AISI 1010/1015 Carbon Steel Balls
Applied Area: 1010/1015 carbon steel ball is an ordinary steel ball, it has low price, high precision and wide use. It is used in bicycle, bearings, chain wheel, craftworks, shelf, versatile ball, bags, small hardware. It can also be used for rubbing other medium.
Speciality: It is magnetic, it must be plated when it is out of surface, it can be plated with zinc, glod, nickle, chrome and so on. The frictional resistance is strong, the HRC is 50-55.
Comparison: The frictional resistance and hardness is worse than bearing steel ball (the HRC of GCR15 steel ball is 60-66), so the working life is shorter.
440C Stainless Steel Balls
Applied Area: 440C stainless steel ball is used in the industries of high precision and antirust: avigation, bearings, valve, petroleum facilities and so on.
Capability: It is very hard to produce 440C stainless steel ball, the heat treatment is complicated, it is easy to split, the precision must be high, it is the most rigid, HRC≧58. Its hardness is close to bearing steel ball, but it is more antirust and anticorrosive than the bearing steel ball.
Comparison: 440C stainless steel ball is more antirust and anticorrosive than 440 stainless steel ball. The frictional resistance is enhancing while the hardness is increasing.
