ESR hollows 21 in. O. D. multiplied by 10 in. I. D. and 16 in. O. D. multiplied by 10 in. I. D. have been produced. The hot workability of both sizes was found to be excellent, based on Gleeble hot ductility studies as well as actual forging and rolling experiments. For the 21 in. multiplied by 10 in. ESR hollow, hot working studies indicate that 35% work is sufficient to develop a fully wrought structure. Initial mechanical property data are all above specification limits for the forged hollows.
