| Abstract: | The influence of alloying elements V, Mo, Ni, Nb, Co and B on the structure and property of hot working die steel has been investigated by means of hardness test after quenching and tempering and by tensile test and impact test at room and high temperatures as well as by metallographic observation and TEM. It is shown that favorable strength and toughness of the steel can be obtained with suitable content of alloying elements. |
