Incoloy Tubing are nickel containing super alloys developed to execute excellent corrosion resistance. To give them extreme corrosive environmental resistance Incoloy Tubing are added with copper and titanium. General corrosion resistance is high in Inconel tubing.
Incoloy tubing have a stable austenitic structure. It also has sufficient amount of nickel content to give it chloride ion stress corrosion cracking resistance. The amount of molybdenum and chromium is varied to increase the immunity of Incoloy to reducing agents and acids. The addition of chromium to Incoloy tubing nitrates, oxidising salts, and nitric acid solutions. To make Incoloy tubing resistant to pitting and intergranular corrosion titanium is added to it. The alloy is capable of resisting sulphuric and phosphoric acid attacks, which makes its usable in such environments without much damage to its structure. Incoloy is also used in application such as chemical processing plants, tank trucks, phosphoric acid evaporators, electrostatic precipitator electrodes, propeller shafts, exhaust bellows, and marine exhaust systems. It is also termed as one of the most cost effective alloys with effective usage in constant sulphuric acid environments.
