- Commodity name: Incoloy 800/800H/800HT (US N08800/US N08810/US N08811)
800H is a face-centered cubic lattice structure. The very low carbon content and the increased Ti : C ratio increase the stability of the structure and the maximum resistance to sensitization and intergranular corrosion. A low-temperature annealing of around 950 ° C. ensures a fine-grained structure.

metallographic structure
800H is a face-centered cubic lattice structure. The very low carbon content and the increased Ti : C ratio increase the stability of the structure and the maximum resistance to sensitization and intergranular corrosion. A low-temperature annealing of around 950 ° C. ensures a fine-grained structure.
Scope of application
1. Nitric acid condenser resistant to nitric acid corrosion
2. Steam heat pipe good mechanical properties
3. Good mechanical properties of the heating element tube For applications up to 500°C, the alloy is supplied in the annealed state.
