    Steel Balls

    Image of Product. Front orientation. Steel. Steel Balls.
    Multipurpose Low-Carbon Steel—Low-carbon steel balls are our easiest steel balls to machine. They are often used for parts that don’t require high strength, such as knobs. These balls can be surface hardened with heat treating for added wear resistance.
    Wear-Resistant 52100 Alloy Steel—High carbon and chromium content makes this 52100 alloy steel extremely hard and resistant to wear. It’s also known as chrome steel. Often used as bearings, these balls are hardened for increased abrasion and impact resistance.

    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 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.

    Extra-Hard C2 Tungsten Carbide

    Machine long-lasting tools, such as end mills and inserts, with these rods. Tungsten carbide, sometimes called carbide, is harder than our Corrosion-Resistant Tungsten with excellent wear resistance. Its extreme hardness lets cutting edges stay sharp far longer than high-speed steel.

    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.

    High-Strength Fracture- and Wear-Resistant Zirconia Ceramic Balls

    Image of Product. Front orientation. Ceramic. High-Strength Fracture- and Wear-Resistant Zirconia Ceramic Balls.
    Often used instead of metal in bearings and rollers, these balls are ideal for applications where strength under heavy loads and wear resistance is needed. It's the addition of yttria that gives this zirconia more strength and lowers the chances of cracking from impact than standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, extending the life and reliability of the material. It also means this zirconia blend resists wearing down from rubbing against another part or abrasion from chemical slurries.
    These balls do not withstand rapid temperature changes or high temperatures as well as other high-performance ceramics such as ceramic alumina and silicon nitride ceramic.
