Abstract：

The influence laws of initial billet temperature on the DRX volume fraction and the average grain size （Daverage）during 304 austenitic stainless steel four valve body extrusion process were investigated based on Deform-3D software. The initial billet temperature was optimized to obtain the fine grain and improved structure，and the optimized initial billet temperature about 1160-1220℃ was got. Finally, the correctness of the optimized results was verified by experiments.
