| Description |
Carpenter MP35N alloy is a nonmagnetic, nickel-cobalt-chromium-molybdenum alloy possessing a unique combination of ultrahigh tensile strength (up to 300 ksi [2068 MPa]), good ductility and toughness, and excellent corrosion resistance. In addition, this alloy displays exceptional resistance to sulfidation, high temperature oxidation, and hydrogen embrittlement.
The unique properties of MP35N alloy are developed through work hardening, phase transformation and aging. If the alloy is used in the fully work hardened condition, service temperatures up to 750°F (399°C) are suggested. |
|
|
| Applications |
Because of its unique combination of properties, MP35N alloy has been used in a wide variety of applications.
It has been used in fasteners, springs, nonmagnetic electrical components and instrument parts in medical, seawater, oil and gas well, and chemical and food processing environments.
