Basic situation of automobile gear steel abroad

In foreign countries, the carburized gear steel initially used is basically manganese steel and manganese chromium steel. For example, the Japanese mainly use smn420 and SMN C420, while the Germans mainly use 16MnCr5 and 20mncr5. This kind of steel is cheap and has good comprehensive properties. At that time,...
