DEVELOPMENT OF DEEP DRAWN - ONE PIECE HIGH PERFORMANCE ROCKET MOTOR CASE
Abstract
Estimated delivery schedules are presented for the special tooling (dies and punches) required for the production of the deep-drawn 40-in.-diam rocket cases. Evaluation data for the process annealing and cold reduction of 20 and 25% Ni steels are also presented. The 20% Ni was annealed at 1500 F for 1 hr and the 25% Ni at 1600 F for 1 hr. No fractures were noted after 6 reductions of 30.5 to 34.5% on the 20% Ni, and 6 reductions of 26 to 29% on the 25% Ni alloy. Preliminary attempts were made to deep draw the 20% Ni alloy on the sub-scale (2-in) tooling. The results indicated that it is feasible to cold draw the material.
