Summary
This standard specifies the principle, instrumentation, working conditions and identification procedures for the identification of alloy structural steel grades by means of spectroscopic analysis. This section applies to the identification of alloy structural steels (including individual spring steels) listed in Table A.1. The types of alloying elements and their contents (ie, mass fraction) of the grades listed in Table A.1 are within the range defined by the strength of each corresponding element in this section, and may also be identified by reference to this section.
