In this work, the effect of pressing technique on the microstructures and tensile behaviors of powder metallurgy (PM) steel with different composition were investigated. Weighed powders for the desired chemical composition were mixed in an industrial conic mixer for 1 h and then cold and warm pressed at 700 MPa with a die. The pressed PM steels were sintered at 1400 degrees C. PM steels with different pressing technique were analyzed in terms of micrstructure and tensile test. Results indicated that PM steels with warm pressing technique showed the highest values in yield strength (YS) and ultimate tensile strength (UTS).
