The effect of phosphorus in the form of Fe3P (up to 3%) on the sintering behavior and mechanical properties of sintered ferritic stainless steel (434L) was investigated. The Fe3P and 434L powder mixtures were cold compacted using single action uniaxial pressing under 600 MPa pressure and sintered in the solid state and super solidus liquid state at 1100 and 1300 °C, respectively, under a (95% N2 and 5% H2) atmosphere. The density, hardness, yield strength, ultimate tensile strength and tensile rupture strength improved by 5%, 18%, 24%, 19% and 27%, respectively, and the rate of corrosion reduced by 1.64 times for 434L mixed with 3% Fe3P.
