Abstract

Cold work enhances the room temperature tensile properties of austenitic stainless steels. There are few data on the effect of varying degrees of cold work on elevated temperature properties. Such information is needed to set design limits on the use of cold-work enhanced properties in the creep range. ASTM A-193 B8 bars were given three levels of cold work. Tensile properties, creep-rupture properties, and the resulting microstructures were determined and compared with those of annealed bar. There is a temperature limit, dependent on the degree of cold work, beyond which the enhancement of creep-rupture properties is not observed.
