Balls in these materials are case-hardened only (surface heat treatment ).
Low carbon steel balls offer considerable savings in all those applications which do not require the use of through hardened balls.
The most common applications include furniture wheels, beatings for drawers, locks, grease nipple, sliding boocks, toys.
