It cannot be bended or cut because it is too much brittle. Physical Properties: It is a steel gray in color, hard, brittle and shiny metal. Some of the examples of steel alloys of manganese are P235GH steel, UNS S31600 and UNS S31254. The examples of ferromanganese alloys are Carbon ferromanganese, nitride ferromanganese and metallic ferromanganese. In steel making around 80% of manganese is needed.

The main components for ferro-manganese alloys are Iron (Fe) and Manganese (Mn). It even enhances the rolling and forging ability. Moreover in steel, manganese increases the hardness, toughness, and strength and wear-tear resistance. Manganese ore, atomic number and chemical symbol Now days different types of alloying agents are famous on the basis of Manganese which are copper manganese alloys, nickel manganese, ferro-manganese alloys and high manganese alloys. In the earth’s crust it is the 12th most existing element.Īlloying Behavior of Manganese: Manganese is a major alloying element. It also occurs in the ocean in the form of lumps called nodules. Manganese ores production is famous in China, Brazil, Australia and South Africa. It is always in combination with oxygen and other elements, Rhodochrosite Manganite, Psilomelane and pyrolusite are the common ores.

Occurrence: Manganese exists in nature, it is usually free but as a pure element it never occurs. Manganese belongs to the group 7B and period 4 of the periodic table. The pyrolusite and rhodochrosite are the most common minerals. Its minerals are extensively widespread, with manganese dioxide i.e. pyrolusite and manganese carbonate i.e. rhodochrosite. Manganese is the 5th most occurring metal in the Earth’s crust.
