Phosphorus additions can be used to strengthen sintered iron. But at contents above 0.6% P, the alloy becomes brittle.

Sulfur and phosphorus contents of coal Sulfur adversely affects the mechanical properties of steel and is the cause of red-shortness, that is, brittleness in the heated state, while phosphorus increases the tendency of a metal to become cold-short, that is, brittle at reduced temperatures.
