1132

Table 3A: SAE1132 corresponds to UNS G11320; heat analysis, wt%. Resulfurized/rephosphorized free-cutting steels: machinability characteristics do not establish cold-heading suitability, and no cold-heading product is added automatically. Addition of Pb requires the L designation and corresponding UNS. In this record, only 12L14 uses the explicitly listed Pb .15–.35%; other ordinary grades do not include Pb. Mandatory element reporting does not establish universal limits. Unspecified elements are not assigned zero; product-analysis deviations under J409 require separate verification. When Si is specified, common wire-rod options are ≤.10, .10–.20 or .15–.35%. Bars/semi-finished products follow the notes to Table 1; wire-rod ranges do not apply automatically.

2012 original text Table 1 heat analysis mass fraction wt%; The applicability and deviations of product analysis must be separately confirmed according to 4.3 and Table 5. Grades and product forms are retained as listed in this standard; suitability for cold heading is not automatically guaranteed. The Si listed in Note B is an option to be specified in the order; Unknown when unspecified, do not fill as zero. Note D only specifies Pb 0.15–0.35% for lead-bearing 'L' grades; Standard grades without 'L' shall not automatically include Pb. Note F: Additions of Bi/Ca/Se/Te are subject to agreement between the supplier and purchaser; do not enter zero when no value is specified..

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. The Si ranges in note B are common options when required by the order; Default Si is unspecified; neither a universal Si range nor zero may be assumed. 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.

SAE J403 Revised JUN2014 Table 3A: 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 G11320 and SAE 1132 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.
