MALLEABLE CAST IRON

MALLEABLE CAST IRON

 Introduction:-

Malleable iron is cast alloy consisting principally of iron and carbon, which is rendered tough and ductile by a control heat conversion process. It solidifies in the as cast condition in a graphite free structure, that is the total carbon contain is present in its dissolved and combined form as cementite. The properties of material are obtained by heat treatment. Since it can be easily caused to spread and flatten under pressure or hammering, it is known as malleable.

Properties:

1. It posses high yield strength, high Youngmodulus ,high impact strength,good ductility and mallaebility.
2. It possesses good wear resistance and vibration damping capacity.
3. It possesses good corrosion resistance,good machinability and castability.

Uses:

1. In automotive Industries.
2. In railroads.
3. For gear case.
4. Universal joint yoke.
5. Agriculture implements.
6. In construction and electrical equipments.
