Abstract: The effects of final rolling temperature and cooling process after final rolling on the microstructure and mechanical properties of 65Mn hot rolled narrow strip were investigated by means of hardness test, optical microscopy and tensile test combined with continuous cooling transformation(CCT) curve of 65Mn steel. The results show that with the final rolling temperature rising, the grain size of 65Mn steel increased and the tensile strength and hardness reduced at the same cooling rate; with the increase of the cooling rate between final rolling and coiling, the grain size of 65Mn steel was refined and thus the tensile strength and hardness were improved at the same final rolling temperature and cooling rate after coiling; with the reduction of the cooling rate after coiling, the grain size of 65Mn steel was enlarged and thus the tensile strength and hardness were decreased at the same final rolling temperature and cooling rate between final rolling and coiling.
