Effect of Heat Treatments on the Mechanical and

In 38CrSi, the corrosion rate decreases as compared to the as received sample from 0.515 to 0.486 mpy in quenching and tempering heat treatment, while in AISI 4140 steel the corrosion rate 30CrMo Steel Equivalent, Chemical Composition, Mechanical 30CrMo Steel. 30CrMo steel is a Chinese alloy steel for engineering and machine structural use, has high strength and high toughness, and has good high temperature strength at temperatures below 500 °C. 30CrMo material also has good machinability, medium cold bending and plasticity, high hardenability, good weldability, and is generally used in the adjusted state.Effect of Heat Treatments on the Mechanical and Jul 10, 2019· The aim of this investigation was to compare the microstructural, mechanical and electrochemical corrosion characteristics of 38CrSi steel with widely used AISI 4140 steel under various heat treatment processes to widen its field of applications. Experimental steels 38CrSi and AISI 4140 were subjected to austenitizing at 900 °C for 30 min followed by annealing, quenching in oil and
