Metallurgy & Alloys
In metallurgical applications and alloys-making, manganese and all its compounds is playing as important roles like:
As deoxidizer
Manganese serves as a deoxidizer of the molten alloy, lowers the liquidus and solidus (thereby improving castability), and has a general strengthening effect.
As alloying agent
As an alloying agent, manganese improves strength, hardness, hardenability, and abrasion resistance. For example, Hadfield steel, containing 10 to 14 percent manganese, is a wear-resistant steel noted for its capacity to be work-hardened. In low-alloy steels, additions of up to 1.2 percent manganese, in combination with other elements, increases yield and tensile strength.
As desulfurizer
The sulfur content must be controlled during the steel-making process because high sulfur content in steel can easily cause thermal brittleness and reduce the mechanical properties of the steel. When manganese chemicals added as a desulfurizer, that will help to reduce the sulfur content in steel and improves the forgeability and rollability of steel.
As oxidant
In the hydrosmelting process of non-ferrous metals such as copper, zinc, cadmium and uranium, manganese dioxide is added as an oxidant to oxidize the divalent iron dissolved in the acid solution into trivalent iron. The pH value of the solution is adjusted to precipitate and remove the iron.
