The mechanical properties parameters of hardened stainless steel used for large thin-walled parts at the bottom of rocket box were obtained by single pull test.The structural characteristics of thin-walled curved parts are analyzed.the drawing process parameters were established by analyzing the structural char-acteristics of thin-walled curved parts. the influence of springback compensation coefficient on the forming stick degree was studied.theoretical basis and practical experience for practical production is provided by the application of the springback compensation coefficient of stretching forming process.And it has far-reaching guiding significance for the mass production of this kind of hardened stainless steel thin-wall curved parts
