WHITE CAST IRON

WHITE CAST IRON

Introduction:-

                        The broken surface of these types of iron shows a bright white fracture. It has no graphite and there fore white in colors. Hence the name white iron. The whole carbon content is in the form of cementite or lamellar pearlite. 

Properties: 

1. It has excellent abrasive resistance and it is extremely hard.
2. Under normal circumstances it is brittle and not machinable.
3. It retains hardness up to 550°C.
4. It has low ductility and low impart strenght..

Uses:

1. For manufacturing those components which require a hard and abrasion resistance materials.
2. For the production of malleable iron castings.
3. For parts of crushers, grinders, shot blasting nozzles, blades, and parts of pumps. Car wheels, metal working rolls, grinding rolls, pulverizes, clay mixing and brick making equipments, ploughs, rail wheels, brake shoes, dies, Muller wheels etc.
