Carbon steel balls could be separated into soft carbon steel balls and hard carbon steel balls according to their surface. Surfaces of hard carbon steel balls are strengthened by carburization and quenching while surfaces of soft carbon steel balls are not. These balls are used in bicycles, locks, shelf, bags etc. Our company supplies both soft and hard carbon steel balls.
