Category Information
Balls - Metallic - Stainless Steel - 400 Grade400 Grade Stainless Steel Metallic Balls. Hardness: Rockwell C: 55-60. Includes 420 and 440C grades
- 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.
- AISI440C Stainless Steel.
