Hastelloy X Operational Domain

There are some notable limitations to this data. The 1% creep data for 10 5 hours was not available. The lOM hours creep data did not extend to the desired temperatures. The 1/3 UTS is roughly 195 MPa and the 0.2% offset yield strength was 245 MPa at 860 K. 

In all likelihood, all three limits are close to the same value at the expected operation temperature. The creep strength is constraint most likely to be exceeded Thermal Properties
