316L (Stainless Steel Balls)

316 Stainless Steel Balls

AISI type 316L 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.

Type 316L is a low carbon austenitic, chromium-nickel-molybdenum stainless steel with general corrosion resistance similar to type 316, but with superior resistance to intergranular corrosion following welding or stress relieving.

It is suggested for use in certain corrosive environments for parts that are fabricated by welding and cannot be subsequently annealed. Parts made from 316L are generally limited to service temperatures up to 800ºF (425ºC).
