Abstract : The program for acquisition of mechanical properties selected 3-1/2-in. plate as the thickness to be evaluated since this thickness, at the reported material strength, would be required for a 20,000-ft operating depth submersible. For proof of fabricability the program included manufacture and depth testing of a subscale spherical pressure hull to illustrate material formability, weldability, and suitability of the weld quality for deep submergence service. As a step leading to Category 2 classification, the program also included explosive bulge testing of 2-in. plate weldments in conformance with NAVSHIPS 0900-005-5000. (Author)
