Cast iron is a group of iron-carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities.
History:
Cast iron was invented in China in the 5th century BC and poured into molds to make ploughshares and pots as well as weapons and pagodas. Although steel was more desirable, cast iron was cheaper and thus was more commonly used for implements in ancient China, while wrought iron or steel was used for weapons.
The cast-iron is manufactured by re-melting pig-iron with coke and limestone. This re-melting is done in a furnace known as the cupola furnace. It is more or less same as the blast furnace, but it is smaller in size. Its shape is cylindrical with diameter of about 1 m and height of about 5 m.
The working of cupola furnace is also similar to that of blast furnace. The raw materials are fed from top. The cupola furnace is worked intermittently and it is open at top. After the raw materials are placed, the furnace is fired and blast of air is forced through tuyeres. The blast of air is cold as the impurities in pig-iron are removed by the oxidation

Difference of gray cast iron and ductile cast ironSearchnscore
Gray cast iron and ductile cast iron basically differ in the type or structure of the carbon contained in them. The making of cast iron is principally, liquefaction of iron by heating, followed by cooling and hence solidification. In case of gray cast iron, the making involves the addition of carbon in the heated beds where the liquefaction of base iron takes place. Whereas, for ductile cast iron, carbon as well as magnesium are added in the hot beds. These added components bind with the solid (cast iron) which is formed thereafter.

2. Overview of Engineering Cast Iron
Joseph Glanville wrote of cast iron, 'Iron seemeth a simple metal but
in its nature are many mysteries’. Many, but not all,of these mysteries
have been solved over the past three hundred years using the
combined skill of the foundryman and the knowledge of the scientist
to provide today's design engineer with a family of casting alloys that
offer a virtually unique combination of low cost and engineering
versatility.
The various combinations of low cost with castability , strength,
Machinability , hardness, wear resistance ,corrosion resistance,
thermal conductivity and damping are unequalled among all casting
alloys and It makes Cast Iron most widely used metal in engineering
purpose .
3. Definition
Cast Iron is generally defined as an alloy of Iron with greater than 2%
Carbon, and usually with more than 0.1% Silicon.
4. Types of Cast Iron
We can classified Cast iron in 4 major types depending on their
chemical composition of the iron, rate of cooling of the casting in the
mold (which depends on the section thickness in the casting),
types of graphite formed (if any) ~~
5. Gray Cast Iron
Gray Iron is by far the oldest and most
common form of cast iron. As a result, it
is assumed by many to be the only form
of cast iron and the terms "cast iron" and
"gray iron" are used interchangeably.
Gray Iron, named because its fracture
has a gray appearance, consists of
carbon in the form of flake graphite in a
matrix consisting of ferrite, pearlite or a
mixture of the two. The fluidity of liquid
gray iron, and its expansion during
solidification due to the formation of
graphite, have made this metal ideal for
the economical production of shrinkage-
free, intricate castings such as motor
blocks.
6. Properties of Gray Cast Iron
Graphite morphology and matrix characteristics affect the
physical and mechanical properties of gray cast iron.
o . Large graphite flakes produce good dampening capacity,
dimensional stability, resistance to thermal shock and ease of
machining.
o While on the other hand, small flakes result in higher tensile
strength, high modulus of elasticity, resistance to crazing and
smooth machined surfaces
Grey Cast Iron is highly resistant to rust, which is formed by the
reaction of oxygen and Iron. It is a perfect solution to avoid the
problem of corrosion.
Grey Cast Iron has low melting point – 1140 ºC to 1200 ºC.
7. Applications of Gray Cast Iron
Gray Cast Iron Can be used in producing heavy-duty machine tools,
bed, presses, high pressure hydraulic parts, frame, gears, bushings,
piston rings, cams, crankshaft, cylinder block, cylinder head, gear,
cylinder, base, bed, flywheel, cylinder liners, pistons, brake wheel,
gear boxes, pressure valve, coupling plate etc.

8. Applications of Gray Cast Iron
Brake Wheel Cylinder Block
Coupling Plates
Machine Tool
Hydraulic Casting Parts
9. Ductile Iron
Ductile cast iron is yet another type of ferrous alloy that is used as an
engineering material in many applications. To produce ductile iron, small
amount of magnesium is added to the molten iron, which alters the
graphite structure that is formed. The magnesium reacts with oxygen
and sulphur in the molten iron leading to nodule shaped graphite that
has earned them the name-nodular cast iron.
10. Properties of Ductile Iron
Strength higher than grey cast iron
Ductility up to 6% as cast or 20% annealed
Low cost
o Simple manufacturing process makes complex shapes
Machineability better than steel
Ductile cast iron offers significantly low shrinkage during casting.
Applications
Automotive industry are the major user of ductile iron castings.
o Crankshafts, front wheel spindle supports, steering knuckles,
disc brake callipers
Water pipe and pipe fittings industry.
12. Malleable iron
Unlike Gray and Ductile Iron, Malleable Iron
is cast as a carbidic or white iron and an
annealing or "malleablizing" heat treatment
is required to convert the carbide into
graphite. The microstructure of Malleable
Iron consists of irregularly shaped nodules of
graphite called "temper carbon" in a matrix
of ferrite and/or pearlite. The presence of
graphite in a more compact or sphere-like
form gives Malleable Iron ductility and
strength almost equal to cast, low-carbon
steel. The formation of carbide during
solidification results in the conventional
shrinkage behaviour of Malleable Iron and
the need for larger feed metal reservoirs,
causing reduced casting yield and increased
production costs.
13. Types of Malleable Iron
Depending on Annealing treatments we can get two types of
Malleable Iron –
Ferritic Malleable Cast iron
– Depends on C and Si
– 1st stage 2 to 36 hours at
940˚C in a controlled
atmosphere
– Cool rapidly to 750˚C &
hold for 1 to 6 hours
pearlitic malleable iron
– 1st stage 2 to 36 hours at
940˚C in a controlled
atmosphere
– Cool to 870˚C slowly, then
air cool & temper to
specification
14. Advantages
Excellent machinability
Significant ductility
Good shock resistance properties
Application
Malleable cast iron is used for connecting rods and universal joint
yokes, transmission gears, differential cases and certain gears,
compressor crankshafts and hubs, flanges, pipe fittings and valve
parts for railroad, marine and other heavy-duty applications.
Marine Hardware made by Malleable Iron
15. White Cast Iron
White cast iron is unique in that it is the only
member of the cast iron family in which carbon is
present only as carbide. Due to the absence of
graphite, it has a light appearance. The presence
of different carbides, depending on the alloy
content, makes white cast irons extremely hard
and abrasion resistant but very brittle.
It has lower silicon content and low melting point. The carbon present in
the white cast iron precipitates and forms large particles that increase
the hardness of the cast iron. It is abrasive resistant as well as cost-
effective making them useful in various applications like lifter bars and
shell liners in grinding mills, wear surfaces of pumps, balls and rings of
coal pulverisers, etc.
17. Effects of Alloying Elements on Cast Iron
Cast iron's properties are changed by adding various alloying elements
Silicon
After carbon, silicon is the most important alloyant because it forces
carbon out of solution. A low percentage of silicon allows carbon to
remain in solution forming iron carbide and the production of white
cast iron. A high percentage of silicon forces carbon out of solution
forming graphite and the production of grey cast iron.
Sulphur
Sulphur, when present, forms iron sulphide, which prevents the
formation of graphite and increases hardness. The problem with
sulphur is that it makes molten cast iron viscous, which causes
short run defects.
18. Effects of Alloying Elements on Cast Iron
Manganese
To counter the effects of sulphur, manganese is added because the
two form into manganese sulphide instead of iron sulphide. The
manganese sulphide is lighter than the melt so it tends to float out of
the melt and into the slag. The amount of manganese required to
neutralize sulphur is 1.7 × sulphur content + 0.3%. If more than this
amount of manganese is added, then manganese carbide forms,
which increases hardness and chilling, except in grey iron, where up
to 1% of manganese increases strength and density.
Nickel
Nickel is one of the most common alloying elements because it
refines the pearlite and graphite structure, improves toughness, and
evens out hardness differences between section thicknesses.
19. Effects of Alloying Elements on Cast Iron
Chromium
Chromium is added in small amounts to the ladle to reduce free
graphite, produce chill, and because it is a powerful carbide
stabilizer; nickel is often added in conjunction.
Molybdenum
Molybdenum is added on the order of 0.3–1% to increase chill and
refine the graphite and pearlite structure; it is often added in
conjunction with nickel, copper, and chromium to form high strength
irons.
Copper
Copper is added in the ladle or in the furnace, on the order of
0.5–2.5%, to decrease chill, refine graphite, and increase
fluidity.
