Grey Iron Casting - India
Why Grey Iron Casting ?
versatile of all foundry metals is the grey iron used in our casting. It
makes us proud to display an array of products we have in grey iron
castings and to give you more details regarding the type of work we can
do for you.
There are many reasons in choosing Grey iron than any other metal for
our castings. Grey iron has high carbon content which helps in
easy melting, casting and machining. Grey iron has very low degree of
shrinkage. Grey iron casting of any design can be made with ease because
of grey iron's high fluidity. By careful composition and selection of
grey iron for our castings we get a great degree of tensil and hardness.
Grey iron , though
being the cheapest of any ferrous material available, still has a number
of desirable characteristics not possessed by any other metal. Gray iron
is one of the most easily cast of all metals in the foundry. It has the
lowest pouring temperature of the ferrous metals, which is reflected in
its high fluidity and its ability to make grey iron casting in any
In many applications,
grey iron is just used in its as-cast condition, meaning that machining
is not required for the grey iron casting but Grey iron has better
machining qualities producing easily disposed of chips and giving a
clean surface with excellent wear characteristics. The resistance of
gray iron to scoring and galling with proper matrix and graphite
structure is universally recognized.
To avoid the general
claim that the life of a grey iron parts are short lived we carefully
check and apply higher strength and hardness grade of iron as required
for every specific casting. On the contrary one has to increase the
necessary strength and hardness only if required if not the grey iron
casting will become costlier and machining cost will increase through
lower machining rates. It is here that we put in our experience and
strike a balance to bring the best output.
It is surprising that
in spite of grey iron being an old material and widely used in
engineering industry, the metallurgy of the material has not been
clearly understood by many. Vasantham foundry is one of the few who have
understood and harnessed its potential.
Grey iron Casting - Foundry practice
properties of gray iron casting are not only determined by composition
but also to an extent influenced by foundry practice, particularly
cooling rate in the casting. All of the carbon in gray iron, other than
that combined with iron to form pearlite in the matrix, is present as
graphite in the form of flakes of varying size and shape. It is the
presence of these flakes formed on solidification which characterize
gray iron. The presence of these flakes also imparts most of the
desirable properties to gray iron. Though this information looks too
technical it is imperative that the grey iron casting foundries like
Vasantham understand its chemistry to some extent.
