NPT Thread High Quality Black Malleable Iron Socket And Half Sockets

Gray cast iron – It shows a gray fracture surface consisting of ferrite and dispersed graphite flakes. The fracture surface appears gray because of the predominance of exposed graphite. When the composition of the iron and the cooling rate at solidification are suitable, a substantial portion of the carbon content separates out of the liquid to form flakes of graphite. The fracture path of such iron follows the graphite flakes. Gray cast iron is the result of stable solidification produced at slow cooling. It has several unique properties which are derived from the existence of flake graphite in the microstructure. It possesses high compressing strength, fatigue resistance and wear resistance. It is relatively soft and can be machined and welded easily. It has hardness conducive to good wear resistance. It resists galling under boundary-lubrication conditions. It has very good properties for use in vibration damping or moderate thermal shock applications. It is used for engine cylinder blocks, gears, flywheels, water pipes, brake discs, and machine tool structures etc.
