1009

Table 1: UNS G10090 corresponds to SAE 1009; heat analysis, wt%. Si is not a universally mandatory constituent. When specified, common limits for bars/semi-finished products are ≤.10, .10–.20, .15–.35, .20–.40 and .30–.60%; wire rod also has the .07–.15% option. This record does not select a range without agreement. When Cu is required, ≥.20% is generally specified; this is neither a universal upper limit for Cu nor a default requirement. Addition of Pb at .15–.35% requires the L designation and a change to UNS; addition of B at .0005–.003% requires the B designation. These treatments are not included in ordinary grades. Lower P/S limits for certain qualities/products require separate verification against J411; agreement values from later editions are not imported. A requirement to report additional elements does not establish universal limits in this table. Unspecified Si/Cr/Ni/Mo and other elements are not assigned zero. Product-analysis deviations under J409 require separate verification.

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 G10090 and SAE 1009 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 5: this row may be supplied as extra-low-carbon, IF-stabilized or unstabilized steel; Specific stabilizing elements and delivery conditions require separate verification; alloy limits not listed in this table are not invented. 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.
