Summary
This standard specifies the method principles, instruments, working conditions and identification steps for identifying high-temperature alloy grades with nickel as the main alloy element using spectrum analysis methods. This standard is applicable to the identification of various nickel-based high-temperature alloy grades listed in Table A.1. Various nickel-based high-temperature alloy grades other than those listed in Table A.1, as long as the types of alloying elements are within the range of the types of elements listed in Table A.1, and the content (i.e., mass fraction) of the alloying elements is within the corresponding range of this standard. The element content determination intensity standard can be used as a reference within the range defined.
