| Abstract: | This paper analyzes the differences of chemistry,inclusions and microstructure for refined and unrefined ship steels. Unrefined ship steel has higher sulfur and phosphorus contents and lower impact energy. It has more inclusions and band structure and easy to fracture. Refined ship steel has higher purity and lower sulfur and phosphorus contents, therefore, it has higher impact energy and good mechanical properties. |

| Keywords: | refining impact toughness inclusion band structure temperature fracture |
