The developments of high strength materials for automotive engine moving system have become a critical issue due to the trend of high horse power and down-size engines. A crankshaft, in particular, is of importance because it rotates with experiencing more load as engine power and fuel efficiency are increased. Therefore, stiffness and durability of crankshaft is great concern for entire engine performance as well as life-time.In this study, High strength bainite steel has been developed, and its durability has been increased by 10% compared to conventional high strength steels but maintaining cost and produce ability are similar to those. Also, hardening mechanism and fatigue properties were investigated.
