositions require separate agreement under 4.1.2 and Table 3/4 and are not merged into this table. General requirements for hot-worked bars; chemistry alone does not establish cold-heading suitability, supply or mechanical properties. Note D: Pb for leaded steel is 0.15–0.35%; L must remain part of the grade identity and is not included in ordinary grades; If lead is added in the ladle stream, its cast or heat-analysis content cannot be determined. Note F: Bi/Ca/Se/Te is specified by purchaser-supplier agreement; Unspecified numerical values are not entered as zero. The 4.3.2 product-analysis tolerance restrictions for P and S do not apply to resulfurized or rephosphorized/resulfurized steels; Product-analysis tolerances are not added to heat-analysis limits.
Verification notes
Existing OCR of the four-page, 190-row original 2023 table was parsed cell by cell. All values were screened for differences against independent 2012 data and checked against the original 2023 images and footnotes; no values were filled from the older edition.1215 · SAE J403-2014

Applicability and limitations
SAE J403 Revised JUN2014 Table 3B: original cast or heat analysis, mass fraction wt%. Product-analysis deviations are addressed separately under SAE J409; J409 is not used to widen this table's limits. UNS G12150 and SAE 1215 are names directly listed in the same row of this table; other standards or editions are not treated as this edition. Unless residual elements are otherwise specified, the default is B. A/B/C is selected for the applicable product form/agreement. No limit is listed for D, but the amount of Cu/Ni/Cr/Mo must still be reported; it is not treated as zero. To demonstrate table compliance, Cu/Cr/Ni/Mo/Si must be reported in addition to C/Mn/P/S. A value below 0.02% may be reported as <0.02% as specified in the source; this is neither a universal upper limit nor zero. Table 3A/3B covers forged semi-finished products, bars, wire rod and seamless tubes of free-cutting carbon steels; it is not presented as universal composition requirements for flat products. Retain the two-sided P/S range in this row. V0.04–0.08% for 11V41 is an explicit row requirement; ordinary 11xx does not include V. Si is normally not specified for 12xx to avoid impairing machinability. Unspecified Si remains unknown and must be reported under 3.1, not treated as zero. Pb is included only in the row for 12L14; ordinary 1212/1213/1215 does not include Pb. The identities L and UNS G12144 are retained. A free-cutting application does not establish cold-heading suitability; delivery, project-specific processing and supply require separate confirmation. 3.1 and Table 6 require reporting C/Mn/P/S/Si/Al/Cu/Ni/Cr/Mo/Nb(Cb)/Ti/V/B/N; As/Sb is also reported when requested by the purchaser. Si/Cu/Ni/Cr/Mo below 0.02% may be reported as <0.02%, and Nb/Ti/V below 0.008% as <0.008%. These are reporting thresholds, not universal composition maxima; they do not justify filling in zero or an unspecified limit.
