Overview
Ferro Silico Manganese is used as a deoxidizer and an alloying element in steel. This can be used as a substitute for Ferro Silicon and Ferro Manganese when added to make different types of steel.
Both silicon and manganese have an important influence on the properties of steel, depending on the amount added and the combined effect with other alloying elements. Silicon and manganese have a strong affinity for oxygen, and will act as deoxidizers.
Deoxidation with SiMn results in cleaner steel, as the liquid manganese silicate formed coagulates and separates easier from the melt, compared to solid SiO2 formed during FeSi deoxidation. Use of Ferro Silico Manganese adds less phosphorus, carbon, and nitrogen to steel compared to standard FeSi 75 plus HC FeMn.

Ferro Manganese
Overview
Ferro Silico Manganese is used as a deoxidizer and an alloying element in steel. This can be used as a substitute for Ferro Silicon and Ferro Manganese when added to make different types of steel.
Both silicon and manganese have an important influence on the properties of steel, depending on the amount added and the combined effect with other alloying elements. Silicon and manganese have a strong affinity for oxygen, and will act as deoxidizers.
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.
