    About Steel
    industrial info icon

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

    Impact-Resistant Ultra-Machinable Ductile Iron Rods

    With a high amount of ferrite, these cast iron rods are easier to machine without cracking than other impact-resistant ductile cast iron rods. Use them to create bushings, gears, pulleys, and pistons. These rods are also known as 65-45-12 ductile iron rods. All conduct electricity. They will become magnetic if exposed to a magnetic field. They’re often used to replace low and medium carbon steel rods.

    Impact-Resistant Ultra-Machinable Ductile Iron Bars

    Image of Product. Front orientation. Steel. Impact-Resistant Ultra-Machinable Ductile Iron Bars.
    Ductile cast iron is strong, resilient, and able to handle repeated stress without breaking. It also absorbs vibration, so finished parts run quieter than those made of steel.

    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.
