(R) Trace Element Control Nickel Alloy Castings.
|Publication Date:||1 November 2012|
This specification establishes testing methods and maximum permissible limits for trace elements in nickel alloy castings.
These products have been used typically for limited use to
achieve premium-quality material for highly-stressed rotating
parts, such as turbine blades, where control of trace elements is
required to maintain elevated-temperature
It is intended that this specification be invoked only for selected applications by stipulation on drawings, purchase orders, or other documentation supplementing the material specification or in material specifications.
