Ferro Phosphorus, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resulting alloy. Adding Ferro Phosphorus to an alloy prevents oxidation and the later rusting of metals. Ferro Phosphorus exists in many allotropic forms. Ferro Phosphorus, a combination of phosphorus with iron, is used as an ingredient in high-strength low-alloy steel and is used as a good dehydrating agent that can remove water during the alloy formation. Ferro Phosphorus is a by-product of the steel manufacturing process, as when pig iron is being converted, the conversion process will skim Ferro Phosphorus from the top of the slag. This was first done using the basic Bessemer process or the Thomas process.
