What are the Inconel Washers?
Inconel washers, such as Inconel 600, 601, 625, 686, 718, and 725 washers, are nickel-chromium-molybdenum alloys known for their excellent strength and corrosion resistance at high temperatures. Inconel may be employed in service temperatures ranging from cryogenic to 2200°F (982°C) due to its strong thermal stability. Inconel washers’ high alloy content allows them to survive a wide range of harsh corrosive conditions.
Inconel washers are almost impervious to assault in moderate conditions such as the atmosphere, seawater, neutral salts, and alkaline media. The combination of nickel and chromium gives resistance to oxidizing chemicals in more severe corrosive situations, whilst the high nickel and molybdenum concentration provides resistance to nonoxidizing environments.
Inconel washers are often used in chemical processing, aerospace, maritime, electronics, and oil and gas because they provide an excellent blend of corrosion resistance, thermal stability, toughness, and strength.
Grades of Inconel Washers
Inconel 600 Washer
Alloy 600, also known as UNS N06600, is a nickel-chromium alloy that resists carburization and oxidation up to 2000°F. Inconel 600 has a long history of usage in the heat treatment industry, and it has good resistance to dry Cl2 and HCl gases at relatively high temperatures.
Inconel 601 Washer
Even under extreme temperature cycling, Inconel 601, UNS N06601, is extremely resistant to oxidation up to 2200°F. The alloy offers good high-temperature strength and maintains its ductility even after extended usage. Under oxidizing circumstances, Inconel 601 alloy offers strong hot corrosion resistance.
Inconel 625 Washer
The workhorse of the Inconel family, Inconel 625, UNS N06625, is one of the most frequent grades. It has a strong creep-rupture strength and can withstand temperatures up to 1800°F (982°C). Inconel 625 Washers is resistant to a wide range of extremely corrosive conditions, including hot saltwater, scrubber environments, and reducing acids, and it is notably resistant to pitting and crevice corrosion.
Inconel 686 Washer
Alloy 686, also known as UNS N06686, is a corrosion-resistant alloy that may be used in a variety of harsh conditions. Chemical processing, pollution control, pulp, and paper manufacture, and the treatment of industrial and municipal waste all employ the alloy in the harshest settings.
Inconel 718 Washer
The most prevalent grade of the hardenables Inconel is Inconel 718 (UNS N07718). This precipitation-hardened nickel-chromium alloy has excellent corrosion resistance as well as strong strength at high temperatures. The alloy is nearly twice as strong as Inconel 625, with outstanding creep-rupture strength up to 1300°F (700°C) and useable temperatures up to 1800°F (982°C). Gas turbines, rocket motors, spaceships, nuclear reactors, pumps, and tools all require Inconel 718.
Inconel 725 Washer
Alloy 725, also known as UNS N07725, is a nickel-chromium-molybdenum-niobium age-hard enable alloy with approximately the same corrosion resistance as Inconel 625 but twice the strength. To obtain high ductility and toughness, this alloy undergoes heat treatment to increase its strength. Hydrogen embrittlement and stress-corrosion cracking are not a problem for this alloy.
Inconel X750 Washer
The precipitation hardened alloy X-750, UNS N07750, is noted for its corrosion resistance and high-temperature oxidation resistance up to 1300°F. With the inclusion of titanium and Aluminium, this alloy is comparable to Alloy 600 but allows for precipitation.
