3. Excellent workability
Microstructure of Incoloy 800H:
800H has a face-centered cubic crystal structure. The extremely low carbon content and increased Ti:C ratio enhance the stability of the structure and its largerSensitivityChemical properties and intergranular corrosion resistance. Annealing at around 950°C ensures a fine-grained structure.
Withstanding long-term exposure to high temperatures
Excellent antioxidant, anti-sulfuration, and carbon penetration properties.
Adding carbon and annealing treatment provides higher creep and fracture resistance above 1100°F (600°C).
High-temperature corrosion-resistant
Process easily via standard methods
Easy-to-use products suitable for high-temperature environments, join/weld
Water resistance to corrosion at moderate temperatures
