Abstract

Residual stress analysis plays a vital role in determining the service life of a component subjected to adverse conditions like high temperature, high pressure and heavy load application. In this paper, residual stresses developed in the gate valve by depositing a stellite-6 hardfacing material were analyzed by Finite element simulation using contour method. The simulated values were verified by the experimental results measured at the surface of the hardfaced gate valve using X-Ray Diffraction technique. It was found that the residual stress values obtained by contour method had good agreement with the experimental XRD values. Also the developed residual stresses are less than the yield strength of stellite-6.
