Is the crankshaft material forged or ductile iron?
Other crankshafts are not clear about the car crankshaft. These two materials are useful, but the trend is to use ductile iron
Cast iron can not be forged, only steel, malleable iron can not be forged, only the crankshaft is particularly hot, can not meet the strength of the hardening when forging
Nodular cast iron, cast iron, forged steel crankshaft are used in the three. There are 3 kinds of axes in our company
