The ductility map of 304HC stainIess was determinae by using the Gleeble-1500dy-namic thermal-mechanical simulator.The effect of Cu on the hot ductility of 304HC stainless steel was analyzed and the mathematical model of resistance to deformation was estoblished.The microstructur,inclusion and fracture surface wer studied by using the methad of microstructure analysis,scanning,eneryy spectrum and electron microscope.The results show that Cu has effect on the hot uctility,and the hot ductility of 304HC stainless steel decrease with the increase of content of Cu.The deformation temperature also has much effect on the hot ductility,the suitable defor-mation temperature are 1100-1200℃.The reason of it is that the Cu rich chemical compounds were precipitated from austenite phase during cooling.The Cu rich chem-ical compounds are brittle substance such as Cu2S,Cu2O and ε-Cu etc.

The plasticity map of 304HC stainless steel was determined by using tensile and compressive test. The effect of Cu on the hot plasticity of 304HC stainless steel was analyzed. The microstructure, inclusion and fracture surface were studied by using the method of optical microscopy, SEM, EDS and EPMA. The results showed that Cu has effect on the hot plasticity and the hot plasticity of 304HC stainless steel decrease with the increase of Cu content. The deformation temperature also has much effect on the hot plasticity, the suitable deformation temperature are 1100-1200℃. The reason is that the brittle compounds are Cu2S, Cu2O and PbCl etc.
