What
is Ferro Alloy?
Steel
can roughly be grouped into two categories. Firstly there
is ordinary steel and then there is alloy steel. Alloy
steel is characterized by the presence of one or more
alloying elements. These alloying elements include silicon,
molybdenum, chromium, nickel, titanium, vanadium, niobium
and more. Upstream producers use these alloying elements
in their steelmaking in order to achieve the needed anti-corrosion
requirements as well as high temperature resistance and
high tensile strength in various segments of the steel.
In order to compartmentalize particular characteristics
of each alloy steel, varying the alloying element quantity
percentage in the steel production is the key and initial
method. Alloy steel has been used extensively in various
industries such as casting and foundries, forging, steel
pipe and tube, automobile ancillaries, construction and
aircraft components because of special features like reducing
the weight of a product or strong durability and high
strength.
