Manganese Metal Lumps

Manganese is a silver-gray metal, much like iron, but softer than iron. If manganese contains a small amount of impurities-carbon or silicon, it becomes very hard and brittle. However, pure metallic manganese is not very widely used because it is more rusty than iron. In humid air, it becomes gray and loses its luster in a short while-a layer of manganese oxide is formed on the surface.

Product Features

Manganese is a metal with good activity, and its chemical properties are more active than iron. When manganese is added to molten steel, it can react with ferrous oxide to form oxide slag that is insoluble in molten steel and float on the molten steel surface to increase the oxygen content in the steel. reduce.
Although the deoxidizing capacity of manganese in molten steel is lower than that of other elements (such as calcium, aluminum, silicon), it is still very popular with steel companies because of its ease of production and relatively low price, especially for boiling steel. , Deoxidizing with ferromanganese alloy is an ideal deoxidizer.
Because manganese has a weak deoxidizing ability, it can adjust the oxygen content of steel, so that the oxygen will not be removed too much and it will not be able to boil. At the same time, the presence of manganese can also enhance the deoxidation capacity of silicon and aluminum, because the deoxidation product MnO and other oxides (such as SiO2) can form low-melting-point compounds which are beneficial to be eliminated from molten steel.

Application and After-Sales Service

1.In the iron and steel industry, metal manganese is mainly used for desulfurization and deoxidation of steel.
2.Manganese can be used as an alloy additive to improve the strength, hardness, elastic limit, wear resistance and corrosion resistance of steel.
3.In high-alloy steel, metallic manganese is also used as austenite compound element for making stainless steel, special alloy steel, stainless steel electrode, etc.
