Abstract:

An experimental program was conducted to establish the feasibility of manufacturing ultrahigh strength rocket motor cases by stretch forming preforms constructed of 301 stainless steel sheet at -320 F. Experimental cases were produced which achieved 260,000 psi nominal ultimate strength at room temperature. It was demonstrated that close dimensional control of cylindrical cases could be obtained by stretch forming in a die. Process controls were established for the fabrication of preforms. The dependence of material cryogenic properties and weldability on composition was observed, and material specifications were established. Some preform and die design parameters were investigated and established experimentally. Author
