with hot rolling in laboratory and Gleeble hot simulator, the hot working of a hign nitrogen austenitic stainless steel (HNASS) has been researched. The results show that HNASS occurs dynamic recovery (DRV) and dynamic recrystallization (DRX) during hot working. All of them have well-defined stress peaks in flow curves at different conditions.During hot rolling experiment with temperature from 950℃ to 1050 ℃，test material did not take place recrystallization phenomenon until the deformation is up to 40%. Recrystallization influences remarkably the strength and ductility of material. Results show that test HNASS processes best strength combination with ductility.According to the curve of , the DRX critical strain of test material is determined. Also we calculate the activation energy of hot working with value of 746.5kJ/mol and attain the equation of hot working.
