Material: High quality carbon steel (such as 45 # steel) is the mainstream material for manufacturing sprockets, and after quenching and tempering treatment, its hardness can reach HRC28-32. Stainless steel sprockets are suitable for anti-corrosion scenarios such as food machinery, while powder metallurgy processes are suitable for mass production of small sprockets.
Manufacturing process: The manufacturing process of sprockets includes steps such as mixing, forming, sintering, and post-treatment. Forming is usually completed by a mixer, while sintering is carried out in a vacuum state to obtain high density and excellent product quality. Post treatment includes sandblasting, oxidation, and other operations to improve the surface quality and wear resistance of the sprocket.
