Made up of, vanadium microalloyed steels. Carbon steels, cast iron. carburization or nitridization can be used to harden it.
The crankshaft is the part of an engine which translates reciprocatinglinear piston motion into rotation. Crankshafts can be forged from asteel bar or cast in ductile iron. Today forged crankshafts are favored due to their lighter weight, more compact dimensions andbetter inherent dampening. Forged crankshafts can be made up of,vanadium micro alloyed steels. Other materials used are carbon steels,cast iron. Further carburization or nitridization can be used to hardenthe crankshaft surface.
