    Abstract

    Twenty-two heats of low alloy steel were made to definite chemical compositions in order to study the effects of certain elements on temper embrittlement. It was necessary to confirm the composition of these heats by chemical or spectrochemical analysis by at least two different laboratories. This paper describes the chemical analytical procedures used for the analysis, the problems encountered in obtaining accurate and consistent results, and the solutions found for these problems.
