Incoloy Alloy 825 Plate
INCOLOY® Alloy 825 Plate (UNS N08825/W.Nr. 2.4858) is a composite alloy consisting of nickel, iron, chromium, and various add-ons including molybdenum, copper, and titanium. The chemical composition of this alloy is specifically created to offer outstanding resistance against a variety of corrosive surroundings. The presence of nickel in this alloy is adequate to resist stress-corrosion cracking caused by chloride ions. Additionally, the combination of nickel, molybdenum, and copper provides excellent protection against reducing environments, including those containing sulfuric and phosphoric acids. Additionally, molybdenum plays a crucial role in enhancing the ability of materials to withstand pitting and crevice corrosion. The presence of chromium in the alloy provides protection against oxidizing elements like nitric acid, nitrates, and oxidizing salt by enhancing the material's resistance to them. With the aid of proper heat treatment, the inclusion of titanium helps to prevent the alloy from becoming sensitized to intergranular corrosion, thereby stabilizing it.Â
Â
UNS N08825 is specifically engineered to offer extraordinary resistance against a wide range of corrosive settings. UNS N08825 is similar to alloy 800 but features enhanced resistance to corrosion in aqueous environments.Â
It exhibits outstanding resistance to reducing and oxidizing acids, stress-corrosion cracking, and localized forms of corrosion, including pitting and crevice corrosion.Â
The material displays favorable mechanical properties that maintain consistency across both normal and elevated temperatures, reaching up to approximately 1000°F.
It permits for pressure-vessel use at wall temperatures up to 800°F.
It has outstanding capacity to withstand the effects of both reducing and oxidizing acids.
The material has impressive durability against stress-corrosion cracking.
It also has acceptable ability to withstand localized forms of corrosion, such as pitting and crevice corrosion.
And it is highly resilient against the harmful effects of sulfuric and phosphoric acids.
