Abstract : Work is reported on the development of a high performance rocket motor case using 0.040 inch thick cold rolled and aged 18% nickel mar-aging steel strip. The material was vacuum melted and of the 250 composition. Higher strengths were obtained by the use of cold reduction of the strip before aging. The study was made to establish the required degree of cold reduction, to develop the welding schedules for the various joints of the assembly, and to establish the heat treating procedures for base metal, welds, and fabricated sections. This phase has been specifically designated for the fabrication of three, 20-inch diameter experimental rocket motor cases using the helically wrapped and welded design. (Author)
