Define the actual steel and dimensional condition before selecting round bar for shaft manufacture.
Material request
SAE1045 appears in the title while detailed lists contain other structural carbon grades. Confirm actual chemistry and the applicable ASTM A29 requirements rather than assume equivalent shaft material.
Diameter and surface
The option is OD10–400 mm within a described 5–600 mm range. Confirm the requested 30–70 mm size and bright or polished surface, distinguishing it from black and pickled alternatives.
- Actual steel designation
- Measured bar diameter
- Rolled or cold drawn state
- Surface and straightness criteria
- Cut length and machining needs
Shaft acceptance
No hardness, tensile or precision shaft tolerance is supplied. Request material and dimensional records and define machining requirements rather than infer shaft performance or all grade and finish combinations from the broad bar listing.
