Heat Treatment
AnnealedAnnealing reduces work hardening and restores ductility for the specified supplied condition.
What we can make in Nimonic 75
Full-length bar
Use for repeated turning of shafts, studs and valve components from one heat-traceable stock length. Bar diameter must include machining allowance for the finished surface and straightness.
Cut blank
Use saw-cut blanks for short-run machining or forging starts. Cutting allowance and end squareness affect how much usable length remains after facing.

Supply & preparation
Cut lengths preserve the heat identity of the original bar. Turning or grinding allowance follows the required finished diameter.
Material condition
The ordered annealed or solution-treated state is retained in the lot record; forming and machining do not replace the specified thermal condition.
Finished geometry
Diameter, straightness, surface condition and cut length are checked against the stock order.
Where Nimonic 75 fits — and what matters
Furnaces & Heat Treatment
Fixture pivots and conveyor shaftsNimonic 75 round bar provides machining stock for fixture pivots and conveyor shafts, including turned shoulders, bearing seats and threaded ends. Bar diameter includes the allowance for finishing the final part. Hot dwell, thermal expansion and repeated furnace cycles set the working load.
Power & Turbines
Hot-duct linkage pins and damper spindlesNimonic 75 round bar provides machining stock for hot-duct linkage pins and damper spindles, including turned shoulders, bearing seats and threaded ends. Bar diameter includes the allowance for finishing the final part. Hot dwell and start-stop expansion act on the supported or moving component.
Chemical Processing
Reformer support pins and heater-fixture rodsNimonic 75 round bar provides machining stock for reformer support pins and heater-fixture rods, including turned shoulders, bearing seats and threaded ends. Bar diameter includes the allowance for finishing the final part. These parts work in the heated equipment zone, where sustained loading and thermal expansion govern their section and clearance.
Same round bar. Different material priorities.
Nimonic 75 material dataIncoloy 800HT
Tightly controlled carbon and Al + Ti for creep duty.
- Connection priority
- The mechanical requirement of the machined section
- N08811 material control
- 800HT tightens the 800-family chemistry around creep performance. Its solution-treated, coarse-grain condition and N08811 identity should remain linked through forming and final acceptance. At the machined diameter and cut surfaces of the future part, the relevant metal temperature can differ from the process or furnace set point.
Inconel 718
Precipitation-hardened strength for compact, highly loaded connections.
- Connection priority
- The mechanical requirement of the machined section
- Strength after aging
- Machine-stock properties and final aged properties describe different states. The final heat-treatment lot and mechanical results establish the strength available in the installed part. At the machined diameter and cut surfaces of the future part, the relevant metal temperature can differ from the process or furnace set point.
A-286
Aged iron–nickel alloy strength for hot bolting.
- Connection priority
- The mechanical requirement of the machined section
- Grade 660 class
- An ASTM A453 Grade 660 order includes its class and corresponding processing requirements. The alloy name A-286 alone does not identify that acceptance condition. At the machined diameter and cut surfaces of the future part, the relevant metal temperature can differ from the process or furnace set point.

Questions about Nimonic 75 round bar
Is the bar condition the same as the finished-part condition?
Not necessarily. A solution-treated or annealed blank may be selected for machining before a specified final treatment. Stock and finished-part mechanical records need to identify the conditions they represent.
