FeP24 Ferro Phosphorus 24% Lump / Grain / Powder For Casting Additives
Phosphorus iron honeycomb appearance, phosphorus is 20-26%, 0.1 6% of intergrowth compounds containing silicon. Phosphorus in the steel industry as an alloying agent, iron alloy additives for use in the metallurgical and deoxidizer.
In general steel products, phosphorus is harmful ingredients, but in some special products, the addition of phosphorus, can improve the performance of certain aspects of steel. Phosphorus iron is widely used in roll, auto cylinder liner, engine roller and large castings in order to increase mechanical parts corrosion resistance and abrasion resistance.
As an alloy agent, it can also produce phosphate in steel making, it can improve the corrosion resistance and machinability.
Product Function
1.Mainly used for alloy agent and deoxidizer in the metallurgical industry special steel.
2.Widely used in rolls, automotive cylinder liners, engine tollers and large castings to increase the cossion resistance and wear resistance of mechanical components.3.Phosphorus is partially soluble in ferrite in steel, can reduces the ductility and toughness of steel and increase the brittle transition.
3.Phosphorus is partially soluble in ferrite in steel, can reduces the ductility and toughness of steel and increase the brittle transition.
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.
