Applicability and limitations
Table 2, high-manganese carbon steel SAE1526, UNS G15260, heat analysis wt%. Table 2 covers semi-finished forgings, hot-rolled or cold-finished bars, plate, strip, sheet and seamless tube. Wire rod is not listed in the heading, so suitability for cold-heading wire rod is not established. Si is not a universal mandatory constituent. When required, common bar or semi-finished-product options are ≤.10, .10–.20, .15–.35, .20–.40 and .30–.60%; wire rod additionally has .07–.15%. This record does not select a range without authorization. When Cu is required, ≥.20% is usually specified; this is not a universal Cu maximum or a default requirement. Addition of Pb .15–.35% requires the L designation and a change to UNS. Addition of B .0005–.003% requires the B designation and is not included in ordinary grades. Lower P/S for particular qualities or products requires separate verification under J411; agreed values from later years are not applied. Reporting additional elements does not establish universal limits in this table. Unspecified Si/Cr/Ni/Mo and other elements are not entered as zero. Product-analysis tolerances under J409 require separate verification.

Applicability and limitations
Original 2012 Table 1: ladle composition, mass fraction (wt%); applicability and deviations for product analysis must be checked separately under 4.3 and Table 5. Grade designations and product forms are retained as listed in the standard; cold-heading suitability is not implied. Note B: Si is an order-specific option; if not specified, it is unknown, not zero. Note C: Cu ≥0.20% applies only when ordered; no upper limit is invented, and ordinary orders do not automatically include Cu. Note D: Pb 0.15–0.35% applies only to an expressly designated leaded L grade; Pb is not added automatically to grades without L. Note F: additions of Bi/Ca/Se/Te are determined by agreement between purchaser and supplier; absent a specified value, they are not zero. Note E: boron treatment gives an expected content under specified conditions and is not a uniform B limit for all ordinary grades.

- 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.

Applicability and limitations
ASTM A29/A29M-2023 original Table 1: base entries are ladle-analysis mass fraction wt%; product-analysis tolerances are checked separately under 4.3 and Table 5, not added to ladle limits. Orders by Table 1 grade must meet its ladle limits under 4.1.1; other ordered chemistries are separately agreed under 4.1.2 and Tables 3/4 and must not be mixed into this table. General hot-wrought bar requirements do not, by chemistry alone, establish cold-heading suitability, supply or mechanical properties. Note B: the Si range is a common option only when required by the order; Si is unspecified by default, not a universal range or zero. Note C: Cu≥0.20% applies only when expressly required by the order and has no added upper limit. Note D: leaded steel Pb is 0.15–0.35%; retain L as part of the grade identity, not ordinary grades. If lead is added to the ladle stream, its cast or ladle-analysis value cannot be determined. Note F: Bi/Ca/Se/Te are specified by buyer-supplier agreement; do not enter zero when no value is given. Note E: only for expressly specified boron treatment of killed steel, expected B is 0.0005–0.003%; where usual Ti addition is not permitted, up to 0.005% may be expected. These are not mandatory B limits for all ordinary grades.

Applicability and limitations
Original SAE J403 Revised JUN2014 Table 2 cast or heat-analysis mass fractions wt%; Product-analysis tolerances are applied separately under SAE J409; J409 is not used to widen this table. UNS G15260 and SAE 1526 are names directly listed on the same row of this table; other standards or editions are not conflated with this edition. Where residual elements are not specified separately, the default is B; A/B/C is selected for the corresponding form or agreement; D has no tabulated limit, but the quantity of Cu/Ni/Cr/Mo must still be reported and is not treated as zero. To demonstrate compliance with the table, Cu/Cr/Ni/Mo/Si must be reported in addition to C/Mn/P/S; Below 0.02%, the original document permits reporting as <0.02%; this is neither a universal maximum nor zero. P/S conditions for flat and long products must be selected separately; the wider maxima must not be combined; 1006/1008 Mn is selected by form under Table 1, note 6/7. Si is specified only by agreement in the order; Common wire-rod options are ≤0.10, 0.07–0.15, 0.10–0.20, 0.15–0.35, 0.20–0.40 and 0.30–0.60%; The common 0.07–0.15 option is not listed for other products. Contract values must be checked against product form; no fixed Si is entered without agreement. Ordinary grades in this table do not automatically include Pb or B. Separately leaded or boron-treated grades require the L/B designation and the corresponding UNS; the original Pb0.15–0.35% and B0.0005–0.003% apply to that treatment condition and are not included in ordinary steel. The heading of Table 2 does not include wire rod, welded tube or sections; General table-note definitions or the RODS silicon option do not extend the product scope of Table 2. Residual A conditions for flat products require separate agreement; No value is provided for that condition in this batch, so it is excluded from selectable calculations and automatic reverse-matching branches. Long-product A and the remaining source-supported branches are retained separately. 3.1 and Table 6 require reporting of C/Mn/P/S/Si/Al/Cu/Ni/Cr/Mo/Nb(Cb)/Ti/V/B/N; As/Sb is additionally reported when requested by the purchaser. Si/Cu/Ni/Cr/Mo below 0.02% may be reported as <0.02%; Nb/Ti/V below 0.008% may be reported as <0.008%. These are reporting thresholds, not general composition maxima; they are not used to insert zeros or invent limits.
