Effect of tempering on the properties and microstructure of 00Cr13Ni5Mo

摘要

In this study,normalized 00 Cr13 Ni5 Mo low-carbon martensitic stainless steel was tempered at temperatures ranging between 500-700 ℃ for 8 h and its mechanical properties were determined. The results show that the mechanical properties vary with a variation in the tempering temperature. Samples tempered at 650 ℃exhibited a good combination of properties and a low yield ratio. Scanning electron microscopy observations and Xray diffraction analysis revealed that the tempering process involved carbide precipitation,austenitic inversion,and quenching,and the properties of materials changed with a change in the tempering temperature.
