AISI 440C Steel Balls
AISI 440C Martensitic hardened stainless steel balls offers an advantage in terms of maximum integral hardness, together with a remarkable corrosion resistance to water, steam, oil, petrol and alcohol. Hardness features, high degree of surface finish and very precise size tolerances make this type of stainless steel perfect for the usage in Precision bearings, anti-friction bearings, special valves, conveyor belts and rollers, ballpoint pens. Also used in foodstuff, medical instruments, quick couplings, knotting devices, oil refinery devices, locking mechanisms, fasteners and quick-disconnect couplings Balls are available in AISI 440-C - W1.4125 - AFN Z100CD17 - DIN X 105CrMo17 - JIS SUS440C
