Cast Iron and Cast
Steel
Dandong Foundry has produced cast iron
and cast steel for over 50 years. After
I joined this company, I started to
learn about some about iron and steel
castings, and start to write some
articles to share our experiences.
If you read this article, you must start
to study cast iron and cast steel for a
short time yet, so you must want to know
what is cast iron and cast steel, why we
use iron and steel castings, what are
the differences between them. Of course,
you may want to learn about their
prices. Please do not worry, let's start
to study these questions step by step.
What is cast iron and
cast steel?
Sometimes, we call cast iron as iron
casting. Cast iron parts are a kind of
iron parts. We melt pig iron into hot
liquid iron, and pour liquid iron into
heat-resistant molds, then after
cooling, we get the iron casting parts
which have a certain designed shape and
structure. The same method for cast
steel can make steel castings.
Why do we use cast
iron and cast steel?
Cast iron and cast steel can be made
into certain complex shapes, and they
have some good physical properties such
as
tensile strength,
elongation, heat-resistance,
wear-resistance etc. Sometimes, you can
not get these metal parts by welding and
forging methods. Moreover, you could
make very small or very large iron and
steel castings with high production
rate.
What are the
differences between cast iron and cast
steel?
The main difference between cast steel
and cast iron is the material,
specifically for the carbon content. The
cast iron has carbon over 2%, and cast
steel has carbon lower than 2%. Of
course, there are some small differences
with other composition, but the carbon
content is the main aspect.
The
prices
of cast iron and cast steel
Their prices are main affected by the
material and weight. The prices will be
higher if they have some alloys inside,
and the prices will be high if they are
heavier. Actually, the weight is the
base of their prices. If you want to
learn about the normal prices per ton
for cast iron and cast steel, you could
visit the website of
Dandong Foundry, we update
the prices on the website timely.
