    Multipurpose Low-Carbon Steel Rods

    Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into low-strength fasteners, pins, and axles. You can surface harden this material for added wear resistance.
    If you don't see the size you're looking for, check out our Made-to-Order Low-Carbon Steel Rods.

    Cold Worked—Cold-worked products have a finished look and quality. The cold-working process gives the steel consistent strength, hardness, and dimensions throughout.
    Hot Rolled—Hot-rolled products are great for forming and fabricating. The steel undergoes less stress in the finishing process and has a little more give, so you can more easily bend and form it. It does however have a rougher surface finish than cold-worked steel.

    Extra-High-Strength Ductile Iron Rods

    Image of Product. Front orientation. Steel. Extra-High-Strength Ductile Iron Rods.
    Containing more pearlite and less ferrite, these cast iron rods are stronger and harder than standard ductile cast iron. They are resilient and able to withstand repeated stress without breaking. These rods also absorb vibration, so their finished parts run quieter than those made from steel. Use them to create bushings, gears, and pistons. To increase their wear resistance, you can harden these rods through heat treating.

    Image of Product. Front orientation. Steel. Highly Fatigue-Resistant 4340 Alloy Steel Rods.
    Made of 4340 alloy steel, these rods hold up to high heat, hard impacts, and heavy wear thanks to high levels of nickel, chromium, and molybdenum. They’re commonly used for high‑stress components such as shafts, gears, and other load‑bearing parts. For even more wear resistance, you can harden the surface with heat treating.

    Made-to-Order A2 Tool Steel Rods

    Image of Product. Front orientation. Steel. Made-to-Order A2 Tool Steel Rods.
    When an off-the-shelf size won't do, we'll get you the exact dimensions you need.
    Made of A2 steel, they are more wear resistant than O1 rods and discs. They also keep a sharper cutting edge. When heat treated for added wear resistance, they don’t require baths or quenching and can be air-hardened. A2 tool steel is widely used for punches, blades, and hammers. These rods are decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them more machinable and leads to better results from heat treating or finishing. With an oversized diameter, these rods and discs let you finish to your exact requirements.
