1 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.

Purchaser specifies Si≤.10%
Composition record (conditional branches apply; this is not an unconditional requirement)
| Element | Composition requirement |
|---|---|
| C | 0.48 ～ 0.53 |
| Mn | 0.75 ～ 1.0 |
| P | ≤ 0.035 (lower limit not stated) |
| S | ≤ 0.04 (lower limit not stated) |
| Si | 0.15 ～ 0.35 |
| Ni | ≤ 0.25 (lower limit not stated) |
| Cr | 0.8 ～ 1.1 |
| Mo | 0.15 ～ 0.25 |
| Cu | ≤ 0.35 (lower limit not stated) |
Applicability and limitations
Original header A322–91(Reapproved2001)e1; note e1 records correction of Table 1 in year 2004, month 5. The full edition is retained, not represented as 2013/2024. Cast analysis wt%. Note A gives maximum incidental contents for elements not otherwise specified or required: Cu≤.35/Ni≤.25/Cr≤.20/Mo≤.06; explicitly specified alloy ranges take priority. Note F: the purchaser may specify Si≤.10%, usually for severely cold-formed parts; default Si .15–.35%. Select the two conditions separately; this does not establish cold-heading supply availability. Note B: adding Pb .15–.35% requires L identification; not included in ordinary grades. This standard covers hot-worked alloy steel bars; coiled dimensions and applicability require supplier confirmation. Product deviations and other composition agreements referring to A29 require separate verification. Original-table UNS G41500; grade column 4150.
