The properties of a large forged disc of S-816 alloy have been determined for both the as-forged and aged condition (disc NR-76B-F) and the heat-treated and aged condition (disk NR-76B-Q) at room temperature and, by means of stress-rupture and creep tests for time periods up to about 2000 hours, at 1200, 1350, and 1500 degrees F. Short-time tensile test, impact test, and time-deformation characteristics are included.
