Hastelloy X Properties, Data, and Metallurgical Characteristics 
A literature survey and testing program were 
initiated to obtain pertinent information for Hastelloy 
X through the temperature range of —423° to 1800°F. 
Hastelloy X is a nickel-base alloy with exceptionally 
good corrosion and oxidation resistance at tempera-
tures to 2100°F, superior strength, good resistance 
to a radiation environment, good fabricative qualities, 
and good notch-toughness. 
A report has been prepared which includes the ten-
sile properties of Hastelloy X forgings, strip, weld-
ments, and brazements. This information is presented 
as individual test data and as statistical means. The 
mechanical properties of shear strength, bearing 
strength, low-cycle fatigue, and thermal cycling are 
also presented. In addition, the manufacturing and 
fabrication processes are presented from raw material 
melting through fabrication of individual hardware 
components. Metallurgical analysis of thermal treat-
ments and processing are also provided, as are speci-
fic data on large heavy-wall forgings and thin strip.
