    Weldable 4130 Alloy Steel Rods

    Image of Product. Front orientation. Steel. Weldable 4130 Alloy Steel Rods.
    Made from 4130 alloy steel, also known as chrome-moly steel, these rods have low carbon content for good weldability. They’re often used to make gears and bushings. The surface of these rods is hardened to make them more resistant to wear and impacts. They’re also normalized, which is a heating process that relieves internal stress and helps prevent cracking during machining or additional hardening.
