Carbon steel balls are classified into low-carbon steel balls (0.04% to 0.25%), and high-carbon steel balls (0.6% to 1.35%) depending on the content of carbon. The carbon content also changes the properties of the carbon spheres. As the carbon content increases, both the strength and hardness of the steel will increase, but their toughness and weldability will decrease.

Low Carbon Steel Balls

Low carbon steel balls are usually used in applications where moderate loads and low speed are requested for example Castors, Conveyors and non-precision bearings. There is a significant price saving compared to High Carbon Chrome balls

The main feature of this type of ball is the carburised case with a soft core giving resistance to shock loads, good load carrying ability and excellent resistance to surface wear.

High Carbon Steel Balls 

High Carbon Steel Balls is hardened by carburization and quenching , It can be used for higher load
