For many problems and defects in 20Cr2Ni4 steel application, through the analysis of mining machinery gear working condition, comparative study in cutting, forging, carburizing layer performance, heat treatment process, heat treatment deformation, mechanical properties, deformation resistance and abrasion resistance of overload capacity of 20CrNi2Mo and 20Cr2Ni4 steel respectively. The results show that, using 20CrNi2Mo steel instead of 20Cr2Ni4 steel in the mining machinery heavy-duty gear is feasible.
