Martensitic stainless steel balls, they are characterized by remarkable
hardness, wear resistance, surface finishing, narrow dimensional tolerances. For
that reason this type of steel is frequently used in precision devices. Balls
are provided in the passivated state.
Applications of AISI440C Stainless Steel Balls
Precision bearings, anti-friction bearings, special valves, conveyor belts and rollers, ballpoint pens. They are used in foodstuff, medical instruments,quick couplings, recirculating ball bearings, knotting devices, oil refinery devices.
