What are MP35N Bars?
MP35N Bars are manufactured from a precipitation-hardenable cobalt-nickel-chromium-molybdenum alloy that offers one of the highest strength-to-corrosion-resistance combinations available among engineering alloys. The alloy remains stable under extreme temperatures, corrosive chemicals, seawater, and high-pressure environments.
Our Cobalt nickel MP35N bars are available in several forms including round bars, hex bars, flat bars, square bars, forged bars, and precision-machined bars. These products are supplied according to customer specifications while meeting stringent industry standards.
As reliable MP35N bar manufacturers, we understand that industries require consistent quality, dimensional accuracy, and complete material traceability. Therefore, every bar is carefully inspected before dispatch.
MP35N Superalloy Bar Properties
One of the biggest advantages of MP35N is its unique combination of mechanical strength and corrosion resistance.
Key MP35N bar properties include:
- Extremely high tensile and yield strength
- Outstanding resistance to stress corrosion cracking
- Excellent fatigue performance
- High resistance to seawater corrosion
- Superior resistance to hydrogen embrittlement
- Excellent wear resistance
- Good ductility and toughness
- Non-magnetic in many service conditions
- Excellent resistance to chloride environments
- Long service life with minimal maintenance
These outstanding MP35N superalloy bar properties make the alloy suitable for critical engineering applications where failure is not an option.
