1. What are the primary applications of Monel 411 / N05502 alloy pipes?
Answer:
Monel 411 (N05502) pipes are mainly used in aerospace, chemical processing, marine, and high-stress industrial applications.
They are suitable for environments requiring high strength combined with excellent corrosion resistance, such as seawater, acidic solutions, and high-pressure systems.
2. What is the chemical composition of Monel 411 / N05502?
Answer:
Nickel: 63%
Copper: 28–34%
Iron: 2.5%
Manganese: 2%
Aluminum + Titanium: ~0.85–1.5% (for age-hardening)
Carbon, Silicon, and trace elements: small amounts
The alloy is age-hardenable, giving it superior mechanical strength compared to Monel 400.
3. What are the mechanical properties of Monel 411 pipes?
Answer:
Tensile strength: 827–965 MPa
Yield strength: 414–621 MPa
Elongation: 20–30%
Hardness (Rockwell B): 87–95
These properties make it ideal for high-pressure, high-stress, and high-temperature applications.
4. What pipe dimensions are available?
Answer:
Outer diameter (OD): 6 mm – 610 mm
Wall thickness: 1 mm – 40 mm
Lengths: 6 m or 12 m standard; custom lengths are available
Pipes can also be polished or finished according to customer specifications.
5. What standards and certifications do Monel 411 / N05502 pipes comply with?
Answer:
Typically manufactured according to ASTM B622, ASTM B164, ASTM B165
Meets ASME/ANSI B36.19 and other international piping standards
Material certifications such as EN10204 3.1 / 3.2, ISO, and API are available upon request
