ferro phosphorus

Ferro phosphorus improves machinability and strength in low carbon steel. By adding 0.011 to 0.085% by weight of phosphorus to low carbon ferritic steels, the increase in phosphorus content causes the grain size to decrease, the yield strength to increase and the final tensile strength to increase, the intragranular and intergranular hardness increases and limited changes in the amount The increase in length is relative.
Application: production of all kinds of steel to improve mechanical properties
