    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.

    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.

    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.

    Tumbling Media for Steel, Stainless Steel, and Hard Metals

    Ball

    Made of a hard material, this tumbling media is tough enough to finish steel, stainless steel, and other hard metal parts. Choose the shape that best matches the contours of your part and a size that’s large enough not to get stuck in recesses and holes. You can also mix shapes and sizes to tailor the finish to your part.
    For Mirror Finish—Use this media as the final step in your finishing process to create a reflective finish. Ideal for fragile parts, it rubs the surface without removing material.
    Ball—Best for gentle finishing. Balls are less aggressive than other shapes, so they smooth your workpiece without flattening any details.
    Wet Tumbling Condition—Use this media with liquid cleaners.
