Applicability and limitations

Historical procurement specification Acument AGT2282 January 2013, PDF page 6, Table 6.1; Heat composition wt%, condition AKFG. References for additional requirements outside the table and total residual content remain unresolved; displayed for reference only and excluded from limit-based reverse matching; Not guaranteed standard limits or heat-specific measurements.

Composition conditions

Historical procurement specification AGT2282 January 2013, Table 6.1/6.2 heat analysis, mass percent; This is not the original SAE text or a current controlled supply guarantee.
6.3 product-analysis tolerances reference ASTM F2282 and SAE J409 and must not be applied to the current heat analysis; Coatings, carburization and decarburization may affect product sampling.
6.5 specifies residual elements under ASTM F2282, with total residuals ≤0.35%; Referenced editions and residual-element definitions remain incomplete in this batch; the elements included in the total are not invented.
Composition outside the table separately references SAE J403/J404 (year not identified); Referenced conditions remain incomplete; displayed for reference only and excluded from limit-based reverse matching.
The AKFG condition entry is retained as in the original text; optional conditions are not merged into one steelmaking condition.
Unlisted elements and dashes are not filled with 0; one-sided bounds are not converted into fixed values.

Applicability and limitations

Original SAE J403 Revised JUN2014 Table 1 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 G10020 and SAE 1002 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. Table 1, note 3: where Cu is specifically required, Cu≥0.20% is usually specified; The residual options in this batch control residual content only; intentional Cu addition conditions are not unconditionally combined with residual maxima. The specific ordering range requires separate agreement; this special Cu condition is not assessed automatically. Table 1, note 4: this row must not be supplied as extra-low-carbon, IF-stabilized or unstabilized steel; A low C value does not override this restriction. 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.
