Medium-Carbon---Wrapped Steel Bushing
This category provides well-balanced comprehensive mechanical properties and can be strengthened through heat treatment. It usually requires surface carburizing and quenching to enhance surface hardness and wear resistance, making it suitable for applications with moderate loads.
