Introduction to standards:
This standard specifies the metallographic grade of heavy-duty gears after spheroidizing annealing or high-temperature tempering after completing the carburizing heat treatment process. This standard is applicable to heavy-duty carburized gears made of steel such as 20CrMnTi, 20CrMnMo, 20CrNi3Mo, 15CrNi3Mo, 10Cr12Bu4, etc.; and is applicable to spheroidizing annealing or high-temperature tempering metallographic structure inspection of parts with a carbon content of 0.75~1.05%C in the carburized layer. .
