Abstract Influence of alloy components on mechanical properties, microstructure and precipitation of second phase particle of bridge steel plate of HPS70W has been studied by the addition of different content of Nb、Mo、V. The results show that alloy element Mo and V have little precipitation strengthening effect on bridge steel plate of HPS 70W, but alloy element Nb has obvious effect on low temperature toughness, strength and ductility of bridge steel plate of HPS70W.
