    industrial info icon

    Compare over 25 types of stainless steel to find the right material for you—all with material certificates for traceability.

    Hardened Ultra-Wear-Resistant 440C Stainless Steel Balls

    Image of Product. Front orientation. Stainless Steel. Hardened Ultra-Wear-Resistant 440C Stainless Steel Balls.
    The best choice for high-performance bearings and valves, these 440C stainless steel balls are among the strongest, hardest, and most wear-resistant we offer. 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—even at temperatures up to 800° F. They’re made to strict ISO 3290 standards for roundness and surface quality.
    These balls are magnetic, so you can use them in separators, sensors, and automated handling systems that use magnetic pickup or positioning.
    Grade 100—Great for mechanical applications where you don’t need the exacting tolerances of Grade 25.
    Grade 25—Precision-ground to tighter tolerances than Grade 100 balls. Use them in high-accuracy assemblies.

    Multipurpose 304 Stainless Steel Balls

    Image of Product. Front orientation. Stainless Steel. Multipurpose 304 Stainless Steel Balls.
    Whether inside pumps or furnace parts, these balls can be used in any mildly corrosive, high-temperature conditions. Made of 304 stainless steel, they won’t degrade when exposed to mild chemicals and water, even at temperatures up to 1500° F. 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. These balls are made to strict ISO 3290 standards for roundness and surface quality.
    Although 304 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.

    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.
