in
modern
industry,
plays
a
crucial
role
in
shaping
our
daily
life.
But
how
is
each
type
of
steel
named? Typically,
the
name
of
a
steel
comes
from
its
chemical
composition
or
its
manufacturing
process.
For
instance,
the
well-known
stainless
steel
contains
at
least
10.5%
of
chromium,
which
gives
it
high
resistance
to
corrosion.
Meanwhile,
the
naming
of
carbon
steel
depends
on
its
carbon
content,
which
usually
ranges
from
0.30%
to
2.0%.
High
carbon
steel,
with
a
carbon
concentration
of
over
0.6%,
is
extremely
strong
but
brittle,
while
low
carbon
steel,
containing
less
than
0.25%
carbon,
is
softer
and
more
ductile. Apart
from
these
basic
types,
steel
manufacturers
also
add
other
elements
to
create
special
steels
with
specific
properties.
For
example,
adding
nickel
to
stainless
steel
makes
it
more
ductile
and
easy
to
weld.
Adding
molybdenum
to
high-strength
low-alloy
steel
enhances
its
corrosion
resistance.
Steel
names,
therefore,
often
contain
not
only
the
basic
type
but
also
the
added
elements
or
their
amounts. The
manufacturing
process
can
also
influence
the
naming
of
a
steel.
For
example,
cold-rolled
steel
undergoes
a
process
of
rolling
at
room
temperature
to
improve
its
mechanical
strength
and
surface
finish,
while
hot-rolled
steel
is
produced
at
high
temperatures,
yielding
a
rougher
surface.
Based
on
their
processing
methods,
these
types
of
steel
are
often
referred
to
as
CR
and
HR
steel,
respectively. In
conclusion,
steel
is
named
based
on
its
chemical
composition,
manufacturing
process,
and
added
elements.
Understanding
the
different
types
of
steel
and
their
names
is
important
in
various
industries
such
as
construction,
engineering,
and
manufacturing.
