Performance and application characteristics for 20CrNi2Mo steel , analysis demonstrated a the carburized surface enhancement of 20CrNi2Mo steel used as a heavy duty gear material instead of 20Cr2Ni4 steel feasibility study the overall strengthening the 20CrNi2Mo steel heat treatment process , organization and performance . Heat treatment deformation law overloaded gear using one-way ANOVA statistical analysis , the results showed that the tendency large 20Cr2Ni4 steel heat treatment distortion . Through experimental comparison steel of 20CrNi2Mo enhanced process performance and 20Cr2Ni4 steel carburized surface and microstructure , mechanical properties and wear performance , process performance of 20CrNi2Mo steel better than 20Cr2Ni4 steel surface with good performance with the core part , to good use effect. Experimental study 20CrNi2Mo steel quenching overall strengthening heat treatment process on the microstructure , hardness , ductility, toughness and wear resistance , the results show , 20CrNi2Mo by steel Toughening Process overall strengthening , performance differences . Through the research , analysis , 20CrNi2Mo steel as carburizing steel used in heavy duty gear and other artifacts can simplify the heat treatment process , reduce the heat treatment distortion the situation improve workpiece purpose ; as a low-carbon martensitic steel , can be applied to bucket teeth and other requirements of a wear-resistant , impact-resistant parts , by improving its heat treatment process can make it wear resistance , impact resistance and other performance improvement .
