Influence of Hardness Variation and Defects on Fatigue

The hardness of quenched and tempered SUJ2 is homogenous,in contrast to that of carburized SCM820PRH (SCM) which decreases from surface to core.These steels are investigated in terms of their monotonic tensile properties and fatigue behavior.A number of predictive methods were used to describe the fatigue behavior of these steels.Influence of Hardness Variation and Defects on Fatigue The hardness of quenched and tempered SUJ2 is homogenous,in contrast to that of carburized SCM820PRH (SCM) which decreases from surface to core.These steels are investigated in terms of their monotonic tensile properties and fatigue behavior.A number of predictive methods were used to describe the fatigue behavior of these steels.How to Heat Treat 52100 - Knife Steel NerdsMay 13,2019 suj2 hardness before tempering#0183;The hardness in general was lower than the DET samples.Perhaps the shorter hold time (10 vs 15 minutes) contributed to the difference.Lower tempering temperature led to reduced toughness,as expected.Again the 300 suj2 hardness before tempering#176;F temper fits the same trend line as the rest of the samples,so the thermal cycling does not seem to have affected toughness.
