What is Inconel 800 / 800H / 800HT Flanges ?
Inconel 800/800H/800HT flanges are the most ductile and strong flanges in the metal industry. These flanges are commonly made of high quality raw material and alloys in order to maintain its ductility and durability. Inconel 800/800H/800HT flanges are commonly made for the purpose of providing excellent services and resistance from various chemical and physical processes.
Inconel 800/800H/800Ht grade is made of elements like nickel-chromium-iron. The grade also provides excellent protection from all types of chemical and mechanical reactions. These inconel 800/800H/800Ht flanges are commonly used as boilers. These flanges are used to help and support an object. It is also used as a connector between two or more pipes. Flanges are commonly used for creating a temporary/permanent joint between two or more pipes, valves or pumps together. Inconel 800/800H/800HT flanges provide excellent resistance from oxidation and corrosion.

Inconel 800/800H/800Ht flanges are highly ductile and they provide excellent durability. Inconel 800/800H/800HT provides high resistance from procedures like corrosion, crevice corrosion and stress cracking. The tensile and yield strength of these flanges is extremely high which is why these flanges are being used in various industries for a variety of purposes.
Inconel 800/800H/800Ht supports welding and annealing; it also supports other heat treatments. Hence, it is considered as an ideal grade for the application in pharmaceutical, petrochemical, pulp and paper making industries.
