This article examines results of studies of the physico-mechanical properties of a tubular forging with dimensions of 2360 × 1690 × 5700 mm, a monolithic panel with dimensions of 5500 × 5500 × 300 mm, and a seamless bottom. The panel is obtained by reaming the forged tube, and the bottom is obtained by forging the panel on a 150-MN hydraulic press.
