Incoloy 800 round bar

ASTM B408

Incoloy 800 round bar supplies heat and oxidation resistance for thermal equipment to machined shafts, retainers and fastening parts. Diameter allowance and delivery condition determine the route from stock to the final loaded section.

Heat Treatment

Annealed

Annealing reduces work hardening and restores ductility for the specified supplied condition.

What we can make in Alloy 800

Full-length round bar

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 round-bar blank

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.

Furnaces & Heat Treatment

Fixture pivots and conveyor shafts

Incoloy 800 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 spindles

Incoloy 800 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 rods

Incoloy 800 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.

Questions about 800 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.
