5CrNiMoV Mould Steel Bar

 

5CrNiMoV die steel is a hot forging die steel with high wear resistance produced by electric arc furnace refining and vacuum technology. 5CrNiMoV die steel has high purity, good toughness, high strength, and good wear resistance. 5CrNiMoV hot work die steel is general Used to make various large and medium forging dies.

 

Although 5CrNiMoV steel has been widely used in industrial applications, the hot deformation process of the steel has been less investigated and only little information on the dynamic recrystallization (DRX) behavior or flow stress behavior of the steel has been reported. So far, the influence of annealing, forging state, and quenching tempering state on the microstructures of steel matrix composites (SMCs) with 5CrNiMo steel as matrix was investigated by the metallographic analysis method. The changes in strength, hardness, and impact ductility of 5CrNiMo steel after the addition of different contents of RE La element were investigated. 

 

Besides, activation energies for plastic deformation of the low alloy steel Din 56CrNiMoV7 (5CrNiMoV) were studied using tensile tests in the temperature range 660–800°C [20]. To supplement the research on the forming property of hot work die steel 5CrNiMoV, the present study explored the DRX behavior and microstructure evolution at different deformation conditions based on the isothermal hot compression tests. And a constitutive equation, a DRX model, and a DRX grain size model were constructed to predict the DRX evolution.
