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.
