    Compare over 50 grades of steel and cast iron to find the right material for you—all with material certificates for traceability.

    Tight-Tolerance Low-Carbon Steel Rods

    Image of Product. Front orientation. Steel. Tight-Tolerance Low-Carbon Steel Rods.
    These rods are precision ground and held to a strict straightness tolerance, so they're ready for turning in a lathe. 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. For added wear resistance, this material can be surface hardened with heat treating.
