    Highly Corrosion-Resistant 316 Stainless Steel Balls

    Image of Product. Front orientation. Stainless Steel. 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.
