Abstract： Effect of strain rate on room temperature tensile properties of 10Ni5CrMoV hull steel was investigated at the strain rates between 1.6×10-31.2×103s-1.The experimental results show that strain rate doesn’t affect the fracture mechanism of intragranular dimple and mainly dislocation slipping；the tensile strength is increased slightly along with the increase of strain rate，however，the elongation doesn’t decrease in general which is decreased firstly and raised later with the increase of strain rate，the high strain rate doesn’t embrittle the 10Ni5CrMoV steel.The experimental results can be explained by dislocation slipping.
