Stainless Steel Balls (316)

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

When it comes to the process of manufacturing a 316 stainless steel ball to the highest quality available, New England Miniature Ball has the experience to meet your most exacting requirements! Whatever the grade or tolerance is, we can create a 316 stainless steel ball to your exact specifications. Fill out the Contact form above to learn more about our capabilities!

Passivation is available upon request.
