    Multipurpose 4140 Alloy Steel Round Tubes

    Image of Product. Front orientation. Steel. Multipurpose 4140 Alloy Steel Round Tubes.
    Also known as chrome-moly steel, these alloy steel tubes resist fracturing from repeated stress. They’re used for a wide range of parts, including cylinders, rollers, and frames. For added wear resistance, they can be surface hardened with heat treating.
    Note: Tubes may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

    Thick-Wall Iron and Steel Unthreaded Pipe Nipples and Pipe

    Thick, Schedule 80 walls give this pipe better strength than our standard-wall steel unthreaded pipe. Weld it to fittings and additional lengths of pipe. Welded connections are stronger than threaded connections and less likely to leak. It is for use in noncorrosive environments.

    Weldable 4130 Alloy Steel Rectangular Tubes

    Image of Product. Front orientation. Steel. Weldable 4130 Alloy Steel Rectangular Tubes.
    Made from 4130 alloy steel, also known as chrome-moly steel, these tubes have low carbon content for good weldability. They’re often used for building frames and supports, since their flat sides make them easier to bolt than round tubes. To increase their wear resistance, you can harden them with heat treating.

    High-Pressure Iron and Steel Socket-Connect Pipe Fittings

    Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn’t need to align perfectly to the pipe. Slide pipe into the socket and weld for a strong, permanent connection. Fittings have heavy duty construction that stands up to high-pressure applications. They are for use in noncorrosive environments.
