One of the highest strength alloys available to industry
- Extreme high strength properties up to 300 ksi ultimate tensile.
- Good in moderately elevated temperatures of 800°F.
- Moderate corrosion resistance.
- MP35N chemisty, specs, and heat treatments.
MP35N nuts and lock nuts are known for their extraordinary strength and are the strongest nuts we offer at Extreme Bolt. MP35N nuts owe their extraordinary strength to a unique alloy combination of nickel, cobalt, chrome and molybdenum and have ultimate tensile strengths that range from 227 ksi to 294 ksi (with age hardening).
Beyond the strength of MP35N nuts, they are also exhibit good corrosion resistance and can resist most mineral acids, hydrogen sulfide, seawater and salt spray environments.
MP35N nuts are also resistant to high temperature oxidation and could operate in environments up to 800°F and still maintain much of its strength.
Applications where MP35N nuts are often found are: aerospace, defense, marine, chemical processing, oil and gas and medical.

Heat Treating & Aging: MP35N is usually supplied in heat treated and cold drawn condition AMS 5844. In this state the MP35N can be worked into the desired fastener form and aged to the AMS 5845 specification. Once aged, the MP35N material could achieve it full strength potential.
MP35N Specifications: AMS 5844, AMS 5845, AMS7468, ASTM F562, NACE MR0175
