Forging conditions
Forging is made at a range of temperature included between 1150 and 950°C, then cooled at appropriate conditions for the final thermal treatment and obtain required characteristics. In any case, please contact us.
Properties / Main use conditions
This alloy is the "precursor" of refractory alloys with nickel base, it offers values to creeping until 800°C, together with an excellent resistance to corrosion at high temperature until 1100°C, especially in oxidizing ambiance.
Main applications
Gas turbines, flame tubes, components for heat treatment ovens.
