Abstract Two brands of high strength resisting corrosion steel bar containing Re, 20MnSiNbRe、20MnSiVNRe, wered studied in this paper. Their normal mechanical properties and microstructure were introduced. Salt spray accelerated corrosion test,alternate immersion test in laboratory, and metallic samples in seawater were emphasesed. The effects of Re on improving resisting corrosion of steel were discussed. Results showed that high strength resisting corrosion steel bar containing Re could accord with mechanical properties of HRB400 in GB 1499.2-2007
