420 stainless steel balls are primarily used in Special bearings, anti-friction bearings, special pumps, recirculating balls, lighters, automotive seat-belts and components.
420 stainless steel balls. This type of stainless steels has good resistance against corrosion together with the high hardness. The balls made of this material are suitable for valves, special bearing etc., in which the protection against rustproof-grease is poor or absent. Their resistance against corrosion caused by water, steam, air, is good. This kind of steel is not suitable to be used with chemical agents.
