Melting range | 1357-1385℃ |
Application: Chemical and petrochemical process piping, heat exchangers, furnace components, carburizing equipment, heating-element sheathing, and nuclear power steam-generator tubing.
Advantages: UNS N08800 has good rupture and creep strength and excellent resistance to oxidation, carburization and sulfidation at temperatures up to 816℃. It also resists general corrosion by many aqueous media. For Applications requiring higher stress rupture and creep properties, especially at temperatures above 816℃, UNS N08810 and UNS N08811 are recommended. UNS N08800 is readily formed, welded and machined.
