Balls - Metallic - Stainless Steel - 304 Grade

23 Products in this selection
  • Grades shown are AFBMA and ISO3290-1 which relates primarily to the ovality of the ball rather than the diametrical tolerance
  • General balls offered for sale may be from different ball lots, so the diametrical tolerance shown, indicates a variance that might be encountered if balls of different gauges are mixed, unless a ball gauge is specified for the part.
  • For diametrically critical applications, a special quote can be obtained for balls of a specified ball gauge.
  • A2 Grade. Low magnetic permeability. Good corrosion resistance. Excellent for use in handling foodstuffs.
  • Non annealed. Hardness: Rockwell C: 25-39. Specific Gravity: 7.916.
  • Low magnetic permeability. Good corrosion resistance. Excellent for use in handling foodstuffs.
  • Note! Increase in magnetic permeability may occur due to the grinding process and can be relieved by heating to over 1000 oC.
