Comparison of Stress to Produce 1% Creep in 1000 Hours in Sheet

At temperatures of 1200°F (649°C) and above, HAYNES® 263 alloy has creep strength less than those of two other gamma-prime strengthened alloys, HAYNES® 282® alloy and HAYNES® Waspaloy alloy.  At temperatures greater than 1300°F (704°C), HAYNES® 263 has a creep strength far superior to that of HAYNES® 718 alloy.
