Incoloy 825 screws are made of an alloy of titanium, copper, and molybdenum with nickel, iron, and chromium. High nickel alloy screws made of Incoloy UNS N08825 are resistant to high temperatures and can be used in a wide range of products. Alloys made of nickel known as Inconel alloys or superalloys have high resistance to corrosion, oxidation, carburization, pitting, crevice corrosion, and cracking at high temperatures.
Copper and molybdenum are also added to the nickel-iron-chromium alloy used to make Inconel 825 screws. To ensure a long service life, superior grade rust-resistant steel is used in the development of each piece of Inconel 825 screws. Inconel 825 can withstand temperatures as high as 1600 to 2150° F. Extreme resistance to reducing and oxidizing acids, stress-corrosion cracking, localized attacks such as pitting and crevice corrosion, as well as diverse environmental conditions, may be found in Inconel Din 2.4858 Screws.

These nickel steel Incoloy 825 Screws are used in a variety of industrial settings, such as chemical processing facilities, pollution control machinery, oil, and gas well pipes, nuclear fuel recycling, acid production, and pickling apparatus. These Incoloy Screws in these conditions frequently have good mechanical characteristics at both ambient and increased temperatures that can reach up to about 1000°F. The intergranular corrosion of Incoloy 825 is highly resistant to it. Incoloy 825 Screws are used in various applications, such as pressure vessels where the temperature can reach as high as 800°F, in addition to their outstanding corrosion resistance. This is because they are reasonably inexpensive and have a low cost of production.
