ALLVAC 718 Plus Superalloy for Aircraft Engine Applications
ALLVAC 718 Plus Superalloy for Aircraft Engine Applications 79 still used in industrial turbines, but were later replaced by Waspaloy and Astroloy as stress and temperature requirements increased. These alloys were turbine blade alloys with a suitably modified heattreatment for discs. However, blade material is designed for creep,
ALLVAC 718PLUS, SUPERALLOY FOR THE NEXT FORTY YEARS
melting trials, ATI Allvac has developed a new alloy, Allvac 718Plus, which offers a full 55C temperature advantage over alloy 718 1214. The alloy maintains many of the desirable features of alloy 718, including good workability, weldability and moderate cost. The alloy
