302SS (Stainless Steel Balls)

AISI type 302 stainless steel balls meet requirements for an unhardened ball with excellent toughness and resistance to corrosion. Corrosion resistance may be increased through annealing. Both non-annealed and annealed balls are widely used in valves and related equipment.

Stainless steel type 302 balls are capable of resisting corrosion by such agents as oxidizing solutions, most organic chemicals, food stuffs and sterilizing solutions. They are moderately resistant to sulfuric acids.

Applications include aerosol, sprayers, finger pumps mechanisms, milk machine blenders, food processing equipment and medical applications.
