    Thread MP35N Bolts Fastener Full Strength With Stress Corrosion Cracking Resistance

    MP35N Thread Bolt Fastener UNS R30035 AMS 5844 260 to 300 ksi (1793-2086 MPa)

    MP35N alloy is work-strengthened and aged to obtain strength levels of 260 to 300 ksi (1793-2086 MPa) in its full strength and stress corrosion cracking resistance (SCC) for harsh environments. MP35N® alloy resists corrosion in hydrogen sulfide, salt water and other chloride solutions, as well as the mineral acids (nitric, hydrochloric, sulphuric). In addition, it has exceptional resistance to crevice cracking in seawater and other hostile environments.


    Since its development, MP35N has been successfully used in applications outside of the aerospace industry. For instance, it is the highest strength material approved for structural components in aggressive, sour well environments (NACE specification MR0175 Sulfide Stress Cracking Resistant Metallic Materials for Oil Equipment).

    MP35N is often selected as a fastener alloy for its ability to resist stress corrosion cracking. In laboratory tests, MP35N alloy samples were loaded to 90% of their proportional limit and alternately immersion tested in 3% salt solution for 10 minutes and in moving air for 50 minutes. After 2500 hours, no evidence of general corrosion or cracking appeared.

    Crevice corrosion tests were performed on MP35N, MP159, 13-8Mo and Custom 455 alloy bolts in a 10% ferric chloride solution. Several bands of electroplater’s tape were applied to the bolts to promote the conditions necessary for crevice corrosion. Following 6 hours of exposure to the solution, Multiphase alloy bolts exhibited no visible evidence of corrosion while the other alloy bolts experienced extensive attack.

    The properties of mp35n are realized by work hardening, martensitic transformation and aging treatment. Through cold working, a part of the matrix is transformed into solid phase transition from FCC crystal structure to HCP structure. This transformation is due to the high content of cobalt in the alloy and is called "multiphase reaction". There are two kinds of different crystal structures, the movement of the dislocation constitutes obstacles and leads to obvious strengthening. The subsequent age hardening stabilizes these two stages through the solute distribution process, helping to further strengthen them.
