Grain size control

Inconel alloy 625 —Low-cycle fatigue resistance has been increased from 70-80.000 to 110-120,000 psi at 10 cycles. This has been achieved through grain size control and improved product cleanliness. Major applications are bellows and expansion joints.

For a given alloy composition, the final property adjustment by work hardening and grain size control is of particular importance for the production of semifinished material like sheet, rod, tube, and wire. This is achieved either by a final cold-working step, starting from a soft-annealed state, and...
