The creep properties for the Hastelloy-X alloy which is one of candidate alloys for a high temperature gas-cooled reactor are presented. The creep data was obtained with different stresses at oC, and a number of the creep data was collected through literature surveys.

All of the creep data were combined together to obtain the creep constants and to predict a long-term creep by: 7. The predicted minimum creep rate showed a good agreement with the experimental data. At °C of the Hastelloy-X alloy, the creep curves, the creep rate, and the time to reach a limiting strain.

Without getting technical on this, the simple answer is Hastelloy C is a wrought material. Hastelloy is also a trademarked name for the material by Haynes International. CW12MW is an (almost) equivalent material in a cast form. Either sand or investment cast. Therefore, available creep, creep-rupture, and relaxation data for Hastelloy alloy X were collected and analyzed to yield mathematical representations of the behavior for design use.
