Influence of Quenching and Partitioning Temperature on Mechanical Properties of Steel 37MnSi5

详细

The influence of the temperature of heating for quenching and subsequent heating for redistribution of carbon between martensite and retained austenite (partitioning) on the mechanical properties of steel 37MnSi5 (35GS) is studied. The tested quenching temperatures are 210, 238 and 270°C and the partitioning temperatures are 300, 400 and 450°C. An optimum combination of strength and ductility exceeding the level of the properties of the steel after standard quenching and tempering or austempering is obtained.
