In the manufacture of steel _________ is used.
In the manufacture of steel _________ is used.
The correct option is B Manganese
Manganese is present in most commercially made steels. Manganese
plays a key role in steel because of its two important properties namely (i)
its ability to combine with sulphur (S), and (ii) its powerful deoxidation
capacity. Manganese is undoubtedly the most prevalent alloying agent in steels,
after carbon (C). Manganese is intentionally present in many grades of steel
and is a residual constituent of virtually all others.
Manganese has played a key role in the development of
various steel making processes and its continuing importance is indicated by
the fact that about 85 % to 90 % of all Manganese consumed in the world
annually goes into iron and steel making as well as in steel as an alloying
element. No satisfactory substitute for Manganese in steel has been identified
which combines its relatively low price with outstanding technical benefits.
