Heat treatment of 45 gauge steel for gear sprockets
According to the requirements of the sprocket gear: if the impact is small case small can be surface carburizing, nitriding and other technologies! This way the surface hardness is higher, while the base hardness is lower, the wear resistance is good, and it is not easy to fracture. If the impact load is large, it should be tempered, that is, high-temperature tempering. 45#...
