Description / Abstract:
This SAE Aerospace Standard (AS) establishes the requirements
for AS3504 and AS3505 thin wall self-locking inserts made from a
corrosion and heat resistant, age hardenable nickel base alloy of
the type identified under the Unified Numbering System as UNS
N07718.
Classification
Tensile strength at room temperature 185 ksi minimum. Maximum
test temperature of parts is 1025 °F.
The method of locking the insert into parent material to resist
rotation to be by means of swaging the insert knurled collar into a
hole prepared in per AS3508.
Application
Primarily for use in aircraft engines application up to
approximately 1025 °F where an insert with a self-locking feature
is required at elevated temperature, having excellent tensile
strength and resistance to relaxation.
