316 Stainless Steel Miniature Balls

AISI 316 stainless steel balls meet requirements for an unhardened ball. 316 is an austenitic, Chromium-Nickel-Molybdenum stainless offering superior corrosion resistance due to the higher Nickel, Molybdenum content. Typical applications include fishing equipment, textile finishing equipment and valves.

Passivation is available upon request.
