Feature:Phosphorus is a harmful impurity in most steels. But it has a special role in some cases. For example, the addition of phosphorus to some kinds of steel can improve the strength, corrosion resistance and machinability of steel, but increase the brittleness of steel. Adding phosphorus to cast iron can improve the fluidity of molten iron and thus improve the properties and surface quality of castings. Gray cast iron contains 0.5% phosphorus, which can increase its tensile strength. The wear-resistant cast iron contains about 0.15% phosphorus, which can significantly improve its wear resistance.
Phosphorus iron can be used as additive of phosphorus in steelmaking and casting. The company supply high quality refined phosphorus iron ball, phosphorus content of more than 23%, no impurities, no powder, phosphorus content is particularly stable, beautiful appearance, good strength, good operation before furnace batching, particle size can also be processed according to user requirements, transportation and loading and unloading basically no powder.
