The key to Incoloy 800H's exceptional properties lies in its
chemical composition. It contains approximately 30% nickel, 19%
chromium, and 3% aluminum, along with trace amounts of other
alloying elements. This composition endows the alloy with excellent
resistance to a wide range of corrosive environments, including
acids, alkalis, and chlorides.
Incoloy 800H alloy plate's high-temperature strength and excellent
formability make it an excellent choice for components that must
withstand extreme temperatures and pressure. It maintains its
strength and ductility across a wide range of temperatures, making
it suitable for use in high-temperature applications.
Furthermore, the alloy's resistance to chloride stress corrosion
cracking (SCC) is a valuable attribute in environments where
chloride ions are present. This resistance is further enhanced by
the addition of titanium and niobium, which act as grain refiners
and strengthen the material's resistance to cracking.
Incoloy 800H alloy plate is commonly available in thicknesses
ranging from 1/4" to 1" and in widths up to 60". It can be supplied
in either annealed or cold-worked conditions, depending on the
specific application requirements.
The welding of Incoloy 800H alloy plate is crucial to ensure the
longevity and integrity of the material. Proper welding techniques
and filler metals that are compatible with the base material must
be used to avoid potential cracking and loss of corrosion
resistance.
In conclusion, Incoloy 800H alloy plate is a highly versatile
material that offers exceptional strength, corrosion resistance,
and operational performance. Its unique combination of properties
makes it an excellent choice for a wide range of demanding
applications across various industries.
