Through-hardened carbon steel balls are manufactured from high carbon steel and heat treated to achieve high hardness and wear resistance throughout the entire cross-section. They are widely used in industrial applications requiring higher load capacity and improved durability compared with low carbon steel balls.
Also known as high carbon steel balls, AISI 1085 / 1086 steel balls provide higher hardness and wear resistance than low carbon steel balls.
AISI 1085 / 1086 carbon steel balls are manufactured from high carbon steel and heat treated through the entire cross-section to obtain consistent hardness and improved mechanical strength.
Compared with case-hardened low carbon steel balls, through-hardened carbon steel balls provide better wear resistance and higher load capacity for demanding industrial applications.
