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.

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.
