Purpose

This specification establishes testing methods and maximum permissible limits for trace elements in nickel alloy castings.

Application

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 tensile, stressrupture, creep, and low-cycle fatigue properties, but usage is not limited to such applications.

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.

Classification

This specification covers two classes of trace element control, defined by the elements to be controlled as follows:

Class 1 - Lead, Bismuth, Selenium, Tellurium, and Thallium

Class 2 - Lead, Bismuth, Selenium, Tellurium, Thallium, and Others (see 3.1.2)

Class 3 - Cancelled, use Class 1

Class 4 - Cancelled, use Class 2

When trace element control is required, the elements to be controlled shall be indicated by this specification number and a suffix number indicating the class. For example, AMS2280-1 indicates that control of lead, bismuth, selenium, tellurium, and thallium is required. If no class is indicated, Class 1 shall apply.
