In this detailed overview, we will explore what Inconel 800/800H/800HT Plates are, their properties, advantages, and applications.
What are Inconel 800/800H/800HT Plates?
Inconel 800, Inconel 800H, and Inconel 800HT are part of the nickel-iron-chromium alloy family, renowned for their excellent strength and resistance to oxidation, carburization, and other forms of high-temperature corrosion. These alloys are primarily designed for service in extreme temperature environments, making them ideal for applications in petrochemical, chemical, and power generation industries.
Inconel 800 Plates: Standard version known for its good creep and rupture strength.
Inconel 800H Plates: Modified version with higher carbon content for improved creep and stress rupture properties at temperatures above 600°C.
Inconel 800HT Plates: Further optimized version with controlled carbon and titanium, aluminum contents for enhanced performance in extreme conditions.
