    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.

    Hardened Multipurpose 4140 Alloy Steel Rods

    These rods and discs keep their strength in temperatures up to 800° F. They're hardened for increased abrasion and impact resistance. Plus, they’re stress relieved, so there’s less chance of warping during machining. Also known as chrome-moly steel, 4140 alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress.
    Note: Rods may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.
