2 source records. Standards, editions and conditions are presented separately; matching grade names do not establish interchangeability.
Refer to each source for mass fractions and analysis type. Missing values are not treated as 0. Manufacturer typical values, standard guarantees and measured heat results must remain separate. Use the material selector for calculations and condition selection.

| Ni | ≤ 0.25 (lower limit not stated) |
| Cr | ≤ 0.2 (lower limit not stated) |
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
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.
