Alloy steel
is steel alloyed
with other elements
in amounts of between
1 and 50% by weight
to improve its mechanical
properties. Alloy
steels are broken
down into two groups:
low alloy steels
and high alloy steels.
Low alloy steels
are defined as having
an alloy contents
between 1 and 4%
and high alloy steels
have 4 to 50% alloying
contents.[1] However,
most commonly alloy
steel refers to
low alloy steel.
These
steels have greater
strength, hardness,
hot hardness, wear
resistance, hardenability,
or toughness compared
to carbon steel.
However, they may
require heat treatment
in order to achieve
such properties.
Common alloying
elements are molybdenum,
manganese, nickel,
chromium, vanadium,
silicon and boron.
