Ferro Silicon Manganese.

level is most important in determining the price differential between the various ferrochrome grades. Low carbon ferrochrome is now added mostly for final chemistry adjustments in the production of stainless steel. Nitrogen-bearing low carbon ferrochrome provides a simple means of making a nitrogen addition to chromium bearing steels, particularly conventionally melted stainless grades. These grades of stainless can also be produced economically with elemental N2 in the AOD.
