摘要：

This paper summarizes the. quality problems of the weldability of advanced vanadium modified Cr, Mo alloy steel material, during fabrication of reactor, pressure vessel being used for Refinery, Petrochemical, Chemical plants. Authors have focused on stress relief cracking occurred in weld metal and HAZ after stress relieving heat treatment of the weld. From the literature review, it appears that till date significant amount of efforts are made to understand the stress relief cracking, occurring in alloy steel. However considerable work is still being done on this quality issue to understand root cause of stress relief cracking and remedy to prevent it.
