Vacuum are remelting (VAR) and electroslag remelting (ESR) processes for steam generator tubesheet forgings and tubing are to be used at the CRBR. It was found that there is essentially no significant effect on the uniaxial tensile properties of 2 1/4 Cr-1Mo steel by VAR or ESR. A summary is presented of results of a study of heat treatment combined with post weld heat treatment. It was found that regardless of the primary heat treatment, the post weld heat treatment plus in-service conditions will reduce the yield strength at elevated temperature below the Code Case expected minimum curve.
