Applicability and limitations
Original Table 1, continued: SAE 8630 corresponds to UNS G86300; UNS is a search alias. Composition is heat analysis, mass fraction wt%; product-analysis deviations under SAE J409 require separate verification. Note 1: unspecified residual Cu≤.35%, Ni≤.25%, Cr≤.20% and Mo≤.06%; elements with specified alloy ranges follow the table ranges. Note 6: default P/S .030/.040; .030/.035 for flat products and .040/.050 for ASTM long products require selection by mutual agreement. Note 4: other Si ranges require agreement; no universal value is given. Note 5: addition of Pb at .15–.35 requires insertion of the L marker and is not included in ordinary grades. Note 7: elements subject to reporting do not necessarily have universal limits; reporting thresholds are not treated as zero. Composition alone does not establish cold-heading wire supply or forming suitability.

Applicability and limitations
Ladle chemical composition, mass fraction wt%; product-analysis deviations are specified separately in Table 6 and are not added to ladle limits. Table 2 Note 1: for Cu/Ni/Cr/Mo not specified as alloy ranges, the respective maxima are 0.35/0.25/0.20/0.06%; an explicitly specified alloy range takes priority. Note A: the purchaser may specify Si ≤ 0.10% as a separate condition from the tabulated Si range; the conditions are not combined. Note 4: Pb at 0.15–0.35% applies only to a separately specified L leaded grade; Pb is not added to ordinary grades. This is a general requirement for hot-worked bars; chemical composition alone does not establish cold-heading suitability or supply.

Applicability and limitations
Standard dated 2000-6, Table 1; ladle analysis, mass fraction wt%.; Product analysis deviations shall be verified separately according to SAE J409, and shall not directly expand the table values. Note 1: For elements neither specified nor required in the original table, residual upper limits apply: Cu/Ni/Cr/Mo respectively ≤0.35/0.25/0.20/0.06%; Explicit alloy ranges shall take priority. Pb 0.15–0.35% must be separately specified as L-grade; it is not automatically added to ordinary grades. Al, Ti, Nb, and V must be reported regardless of whether they are specified; Values below 0.008% may be reported as <0.008%; this is a reporting threshold, not a uniform composition upper limit. Grades with E prefix are electric furnace steels, with P/S upper limits of 0.025% respectively, separated from ordinary grades. Applicable to billets, slabs, plate, wire rod and hot-rolled/cold-worked bar products, among other forms.; Chemical composition itself does not guarantee suitability for cold heading.

- 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.
- Note residual limits Cu≤0.35, Ni≤0.25, Cr≤0.20 and Mo≤0.06 apply only to columns where these are not specified as principal elements; for starred grades 50B46/51B60, B 0.0005–0.0030% is an optional addition associated with the designation.

Applicability and limitations
Original ASTM A29/A29M-2023 Table 2: the basic table values are ladle-analysis mass fractions (wt%); product-analysis deviations must be checked separately under 4.3 and Table 6 and are not added to ladle limits. Under 4.1.1, an order for a grade in this table must meet its corresponding ladle limits; other ordered compositions are agreed separately under 4.1.2 and Tables 3/4 and are not silently mixed into this table. These are general requirements for hot-worked bars; chemistry alone does not establish suitability or supply for cold heading, or mechanical properties. Table 2 note 1: where no alloy range is specified, residual maxima are Cu/Ni/Cr/Mo 0.35/0.25/0.20/0.06%, respectively; ranges specified for the row take precedence. Table 2 note A: the purchaser may specify Si ≤0.10% as an alternative branch to the row’s Si range; the two are not combined. Table 2 note 4: Pb 0.15–0.35% applies only to a separately designated L grade. When lead is added to the ladle stream, its cast/ladle analysis cannot be determined; this does not automatically create a leaded grade or add Pb to ordinary grades.
