Stability of properties: Alloy 617 exhibits good metallurgical stability for an alloy of its strength level. Table 7 shows changes in tensile and impact properties after exposures extending to 12,000 h at elevated temperatures. All samples were in the solutionannealed condition before exposure. The strengthening is attributable to carbide formation and, at exposure temperatures of 1200°F (650°C) to 1400°F (760°C), to precipitation of gamma prime phase.
