Silicon Manganese are mostly used in steelmaking and foundry
activities. Some
*0 % of the manganese used today in steelmaking is still used for
its properties as a deoxidant and a sulphide former. In this last
case it combines with sulphur avoiding the formation of iron
sulphides, which sulphides are low melting point phases which
become liquid at hot rolling temperatures and which, consequently,
generate surface cracking.
