Iranian Company Indigenizes Inconel Super Alloy with Extremely High Oxidation Resistance
“Inconel 601 is a nickel-chromium super alloy that shows good resistance to oxidation at high temperature. This alloy also has good resistance in aqueous environments and shows good creep resistance in general at high temperature. Other features of it are good mechanical strength and malleability. This alloy can be welded and machined,” said Mohammad Forouqi Moqaddam, the managing director of the knowledge-based company.
“The unique resistance of this alloy to oxidation up to 1200 degrees Celsius, even against fluctuations and thermal cycles, has made it widely used in the industry,” he added.
“This strategic super alloy is used as a clamp in the wall of all kinds of industrial furnaces, specially the wall of direct reduction furnaces due to the creep stresses there and high mechanical resistance at high temperature,” Forouqi Moqaddam said.
He underlined that Poulad Poushesh Avang Company enjoys a production capacity of 20 tons of Inconel super alloy annually.
Inconel is a nickel-chromium-based superalloy often utilized in extreme environments where components are subjected to high temperature, pressure or mechanical loads.
Inconel alloys are oxidation- and corrosion-resistant. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack.
Inconel retains strength over a wide temperature range, attractive for high-temperature applications where aluminum and steel would succumb to creep as a result of thermally-induced crystal vacancies. Inconel's high-temperature strength is developed by solid solution strengthening or precipitation hardening, depending on the alloy.
