对非调质钢 1 2 Mn2 VBS与调质钢 45、40 Cr进行了切削加工性能对比试验 ,试验得出的结论为 :1 2 Mn2 VBS钢有更好的切削加工性能 ,用其制造汽车前轴及转向节比用后者更能节省刀具 ,更有利于劳动生产率的提高。
The non-quenched and tempered steel 1 2 Mn2 VBS and quenched and tempered steel 45, 40 Cr machinability comparison test, the test concluded that: 1 2 Mn2 VBS steel has better machinability, with its manufacture of the car before Shafts and steering knuckles save more tooling than the latter, which is more conducive to the improvement of labor productivity.
