What changes when 1144 Steel is ordered at 1-1/2 in
A medium-carbon free-machining steel widely used for shafts and machine components that need more strength than low-carbon screw-machine grades. At 1-1/2 in, the RFQ should treat grade, diameter, condition, finish, usable length, quantity, documents, and delivery as one purchasing description.
Commercial 1144 and proprietary stress-relieved products are not automatically identical. State the required condition, mechanical properties, straightness, finish, and source restrictions. At this larger diameter, bar weight, machine capacity, loading, saw route, bundle handling, and freight can materially change the practical sourcing plan.
Nominal size is only the starting point. State the acceptable incoming diameter range, roundness or ovality requirement, straightness, surface finish, and inspection method whenever those variables can affect the guide bushing, collet, unattended run, or final part.
Approximate bar weight and quantity planning
The planning weight for 1-1/2 in 1144 Steel is approximately 6.014 lb/ft. This is an estimate for quoting and handling—not a certified shipping weight.
| Nominal length | Approx. weight per bar | Planning use |
|---|---|---|
| 36 in | 18.04 lb | Feeder or magazine planning |
| 48 in | 24.06 lb | Feeder or magazine planning |
| 72 in | 36.09 lb | Feeder or magazine planning |
| 144 in | 72.17 lb | Full-length or conversion planning |
Actual weight varies with diameter tolerance, density, cut-length tolerance, and count. Confirm bundle size, piece count, carrier limits, and the usable length range before release.
Cut-length and machine-fit plan
Do not treat 36, 48, 72, or 144 inches as universal standards. State the machine and feeder, usable minimum and maximum length, remnant strategy, end squareness or chamfer, burr limits, packaging orientation, and whether pieces must remain segregated by heat or lot.
For repeating programs, record actual incoming maximum and minimum diameter, heat identity, hardness where relevant, and observed machining behavior. That evidence is more useful than assuming every heat or commercial finish will run the same.
How to specify this exact requirement
- 1144 Steel / UNS G11440
- 1-1/2 in nominal diameter plus the required incoming tolerance
- Condition, hardness, finish, straightness, and surface requirements
- Usable or cut length, end condition, quantity, destination, and need-by date
- Governing specification and revision, requested MTR/CoC, heat-lot, origin, traceability, and no-substitution flow-downs
