The 146 in. dia metal case components of the Space Shuttle Solid Rocket Motor (SRM) being developed by Thiokol/Wasatch Division under Contract NAS8-30490 with NASA/Marshall Space Flight Center have been successfully static tested. The limitations placed on the program included current practice and facilities at the steel mills, forging suppliers, heat treaters, and machining operations. In addition, Thiokol had not previously fabricated metal components of this size with a fracture toughness of 90 ksi/sq in minimum. To ensure that the SRM was producible within the established guidelines, it was necessary to coordinate all data heat by heat, forging by forging, and heat treat run by heat treat run. The basic fabrication sequences are outlined, and the data from the heat programs are presented. (Kursetz)
