     Nimonic90 process performance and requirements:

    1, the alloy in forging easily produce inside crack, allow hammer blow, don’t allow low temperature chamfering. Ingot outfit furnace temperature is not higher than 700 °C, 1150 °C ± final heating temperature 10 °C, open forging not below 1060 °C temperature, and forging temperature not less than 950 °C.

    2, the size of the average grain degrees of alloy forgings and deformation degree, eventually forging is closely related to the temperature.

    3, alloy in solid solution state can be inert gas protection electric arc welding and tungsten very flash butt weld.
