What are Nimonic 80A Pipe Fittings?

Nimonic 80A Pipe Fittings (UNS N07080) are nickel-chromium-based alloy fittings strengthened by the addition of titanium and aluminum. These fittings are specifically designed for high-temperature applications where strength and oxidation resistance are critical.

They offer:

  • Excellent resistance to high-temperature oxidation
  • High creep and rupture strength
  • Resistance to thermal fatigue and scaling

Nimonic 80A is precipitation-hardened, making it ideal for applications involving prolonged exposure to elevated temperatures.


Key Features of Nimonic 80A Pipe Fittings

  • Outstanding high-temperature strength
  • Excellent resistance to oxidation and scaling
  • High resistance to creep and stress rupture
  • Good fatigue resistance
  • Excellent mechanical stability
  • Reliable performance in extreme heat conditions
  • Long service life in critical applications

Chemical Composition (%)

Typical composition includes:

  • Nickel (Ni): Balance (~70% min)
  • Chromium (Cr): 18 – 21%
  • Iron (Fe): ≤ 3%
  • Titanium (Ti): 1.8 – 2.7%
  • Aluminum (Al): 1.0 – 1.8%
  • Carbon (C): ≤ 0.10%
  • Manganese (Mn): ≤ 1%
  • Silicon (Si): ≤ 1%
  • Copper (Cu): ≤ 0.2%

Role of Alloying Elements

  • Nickel: Provides high-temperature strength and corrosion resistance
  • Chromium: Enhances oxidation resistance
  • Titanium & Aluminum: Enable precipitation hardening and improve strength
  • Iron: Adds structural stability

Mechanical Properties

Nickel 200

  • Tensile Strength: 850 – 1200 MPa
  • Yield Strength: ≥ 600 MPa
  • Elongation: ~20 – 30%
  • Hardness: Up to 250 HB
  • Density: 8.19 g/cm³

These properties ensure durability under extreme thermal and mechanical stress.

Physical Properties

  • Melting Range: 1320 – 1365°C
  • Modulus of Elasticity: 210 GPa
  • Thermal Conductivity: 11.7 W/m·K
  • Electrical Resistivity: 1.1 µΩ·m
  • Thermal Expansion: 14.0 µm/m°C

Corrosion & Oxidation Resistance

Nimonic 80A pipe fittings offer excellent resistance to

  • High-temperature oxidation
  • Scaling in furnace environments
  • Thermal fatigue
  • Stress rupture at elevated temperatures

They perform exceptionally well in environments involving heat and oxidation rather than aggressive chemical corrosion.


Heat Treatment

Nimonic 80A is precipitation hardened through controlled heat treatment:

  • Solution Treatment:1080°C followed by rapid cooling
  • Aging (Precipitation Hardening):700 – 800°C

This process enhances strength and creep resistance.


Weldability

Nimonic 80A pipe fittings offer good weldability with proper techniques:

  • TIG (GTAW)
  • MIG (GMAW)
  • SMAW

Welding Recommendations

  • Use matching filler materials
  • Control heat input
  • Pre-clean surfaces thoroughly
  • Post-weld heat treatment may be required

Machinability

Due to high strength and work-hardening characteristics:

  • Use carbide tools
  • Maintain low cutting speeds
  • Apply sufficient coolant
  • Avoid excessive heat
