Hollow 440A Stainless Steel Balls
 |
These lightweight balls are often used in floats, valves, and other parts to regulate liquid level and flow. Made of 440A stainless steel, they resist impact and corrosion in temperatures up to 250° F. Their polished surface prevents contaminants from sticking to them.

Highly Corrosion-Resistant 316 Stainless Steel Balls
|
Trusted in marine and chemical-processing valves, these balls stand up to some of the most highly corrosive environments. Made of 316 stainless steel, they hold up to sulfuric acid, chlorine, and other harsh chemicals in temperatures as high as 1500° F. They’re a step up from balls made of 304, which have similar strength and temperature performance. They’re passivated to wash away surface particles that cause rust, and they’re polished to a mirror-like finish that contaminants can’t stick to. The result is balls that stay smooth and stand the test of time. They’re made to strict ISO 3290 standards for roundness and surface quality.
Although 316 balls aren’t as wear resistant as 440C balls, they’re easier to fabricate. They’re also nonmagnetic.
Grade 100—Great for mechanical applications where you don’t need the exacting tolerances of Grade 25.
