304 Grade Stainless Steel Metallic Balls. A2 Grade. Low magnetic permeability. Good corrosion resistance. Excellent for use in handling foodstuffs.

• 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.
• 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.
