    17-7PH Nut
    The nut is a fastener with internal threads and used in conjunction with a screw for mechanical parts for movement or power.

    BDF can offer all kinds of hot forged and cold formed nuts such as hexagon nuts, heavy hex nuts, hexagon coupling nuts, hexagon thin nuts, hexagon castle nuts, self locking nuts, hexagon domed cap nuts and other non-standard nuts according to customer drawings. The size ranges from M6-M100 in METRIC and 3/8” to 3-1/2” in INCH.
    After the solution treatment, it is unstable austenite structure, 17-7PH has good plastic toughness and processability, and has been adjusted to make the austenite precipitation carbide component change, and then through the martensitic transformation treatment, most of the organization into toughness Better low-carbon tempered martensite, this state for the use of steel state, have a good medium temperature mechanical properties. Corrosion resistance is better than general martensitic stainless steel.
    Applications:
    Aerospace industry, biomedical hand tools, chemical and food processing equipment, nuclear waste processing and storage, general metalworking, and paper mill equipment.
