4.Characteristics
Age hardening special nickel-based alloy, high effective strength in 1400-1600°F.
Good resistance to oxidation used in gas turbine engine at 1400-1600 ° F atmosphere.
In 1150-1150 ° F, Waspaloy creep rupture strength is higher than in 718.
On a scale of 0-1350 ° F , hot tensile strength for a short period of time is worse than 718 alloy.
5.Applicatiopns
1.The chimney pipes;
2.Fasteners.
