| Abstract: | In order to meet the performance requirements of drill bits in working environment of drilling rock,the steels for drill bits(45Cr,45CrNiMo1V,30CrNi3Mo) were taken heat treatments as 880 ℃ oil quenching and tempering in 580 ℃ oil colding.Then impacting fatigue test,tensile test and wear resistance test were taken for such steels.Through comparison,45 CrNiMo1V with superior comprehensive performance is used as threaded coupling column chisel bit steel for hydraulic drill vehicle. |
