Stainless Steel AISI 302/304

Description

These Stainless Steel balls go through two processes - annealing (where they're heated quickly and allowed to cool slowly) and passivation (where a light coating of metal oxide is applied) - both of which help them resist corrosion more effectively.

Benefits

Because they're resistant to corrosion, these balls are highly suitable for use in the food industry or where oxidising solutions and organic chemicals are present. This, blended with material toughness makes them many companies' firstĀ  choice for use in a wide range of demanding environments. Note: these balls are not resistant to sulphuric acid.

Use

You'll find them widely used in valves, aerosols and finger pumps (spray, dispenser and trigger sprays) as well as household items like coffee makers and grinders.
