The focus has been on providing a low cost alternative to alloys such as Waspaloy and Ren 233 41 while providing a nominal 50C 176 temperature capability advantage over alloy 718. As shown in Figure 1b, the 718Plus alloy lies in a composition range where the alloy is also anticipated to be readily weldable.
