DESCRIPTION
Manganese is intentionally present in most grades of steel and is a residual constituent of virtually all others. Aside from its historic importance as a desulfurizer and deoxidizer, manganese is undoubtedly the most prevalent alloying agent in steels, after carbon. Understandably, therefore, ferromanganese is the most widely used ferroalloy.
Of the 15 steelmaking manganese products recognized in ASTM standards, the most important is high carbon (standard) ferromanganese. It is generally sold in two manganese concentrations: 74-76% and 78-82%, with the latter predominating. Carbon content will not exceed 7.5%, silicon will be less than 1.5% and sulfur and phosphorus, 0.03 and 0.3 %, respectively. A low phosphorus variety is available as well.
