  • Manganese Wikipedia

    Manganese is a chemical element with the symbol Mn and atomic number 25. It is not found as a free element in nature [not verified in body]; it is often found in minerals in combination with iron.Manganese is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels.. Historically, manganese is named for pyrolusite and other black minerals from the

  • The Properties and Effects of Manganese as an Alloying

    Silicomanganese alloy contains 65 to 68% manganese, 16 to 21% silicon, and 1.5 to 2% carbon, and is generated by the smelting of slag from manganese ore or high-carbon ferromanganese with a quartz flux and coke. The alloy’s carbon content is reduced due to the presence of silicon. A silicomanganese with relatively lower carbon content can be achieved by resmelting silicomanganese with more
