manganese


manganese
one of the most important constituents of steel in which it fulfils a number of functions. It acts as a mild de-oxidizing agent. It combines with the sulphur present to form globular inclusions of manganese sulphide which are beneficial to machining. It increases tensile strength and the hardenability of steel.
