As with all precision balls, stainless steel balls are defined by their nominal diameter, the raw material from which they are made, and their degree of precision.
Stainless steel balls are primarily used in humid or corrosive environments.
Factors such as special hardness requirements or specific resistance to salt spray can also help guide the choice between different types of stainless steel.
There are numerous standardized diameters, both in metric and inch sizes.
