Alloy 825

Nickel alloy 825, also known as Incoloy 825, is a nickel-iron-chromium alloy with additional elements such as molybdenum, copper, and titanium.

It is designed to offer excellent resistance to a wide range of corrosive environments, particularly those involving harsh chemicals, acids, and high temperatures. Nickel alloy 825 is part of the Incoloy family of alloys developed by Special Metals Corporation.

One of the primary advantages of alloy 825 is its exceptional resistance to various corrosive environments, including sulfuric acid, phosphoric acid, sulfur-containing gases, and seawater. It is especially well-suited for applications in chemical processing, oil and gas, and marine industries.
