On cross correlation method for determining peak positions in X-ray stress measurement, two improvements have been put forward. Parabolic curve fitting at the crest part of the cross correlation function curve and coordinating manipulation for all peaks will increase the precision in peak position determination. The experimental results on super high strength steel 40SiMnCrNiMoV, high carbon steel T8 and Ni-based alloy GH39 showed that the error of peak position in cross correlation method was less than that in half-width method which is generally used.
