Low Carbon Steel Ball.
Material：AISI1010/1015
Size Range：0.8mm-50.8mm
Grade：G100-G1000
Hardness：HRC:55-65
Features：have magnetic ,Carbon Steel Balls has superficial layer (case hardening), while the internal part of the ball remains soft metallographic tructure is ferrite , package often with oil . Usually electroplating when it is out of surface , it can be plated with zinc , gold , nickel , chrome and so on . have strong anti-wear functional .Comparison : the wear-resisting and hardness is not good than bearing steel ball ( The HRC of GCr15 steel ball is 60- 66 ) : so , the life is shorter relatively .
Application：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, craftwork, shelf, versatile ball,bags,small hardware,it can also be used for rubbing other medium.Castors, Dressers’ Bearings, Locks, Oilers And Grease Cups, Skates.drawers Slides And Window Rolling Bearings, Toys, Belt And Roller Conveyors, Tumble Finishing.
　

HighCarbon Steel Ball
Material： Size Range：2mm-25.4mm
Grade：G100-G1000
Hardness：HRC:50-60
Features ：
AISI1070/1080 Carbon Steel Balls, & High carbon steel balls has remarkable advantage in terms of whole hardness index, which is about 60/62 HRC and grants a higher wear and load resistance compared to common low carbon hardened steel balls.
(1)Core-hardened
(2)Low resistance to corrosive attack
(3)Higher Load and longer life than low carbon steel ball
Application：Bike’s accessories, furniture ball bearings, sliding guides, conveyor belts, heavy load wheels, ball support units. Low precision bearings, bicycle & automotive components, agitators, skates, polishing and milling machines,Low precision bearings.
