Silicomanganese SiMn17

Ferrosilicomanganese is a brittle alloy of iron, silicon and manganese, used in metallurgy as a steel deoxidizer. Gives the alloy impact resistance and bending brittleness. The surface of ferrosilicomanganese pieces should be free of foreign materials. Traces of non-stick materials (lime, sand), slag film, and single slag inclusions are allowed. The mass of inclusions should not exceed 0.5% of the batch mass.

SiMn17(A) 15.0 - 20.0 65.0 2.5 0.10 0.02
SiMn17(B) 15.0 - 20.0 65.0 2.5 0.60 0.02

At the consumer's request, class B ferrosilicomanganese is produced with a mass fraction of phosphorus every 0.05%, in grades SiMn12, SiMn17, SiMn22 up to 0.10%, and in grade SiMn25 up to 0.05%.

The designation of the ferrosilicomanganese grade includes the alloy base, mass fraction of phosphorus and size class.
