What Are Inconel 800 Wires?

Inconel 800 Wires are nickel-iron-chromium alloy wires designed for high-temperature strength and excellent resistance to oxidation, carburization, and corrosion.

Alloy 800 (UNS N08800) maintains structural stability at elevated temperatures and resists scaling in oxidizing environments. It offers good resistance to stress corrosion cracking and performs well in prolonged high-temperature service.

Inconel 800 wires are widely used in applications requiring strength and corrosion resistance in environments up to approximately 1100°C.

Key Features of Inconel 800 Wires

  • Excellent resistance to oxidation and scaling
  • Good strength at elevated temperatures
  • Resistant to carburization and nitriding
  • Good resistance to stress corrosion cracking
  • Stable austenitic structure
  • Good weldability and formability
  • Non-magnetic in annealed condition

These features make Inconel 800 wires suitable for heat-intensive and corrosive environments.


Chemical Composition of Inconel 800

Element Composition (%)
Nickel (Ni) 30.0 – 35.0
Chromium (Cr) 19.0 – 23.0
Iron (Fe) 39.5 min
Carbon (C) 0.10 max
Manganese (Mn) 1.5 max
Silicon (Si) 1.0 max
Aluminum (Al) 0.15 – 0.60
Titanium (Ti) 0.15 – 0.60
Sulfur (S) 0.015 max
Copper (Cu) 0.75 max

Role of Key Elements

  • Nickel (Ni): Provides resistance to stress corrosion cracking
  • Chromium (Cr): Enhances oxidation and corrosion resistance
  • Iron (Fe): Maintains structural integrity
  • Aluminum (Al) & Titanium (Ti): Improve high-temperature stability

The balanced composition ensures strength and corrosion resistance in high-temperature environments.


Mechanical Properties of Inconel 800 Wires (Annealed Condition)

  • Tensile Strength: 520 MPa (min)
  • Yield Strength: 205 MPa (min)
  • Elongation: 30% (min)
  • Hardness: 170 HB (approx.)
  • Density: 7.94 g/cm³

Cold working increases strength and hardness while reducing ductility.


Physical Properties

  • Melting Range: 1350 – 1400°C
  • Modulus of Elasticity: 196 GPa
  • Thermal Conductivity: 11.5 W/m·K
  • Electrical Resistivity: 0.93 µΩ·m
  • Coefficient of Thermal Expansion: 14.4 µm/m°C

These properties ensure reliable performance under continuous heating and thermal cycling.


Corrosion & Oxidation Resistance

Inconel 800 wires offer good resistance to:

  • High-temperature oxidation
  • Carburization
  • Nitriding environments
  • Stress corrosion cracking
  • Sulfidation

The alloy performs well in both oxidizing and moderately reducing environments.


Heat Treatment

Inconel 800 is not precipitation hardenable and is typically supplied in annealed or cold-worked condition.

Annealing Process:

  • Heat to 980 – 1150°C
  • Rapid air cooling

Annealing restores ductility and relieves internal stresses.


Weldability

Inconel 800 wires exhibit good weldability:

  • Suitable for TIG (GTAW) and MIG (GMAW) welding
  • No preheating generally required
  • Matching filler metals such as ERNiCr-3 recommended
  • Post-weld heat treatment usually not necessary

The alloy maintains corrosion resistance in welded joints.


Machinability

Inconel 800 has moderate machinability.

Recommendations:

  • Use rigid setups
  • Employ sharp carbide tools
  • Maintain moderate cutting speeds
  • Apply adequate coolant
  • Minimize work hardening

Proper machining ensures dimensional accuracy and surface quality.
