ASTM B409 Alloy 800H Plate UNS N08810 Hot Rolled Plate Sheet 0.6 - 20.0mm Thickness

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.
