Incoloy 800/800H/800HT/825 Flanges Manufacturers

Incoloy 800/800H/800HT/825 Flanges
Delta Steel is a highly respected company specializing in providing Incoloy 800/800HT/825 Flanges as a supplier, exporter, stockist, and manufacturer to customers worldwide at affordable prices. We offer these flanges in custom sizes and shapes based on client needs.
Incoloy 800/800HT Flanges are known for their strong design, durability, and high tensile strength. They are commonly used in heat exchangers, carburizing equipment, nuclear steam generators, processing pipes, and heat element sheathing. Made from nickel, iron, and chromium, Incoloy 800HT Flanges provide excellent high-temperature performance, thanks to the aluminum and titanium content. The combination of nickel and chromium also ensures superior resistance to oxidation.

Incoloy 825 is an iron-chromium-nickel alloy that also contains titanium, copper, and molybdenum. It offers better resistance to corrosion in water compared to the 800 alloys, although they are otherwise similar. This alloy is commonly used in pollution-control equipment, acid production, oil and gas piping, pickling equipment, and nuclear fuel reprocessing. It is available in various forms like plates, sheets, bars, wires, and weld wires.

Incoloy 800, 800HT, and 825 flanges each have unique properties. Incoloy 800 flanges offer good corrosion resistance in acidic environments, moderate resistance to sulfur-containing atmospheres, and strong resistance to carburization and oxidation at high temperatures. They also have excellent strength and creep-rupture properties at elevated temperatures.
Incoloy 825 flanges are highly resistant to phosphoric and sulfuric acids and perform well against both oxidizing and reducing acids. They offer good protection against crevice and pitting corrosion and maintain strong mechanical properties at both room and elevated temperatures, up to approximately 1000°F. Pressure walls can be used up to 800°F. The features of Incoloy 800HT flanges are similar to those of Incoloy 800.
To ensure the quality of Incoloy 800, 800HT, and 825 flanges, various tests are conducted, including hardness tests, flaring tests, intergranular corrosion tests, and flattening tests. The packaging depends on the size of the flanges, typically involving wrapping in jute fabric or plastic, with metal sheets used at bundle ends to prevent damage.
