What are AL-6XN Pipe Fittings?

AL-6XN (UNS N08367) is a super austenitic stainless steel alloy with high levels of chromium, nickel, molybdenum, and nitrogen. It is specifically developed for use in highly corrosive environments, particularly those containing chlorides.

AL-6XN pipe fittings offer:

  • Exceptional resistance to pitting and crevice corrosion
  • Excellent resistance to chloride-induced stress corrosion cracking
  • High strength and durability

This alloy is often used as a cost-effective alternative to higher nickel alloys and titanium in certain applications.


Key Features of AL-6XN Pipe Fittings

  • Outstanding corrosion resistance in aggressive environments
  • High resistance to pitting and crevice corrosion
  • Excellent resistance to chloride stress corrosion cracking
  • High strength and durability
  • Good weldability and fabrication properties
  • Long service life in demanding conditions

This composition gives AL-6XN an excellent Pitting Resistance Equivalent Number (PREN), making it highly suitable for chloride-rich environments.


Chemical Composition (%)

Typical composition includes:

  • Nickel (Ni): 23.5 - 25.5%
  • Chromium (Cr): 20 - 22%
  • Molybdenum (Mo): 6 - 7%
  • Nitrogen (N): 0.18 - 0.25%
  • Carbon (C): ≤ 0.03%
  • Manganese (Mn): ≤ 2%
  • Silicon (Si): ≤ 1%
  • Copper (Cu): ≤ 0.75%
  • Phosphorus (P): ≤ 0.04%
  • Sulfur (S): ≤ 0.03%

Role of Alloying Elements

  • Nickel: Enhances corrosion resistance and toughness
  • Chromium: Provides oxidation resistance
  • Molybdenum: Improves resistance to pitting and crevice corrosion
  • Nitrogen: Increases strength and corrosion resistance

Mechanical Properties

  • Tensile Strength: ≥ 650 MPa
  • Yield Strength: ≥ 300 MPa
  • Elongation: ≥ 35%
  • Hardness: ~217 HB max
  • Density: 8.24 g/cm³

Physical Properties

  • Melting Range: 1320 – 1390°C
  • Modulus of Elasticity: 195 GPa
  • Thermal Conductivity: 13 W/m·K
  • Electrical Resistivity: 0.85 µΩ·m
  • Thermal Expansion: 16 µm/m°C

Corrosion Resistance

AL-6XN pipe fittings offer excellent resistance to:

  • Chloride-rich environments
  • Seawater and marine conditions
  • Pitting and crevice corrosion
  • Acidic chemical environments
  • Industrial brines and desalination systems

Heat Treatment

AL-6XN is typically solution annealed:

Solution Annealing:

  • Temperature: 1100 – 1150°C
  • Rapid cooling

This ensures optimal corrosion resistance and mechanical properties.


Weldability

AL-6XN pipe fittings offer good weldability:

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

Welding Recommendations

  • Use compatible filler materials
  • Avoid excessive heat input
  • Clean surfaces thoroughly
  • Perform post-weld cleaning

Machinability

Due to high alloy content:

  • Use carbide tools
  • Maintain low cutting speeds
  • Apply sufficient coolant
  • Avoid work hardening
