Material Properties & Advantages
Chemical Composition: Nickel (min 62%), Molybdenum (26-30%), Low Carbon (max 0.02%)
Hastelloy B-2 round bars excel due to their unique chemical composition and microstructural stability. Molybdenum forms a dense protective oxide layer that prevents oxidation and chemical attack, with self-healing properties that restore protection if damaged.
Key mechanical properties include:
  • Tensile Strength: 690 MPa (100 ksi) minimum
  • Yield Strength: 310 MPa (45 ksi) minimum
  • Elongation: 40% in annealed state
  • Temperature Resistance: Up to 1093°C (2000°F)
  • Cryogenic Performance: Excellent ductility and toughness
