Applicability and limitations
Original SAE 52100 corresponds to UNS G52985; UNS is retained only as a search alias. ; Heat analysis wt%; Residual Cu≤.35%, Ni≤.25%, Cr≤.20% and Mo≤.06% are unspecified; explicit alloy ranges take precedence. ; Default and agreed P/S conditions are retained separately; Product-analysis tolerances under J409 require separate verification. ; Other Si ranges require agreement; Addition of Pb requires the L designation; ordinary grades do not include Pb. ; Required reporting of elements and reporting thresholds does not establish universal content requirements or zero content. ; Composition alone does not establish cold-heading suitability or supply availability. ; In this original-table row, all P/S are ≤.025%; Agreed widening for ordinary rows is not applied automatically.

Applicability and limitations
Heat analysis chemical composition mass fraction wt%; Apply product-analysis deviations under Table 6 separately; do not add them to heat-analysis limits.. Table 2 Note 1: Cu/Ni/Cr/Mo not specified as alloying ranges are allowed to be ≤0.35/0.25/0.20/0.06% respectively; Explicit alloy ranges shall take priority. Note A: The purchaser may specify Si≤0.10%, which shall be treated as a different condition from the Si range listed in the table, and the union of the two shall not be taken. Note 4: Pb is 0.15–0.35% only when lead-bearing steel designated L is separately specified.; Ordinary grades do not automatically include Pb. This standard provides general requirements for hot-worked bar products and cannot be used to commit to cold-heading suitability or supply based solely on chemical composition. Note B: Cu≤0.30%, Al≤0.050%, O≤0.0015% only when separately requested by the purchaser; Retain separately from the basic delivery conditions..

Applicability and limitations
Historical procurement specification Acument AGT2282 January 2013, PDF page 7, Table 6.2; Heat composition wt%, condition SKFG. 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 SKFG 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.

- Total residual elements ≤0.35%; the included elements and individual limits refer to ASTM F2282. The cited edition and residual-element scope have not been fully verified, so no automatic matching is made.

Applicability and limitations
Original ASTM A29/A29M-2023, Table 2: the basic table gives heat-analysis mass fractions wt%; Product-analysis tolerances require separate confirmation under 4.3 and Table 6 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. Table 2 Note 1: For elements where no alloy range is specified, the residual upper limits for Cu/Ni/Cr/Mo are 0.35/0.25/0.20/0.06% respectively; The alloy range specified in this row shall take priority. Table 2, Note A: The purchaser may specify Si≤0.10%; select this condition separately from the Si range in this row, without combining their ranges.. Table 2 Note 4: When L lead-bearing grades are separately specified, Pb is 0.15–0.35%; When lead is added to the ladle stream, its cast/heat-analysis content cannot be determined; do not automatically create lead-bearing grade records or add lead to ordinary-grade compositions.. Table 2 Note B: Cu≤0.30%, Al≤0.050%, O≤0.0015% only when separately requested by the purchaser; Do not include in the default base table range.
