Abstract：Three 403 steel bars of different compositions were searched, which were produced by 200kg VIM furnace and forged into 120mm. Mechanical and magnetic properties were tested after heat treatment 950-1000℃×1h OC+720-750℃×3h OC. The results show that, 403 steel bar with higher Ni or N has higher strength, magnetoconductivity and toughness especially. Compared with test steel bar with higer Ni, bar with higher N has higher magnetic induction in lower magnetic field intensity, while lower magnetic induction in higher magnetic field intensity. Strengthening mechanism was searched and the conclusion can be made to guide the production of this type steel for rotator.
