Abstract: In order to study the tensile mechanical properties of stress corroded high strength galvanized steel wire with cracks,the mechanical model of high strength steel wire with cracks was established based on the data of stress corrosion test,static tensile test,electron microscope test and finite element simulation.The results show that in the static tensile test,the critical failure factor of the steel wire is the crack,and the stress concentration factor of the notch is much higher than that of the corrosion pit.The mechanical property change is caused by further corrosion of the initial crack.When corrosion  is serious,the mechanical properties is mainly determined by the crack and the corrosion pit.

Key words: high strength galvanized steel wire, neutral salt spray corrosion, crack, mechanical properties
