Further Observations on A533-B Steel Plate Tailored for Improved Radiation Embrittlement Resistance.
Abstract
A series of advanced investigations on the radiation performance of four 6-in.-thick plates from a large (30-ton) commercial melt of A533-B steel is described. The melt represented the first commercial-scale demonstration test of improved radiation embrittlement resistance through the control (minimization) of selected residual impurity elements. Melt specifications emphasized a low copper and phosphorus content; one half of the melt was modified however by a copper addition (copper content increased from 0.03% to 0.13%). Initial plate tests described superior 550F (288C) radiation resistance, in terms of notch ductility retention, for the primary metl composition and verified the detrimental influence of impurity copper on irradiation behavior.
