Description

NiCr21Mo (2.4858), commonly known as Alloy 825, is a nickel-iron-chromium alloy with molybdenum and copper additions, offering exceptional corrosion resistance in both oxidizing and reducing environments. This material is particularly effective against pitting, crevice corrosion, and stress corrosion cracking in aggressive chemical and marine settings, including exposure to sulfuric and phosphoric acids. Alloy 825 is widely used in industries such as chemical processing, marine engineering, and oil and gas for applications like heat exchangers, piping systems, and storage tanks. At Rosswag, we process NiCr21Mo (2.4858) using advanced open-die forging and precision machining techniques, ensuring high-quality components that meet stringent performance standards. With its excellent mechanical properties and superior corrosion resistance, NiCr21Mo (2.4858) is a reliable choice for demanding industrial environments.
