Usage

Description

Ferrophosphorus is a solid alloy of iron and phosphorus, typically containing either 18% or 25% phosphorus, used in the steel industry for adjusting the phosphorus content of special steels.

Uses

Used in Steel Industry:
Ferrophosphorus is used as an additive for adding phosphorus to steels, which enhances their free-cutting properties and prevents sticking during annealing processes.
Used in Open-Hearth Steels:
Ferrophosphorus is used as a phosphorus source in open-hearth steels to improve their machinability and reduce the risk of sticking during the annealing process.
Used in Tinplate Steels:
Ferrophosphorus is used in tinplate steels to prevent thin sheets from sticking together when rolled and annealed in bundles.
Used in Pig Iron Production:
Ferrophosphorus is made by melting phosphate rock together with the ore in the process of making pig iron, contributing to the overall phosphorus content in the final product.
Used in Stainless Steels:
Ferrophosphorus, along with other master alloys like ferroselenium, is used in stainless steels to provide free-machining qualities and improve the overall performance of the material.

Reactivity Profile

Ferrophosphorus, a less reactive metal alloy, is a reducing agent. Can react exothermically with oxidizing acids to form noxious gases. May catalyze polymerization and other reactions, particularly when finely divided. May react with halogenated hydrocarbons, sometimes forming explosive compounds Less reactive in bulk form (sheet, rod, or drop) than when finely divided. May form irritating vapors and toxic gases, such as phosphorus oxides or phosphoric acid when involved in fire.

Fire Hazard

Special Hazards of Combustion Products: Irritating vapors and toxic gases, such as phosphorus oxides or phosporic acid, may be formed when involved in fire.
