Nickel alloy 825, also known as Incoloy 825, is a nickel-iron-chromium alloy enhanced with molybdenum, copper, and titanium to provide superior resistance to aggressive chemical environments. Developed as part of the Incoloy family by Special Metals Corporation, this alloy is engineered to withstand highly corrosive conditions, making it a preferred choice in industries where exposure to acids, high temperatures, and seawater is common.
One of the standout properties of nickel alloy 825 pipe is its ability to resist sulfuric acid, phosphoric acid, and sulfur-containing gases, ensuring long-term durability in demanding applications. Similarly, alloy 825 tube is widely used in chemical processing, oil and gas extraction, and marine industries, where its corrosion resistance and mechanical strength contribute to extended service life. Whether in condensers, hydraulic systems, or nuclear fuel processing, Incoloy 825 pipe provides exceptional performance under extreme conditions.
