More Details About The Product


During the production of steel, Ferro Phosphorus is generated as a by-product. It skims from the top of the slag in the conversion process of pig iron. The basic Bessemer process, also called the Thomas process was one of the first processes to carry out this conversion. It is possible to make metal more brittle if required, by keeping different amounts of Ferro Phosphorus in the process.

Ferro Phosphorus is a Ferro alloy composed of iron and phosphorus in which the phosphorus content defines the quality of the product, ranging between 23% and 32%.

Ferro Phosphorus is gained as a by-product of steel manufacturing, the result of the conversion of pig iron, removing it from the side in contact with the slag produced during this process. It can also be obtained as a by-product in the production of phosphorus.

The use of ferro phosphorous is not a recent thing. On the contrary, it has been used as an alloying element in powder metallurgy since 1939. Sintered steel is alloyed with Ferro Phosphorus, instead of unalloyed sintered steel to improve strength. According to recent developments in Ferro Phosphorus powder, Sintered steels can have good ductility and high strength.

A new alloy with most desirable properties can be formed by adding Ferro Phosphorous to steel alloys. When Ferro Phosphorous is added to an alloy, it prevents oxidation as well as rusting of metals.


This iron and phosphorous combination has several applications, for instance it can be used:

  • The manufacturing of phosphorous castings
  • The manufacturing of High-Strength special Steels Low-Alloy (HSLA)
  • Its ability to be used as a deoxidizing agent in steels
  • As a manufacturing drying agent.
  • As an ingredient in high-strength low-alloy steel
  • As a dehydrating agent for removing water at the time duration of the alloy formation
