P/M Rene 95 is a high strength, high temperature alloy used for rotating jet turbine components worldwide. It is one of the highest strength alloys available for service in the range of 800°F to 1200°F (425°C to 650°C). The alloy also provides excellent high temperature creep resistance and low cycle fatigue life. Tens of thousands of high pressure turbine disks and turbine blade retainers made from Crucible Rene 95 are in service on commercial and military airplanes and helicopters worldwide.
Advantages:
High Strength
Excellent high temperature creep resistance
Extended low cycle fatigue life

Supersolvus P/M Rene 95 provides even higher temperature creep and stress rupture resistance than standard Rene 95.
It is designed to provide even higher temperature creep resistance and stress rupture strength than subsolvus Rene 95. Chemistry is not modified. These properties are obtained by processing above the gamma prime solvus to provide a larger grain size than subsolvus processed Rene 95. Although this results in a small reduction in room temperature and elevated temperature strength, substantial ductility is maintained and considerably higher temperature service is possible. The primary use of supersolvus Rene 95 is for high pressure turbine blade retainers for high thrust aircraft turbines. This material can also be used for hot work tooling where ferrous based tool steels cannot maintain adequate strength.
Advantages:
Higher temperature creep resistance and stress rupture strength than standard
Rene 95
Larger grain size than standard Rene 95
