    SEM,optical metalloscope and mechanical property test were employed to investigate 516Gr70 steel plate with unaccepted impact property.The experimental results indicate that the non-homogeneous grain size and bainite microstructure in the steel lead to undesirable impact property.After heat treatment,the impact property of the steel improves.
