What material is better for cast curved plate chain sprockets?

2026 04/10

Cast curved plate chain sprockets are a type of transmission component that works with chains, similar to how gears work with racks.

Commonly used materials for cast curved plate chain sprockets are generally 45# steel. Ordinary 45# steel sprockets can already meet the operating conditions of sprockets.

Of course, some people choose 40Mn (40 manganese steel) or 45Mn (45 manganese steel). There is a qualitative difference between manganese steel sprockets and 45# steel sprockets.

Naturally, the choice of material for cast curved plate chain sprockets also depends on the application requirements. If the rotational speed is low and the pulling force is small, you can choose the more cost-effective 45# sprocket material. Therefore, the material selection depends on the specific use of the sprocket.76dbe1149e3de793b9885c8476e192d5
