Particular Characteristics of Inconel Flanges:
Nickel-chromium-molybdenum alloys, such as Inconel flanges, are utilized for their high strength at high temperatures and superior corrosion resistance. Inconel flanges may be used in service temperatures as low as cryogenic and as high as 2200°F (982°C) because of their strong thermal stability. Inconel flanges can survive a wide range of highly corrosive situations thanks to their high alloy content. There is essentially little assault on Inconel flanges in moderate conditions, such as the air, seawater, neutral salts, and alkaline media. The combination of nickel and chromium provides resistance to oxidizing chemicals in more corrosive conditions, but the high nickel and molybdenum levels offer resistance to nonoxidizing situations.
Particular Characteristics of Incoloy Flanges:
Incoloy flanges are formed of a nickel alloy with iron and a lesser amount of nickel, not to be mistaken with Inconel. In terms of cost, Incoloy is more affordable than Inconel, but it has lower temperature and corrosion resistance tolerances. Generally speaking, Incoloy's oxidation, carburization, and creep resistance make it an excellent material for prolonged exposure to high-temperature conditions. Incoloy is a popular option in the oil and gas and power sectors due to its resistance to saltwater, brine, sour gas, and high chloride conditions at extreme temperatures.
