Medium
Carbon Ferro Manganese(MedC FeMn)
Application :
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.
Manganese addition agents are generally chosen on
the basis of carbon content. Inexpensive standard
ferromanganese is used when the steel is well
oxidized (low in carbon) or when higher residual
carbon contents are allowable. As maximum steel
carbons become more restricted it is necessary to
switch to the more costly low-or medium carbon
ferroalloys. The final aim chemistry will determine
which addition agents can or cannot be used. Silicon
content is often a second deciding factor.
