Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. This combination of elements provides excellent resistance to a wide range of corrosive environments. Alloy 825 is exceptionally resistant to sulfuric and phosphoric acids. It is also highly resistant to stress corrosion cracking and pitting.

ToggleThese characteristics make it a popular choice for instrumentation tube fittings, which are used in chemical processing, nuclear power reprocessing, acid production, propeller shafts, and oil and gas well piping. The material can also withstand the high temperatures encountered in these applications. In addition, it has good resistance to creep rupture and stress fatigue.
Forged fittings, including elbows, tees, and couplings, are available in a variety of shapes and sizes. The most common type is a union, which connects two tubes or pipes in a system. This type of fitting is popular in chemical processing and other industrial applications because it can be easily disassembled for maintenance purposes. Incoloy 825 is an ideal material for this type of forged tube fitting because it can withstand the pressure of chemical and hydrocarbon fluids.
The strength of Incoloy 825 forged fittings is due to its high levels of nickel and chromium. The material is also designed to resist oxidation and carburization, making it a good choice for high-temperature environments. It has excellent resistance to reducing and oxidizing acids, as well as chloride solutions. It is also highly resistant to abrasion and wear, making it a good option for heavy-duty applications.
Incoloy 825 forged fitting are also solid and reliable. They can be welded easily and are often used in chemical processing, power generation, and offshore petrochemical and oil & gas production. They are also commonly used in medical equipment and pharmaceutical manufacturing because they can withstand sterilization temperatures without becoming deformed or corroded.
