Investigation of the conditions and effects of recrystalization of butane bottle sheets

Abstract

The critical amount of deformation was examinated in a steel sheet plate (c7 7216) for production propan-butan cylinders. It was found that it is 6%. The same experimental procedur was used to found this critical amount of deformation on the cylinder, ie. the possibility of apperance of great grain size during the recristolization process. It was examinated the influence of time of recristalization process to the ap­pereanrie of great grain size for critical amount of deforma­tion of 87, temperature of 695+5^°C.
