What are the characteristics of Incoloy 825?

Incoloy alloy 825 (UNS N08825, W.Nr. 2.4858) is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. The nickel content is sufficient for resistance to chloride-ion stress-corrosion cracking. The nickel, in conjunction with the molybdenum and copperto provide high levels of corrosion resistance to both moderately oxidizing and moderately reducing environments. The molybdenum also aids resistance to pitting and crevice corrosion. The alloy’s chromium content confers resistance to a variety of oxidizing substances such as nitric acid, nitrates and oxidizing salt. 

The Alloy 825 has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. It is especially resistant to sulfuric and phosphoric acids. The titanium addition serves, with an appropriate heat treatment, to stabilize the alloy against sensitization to intergranular corrosion. As an austenitic, nickel-base alloy, the material is ductile over a wide range of temperatures from cryogenic to well in excess of 1000°F (538°C). Fabrication of Alloy 825 is typical of nickel-base alloys, with the material readily formable and weldable by a variety of techniques.

Copper additions are well-known to improve resistance to reducing environments, such as sulphuric acid. This property is also exploited in Ferralium 255 (containing 2% copper additions) and the much more highly alloyed Alloy 20 (3-4% copper) to great effect. Although the nickel content is lower than the likes of Inconel 625 and Inconel 718, it is still sufficient to impart resistance to stress corrosion cracking (SCC) in chloride-containing environments. The increased chromium content ensures good resistance to oxidising environments such as nitric acid, whilst the molybdenum additions are well-known to improve pitting corrosion resistance.

The mechanical properties of Inconel 825 are relatively constant from very low temperatures (considered cryogenic i.e. -150degC) up to 540degC (100degF). Above this temperature there is the possibility of undesirable microstructural phase changes that significantly reduce impact toughness and elongation.

What are the uses of Incoloy 825 products?

As a leading Chinese Incoloy alloy supplier, JN Alloy manufactures and produces different sizes of Incoloy Alloy 825 Pipes, Plates, Bars, Fittings, Forgings, Flanges, Fasteners and can customize suitable products for you according to customer needs. Incoloy 825 is a high-performance nickel-iron-chromium alloy with additional elements like molybdenum, copper, and titanium. It is known for its exceptional resistance to corrosion, particularly in aggressive and corrosive environments, making it highly valued in various industrial applications.Due to these remarkable properties mentioned above, Incoloy 825 is used in a wide range of industries and applications, including:

Aerospace: Nickel alloys are a natural choice within the aerospace industry. Engine parts, in particular, are exposed to high temperatures and high pressure. Materials need to be able to withstand this environment and retain their strength and integrity. Nickel alloys exhibit low expansion at these high temperatures, offer creep resistance under high-stress conditions, and are corrosion resistant.

Chemical Processing: Incoloy 825 products are suitable for chemical processing applications involving corrosive chemicals, acids, and solvents. They are used in equipment such as reactors, heat exchangers, and piping systems. As they are resistant to corrosion and stress corrosion cracking.

Oil & Gas: Superalloys such as Incoloy 825 are utilised for the separation of extracted fluids in the processing systems for liquefied natural gas production. This material offers outstanding fatigue and thermal-fatigue strength, as well as good oxidation resistance, high tensile, creep and rupture strength, and excellent weldability. It’s often employed to line steel transfer piping in sour gas and gas extraction equipment.

Power Generation: The power industry includes hydropower, coal power, gas power, and nuclear power. In addition to hydropower, other power generation methods require the support of high-temperature materials. Among them, nuclear power is one of the most widely used power generation methods of superalloys. In addition to the extreme high temperature inside the nuclear reactor, there is also a very harsh radiological environment. This makes Incoloy 825 alloy an irreplaceable role in the composition of nuclear reactors.

Pollution & Waste:The waste in the industrial production process is generally treated by incineration. The temperature during incineration is extremely high and some waste materials are extremely corrosive. The Incoloy 825 alloys we manufacture have superior high-temperature corrosion resistance, and provide guaranteed solutions for waste treatment in petroleum refining, natural gas processing, pharmaceutical, medical and other industries.
