Choose the surface, section and dimensional tolerances that match your next machining or fabrication order.
As-rolled surfaces and dimensions specified for fabrication, further drawing or machining.
Choose cold-drawn or turned-finished material when the order calls for a brighter finish and closer dimensional control.
Specify diameter, end preparation, length tolerance and cut-piece quantity with your drawings.
Check the carbon and manganese ranges, then match the chemical acceptance limits to the edition specified in your contract.
| Element | Heat Analysis Range / Limit |
|---|---|
| Carbon (C) | 0.15–0.20% |
| Manganese (Mn) | 0.60–0.90% |
| Phosphorus (P) | ≤ 0.030% |
| Sulfur (S) | ≤ 0.035% |
Reference values follow SAE J403:2024. Confirm the requested specification and edition against the mill certificate.
| Supply Condition | Tensile Strength* | Yield Strength* |
|---|---|---|
