Heat Treatment

Alloy X-750 is austenitic under all conditions. The alloy is heat treated by several different methods depending upon the application or requirement. Two common treatments are:

1. For maximum creep, relaxtion and rupture strength at temperatures above 1100°F (593°C):

Solution Treatment - 1800°F (982°C), time commensurate with thickness, air cool.

Intermediate Age - 1550°F (843°C), 24 hrs, air cool.

Final Age -1300°F (704°C), 20 hrs, air cool.

2. For highest room temperature yield strength and tensile ductility:

Stress Equaliztation - 1625°F (885°C), 24 hrs, air cool.

Precipitation Age - 1300°F (704°C), 20 hrs, air cool.

Workability

The furnace temperature should be 2100°F (1149°C)-for optimal starting temperatures of 1950/2000°F. For service below 1100°F (593°C), higher strength can be obtained by combining some cold work with heat treatment because the effects are additive.
