| Abstract: | For the difference of ship steel low temperature impact value, the effects of chemical composition, inclusion and microstructure of the refined and unrefined steel are analyzed. The results show that the refinement of steel can increase the impact resistance of steel, so the impact toughness was increased considerably to meet the reqirement of practical usage. |
