Incoloy 800H round bar
ASTM B408
Incoloy 800H round bar supplies controlled-carbon, coarse-grain performance for creep duty to machined shafts, retainers and fastening parts. Diameter allowance and delivery condition determine the route from stock to the final loaded section.

Raw Material Specifications
Heat Treatment
Solution annealedThe specified solution treatment develops the controlled grain structure needed for sustained high-temperature creep duty.
What we can make in Alloy 800H
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 final solution-treated condition and grain-size requirement are recorded for the ordered H or HT grade. Final dimensions are inspected after the last thermal operation.
Finished geometry
Diameter, straightness, surface condition and cut length are checked against the stock order.
Where 800H fits — and what matters
Furnaces & Heat Treatment
Fixture pivots and conveyor shaftsIncoloy 800H 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 spindlesIncoloy 800H 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 rodsIncoloy 800H 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 800H 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.
