QSTE600TM steel Processing technology :
It should be taken into account during the design that the plasticity and formability of high strength steel for automobile decreases while strength increases. Also, the more springback and distortion should be taken into consideration during the design of die and parts when high strength steels are used. Besides, when High strength steels are sheared, improper shearing gap will cause a bad sheared edge and then cause the cracking during the formation. Poor shearing area will also be the source of fatigue cracking. Die or blade made up of inappropriate material will be easy to wear or even tipping.
