What
type of steel is generally used for connecting rods, crank shaft and axle
components?
Mild
steel
Low
carbon steel
High carbon steel
Medium
carbon steel
Medium
carbon steel
●For
medium carbon steel, the carbon percentage varies from 0.3 to 0.8 %.
●These
steels have better strength and not very easy to shape as mild steel.
●The
hardness is slightly higher and ductility is poor.
●The
machine parts requiring strength like spring, connecting rod, axle, crankshaft,
dies for forging, etc. are made from medium carbon steel.
Hence,
the correct option is (D).
