摘要
45VB非调质钢具有优良的淬透性能,可保证半轴中频感应淬火淬硬层的均匀及层深,具有优良的抗疲劳性能;取消锻后预正火及校直工序,可提高零件质量、节省能源、改善劳动环境、降低半轴制造成本;可代替40MnB或40Cr制造CA141型汽车半轴,并可推广应用于其它中、重型载货汽车半轴的生产。
The untempered steel 45VB has the advantage that it has a good quenchability, for instance, axle shafts made of this material, after, intermidiate frequency hardening, the evenness and thickness of their hardened layers can be guaranteed. Also, it has favourable antifatigue property. Meanwhile as it is possible to cancel prenormalizing and straightening operations after forging, so the quality of workpieces has raised, energy saved, working environment improved and the manufacturing cost of axle shafts has reduced. Accordingly, it can be used to manufacture axle shafts for CA141 truck instead of steel 40MnB or 40cr, and it is worth spreading to manufacture axle shafts for medium or heavy-duty trucks.
