Determination of Alloyed Elements in Special Steels by X-Ray Fluorescent Spectroscopy. III : Simultaneous Determination of Manganese and Chromium in Low Alloy Steels and Stainless Steels

Simultaneous determination of chromium and manganese in some low alloy steels and stainless steels was examined. The background correction method was applied to chromium K_α line and manganese K_β line. The equations for the correction of background were as follows : T_=C_-0.226C_/0.951 and T_=C_-0.219C_/0.951, where T is the true X-ray intensity and C is the observed X-ray intensity. Chromium and manganese in low alloy steels and in 25 per cent chromium -20 per cent nickel steels were determined with these equations and calibration curves
