Incoloy 908 Nickel Alloy Bar (UNS N09908)
Premium Incoloy 908 Alloy Bar Supplier for Extreme Environments
Lork Group supplies high-quality Incoloy 908 alloy bar (UNS N09908), a specialized age-hardenable nickel-iron alloy engineered for cryogenic and high-performance applications. This cobalt-free, low thermal expansion (CTE) alloy delivers exceptional strength, fracture toughness, and fatigue resistance, making it ideal for fusion reactors, superconducting magnets, and ultra-low-temperature environments.
Key Properties of Incoloy 908 Alloy Bar
- Low Coefficient of Thermal Expansion (CTE) – Maintains dimensional stability in extreme temperature fluctuations.
- High Tensile Strength & Toughness – Excellent mechanical properties at cryogenic temperatures.
- Fatigue Crack Growth Resistance – Withstands cyclic stresses in demanding applications.
- Metallurgical Stability & Weldability – Ensures structural integrity in complex fabrication processes.
- Resistance to Stress-Accelerated Grain Boundary Oxidation (SAGBO) – Prevents cracking during hot forming.
- Cryogenic Performance – Reliable operation down to -452°F (-269°C).
