SCOPE
5、: 1.1 Purpose: This specification establishes maximum permissible limits for elements not normally specified but which may occur in trace amounts in wrought nickel, cobalt, and iron alloy products. 1.2 Application: Control provided by this specification has been used typically for highly-stressed ro
6、tating parts, such as turbine discs, where control of trace elements is required to maintain elevated-temperature tensile, stress-rupture, creep, and low-cycle fatigue properties, but usage is not limited to such applications. 1.2.1It is intended that this specification be invoked only for selected
7、applications by stipulation on drawings, purchase orders, or other documentation supplementing the material specification, or in material specifications.

9、8.2), defined by the elements to be controlled as follows: Class 1 Lead, Bismuth Class 2 Lead, Bismuth, Selenium Class 3 Lead, Bismuth, Selenium, Silver, Tin Class 4 Lead, Bismuth, Selenium, Silver, Tin, Thallium, Tellurium, Arsenic 1.3.1When trace element control is required, the elements to be con
10、trolled shall be indicated by this specification number and the appropriate class number. For example, AMS 2281A, Class 1 will indicate that control of lead and bismuth is required. 2. APPLICABLE DOCUMENTS: The issue of the following documents in effect on the date of the purchase order forms a part
