The size of the sprocket determines the structure of the sprocket
The sprocket material should ensure that the sprocket has sufficient contact strength and wear resistance, so the tooth surface is heat-treated. Low speed, light load, smooth transmission, medium carbon steel; medium carbon steel adopts medium speed and medium load quenching, and the hardness is higher than HRC40~45. High-speed, heavy-duty, continuous working transmission, low-carbon steel appearance carburizing and quenching (such as 15, 20Cr, 12CrNi3 steel quenching to HRC55~60). Or quench the surface of medium carbon steel (such as 45, 400Cr, 50Mn2, 35CrMnSi, 45crni, etc.) to HRC45~55.
