Abstract
In a method for heat treating alloy compositions within UNS N07028 the alloy composition is heated at a temperature between 1550° F. and 1750° F. for at least two hours, and then heated at a lower temperature between 1300° F. and 1550° F. for at least two hours. The alloy composition may be heated at a temperature between 1850° F. and 1950° F. for at least one hour before heating the alloy composition at a temperature between 1550° F. and 1750° F.
