HY N90 Material grades and equivalents

Nimonic 90/GB GH90/ UNS N07090 / BS Nimonic90/ W. Nr. 2.4632

HY N90 characteristics and application fields of summary:

This alloy is aging strengthen ni-based deformation high temperature ally, with a high amount of cobalt and many kinds of strengthening element, this alloy in 815 ~ 870 °C have high tensile strength and contravariance ability, good oxidation resistance and corrosion resistance, cold and heat alternately repeatedly in under the action of a higher fatigue strength and good formability and weldability. Used for turbine engine turbine dish, leaf, high temperature fasteners, card hoop, seals and elastic components etc.

 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.
