302 Stainless Steel Miniature Balls

AISI 302 stainless steel balls offer excellent corrosion resistance in organic, industrial and marine environments. Non-magnetic properties are combined with exceptional toughness at all temperatures, making these balls excellent selections for many applications including aerosol sprayers, finger pump mechanisms and food processing equipment.

Passivation is available upon request.
