| Abstract: | The mechanical property at various heat treating systems and low temperature serial impact test of low alloy high strength structural steel SM570 are described. The microscopic structure, inclusion and crystalline grain size of the steel are inspected and analyzed. The result indicates that properties of SM570 steel plate meet the standards, low temperature impact toughness, in particular, is better. |
