ASTM B423

Inconel 825 Seamless Pipe and Tube

ASTM B423 Standards And Specifications

ASTM B423 specification covers Inconel 825 (UNS N08825)in the form of cold-worked and hot-finished seamless pipe and tube intended for general corrosive service.

ASTM B423 - Seamless Pipe and Tube

Astm B423 Seamless Pipe Tube

ASTM B423 Seamless Tube is a nickel-iron-chromium alloy with additions of copper, molybdenum and titanium. The alloy's chemical composition is designed to provide exceptional resistance to many corrosive environments. The nickel content is sufficient for resistance to chloride-ion stress corrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives outstanding resistance to reducing environments such as those containing sulfuric and phosphoric acids. The molybdenum also aids resistance to pitting and crevice corrosion. The alloy's chromium content confers resistance to a variety of oxidizing substances such as nitrates, nitric acid and oxidizing salts. The titanium addition serves, with an appropriate heat treatment, to stabilize the alloy against sensitization to intergranular corrosion. The resistance of Incoloy 825 to general and localized corrosion under diverse conditions gives the alloy broad usefulness. Applications include chemical processing, pollution control, oil and gas recovery, acid production, pickling operations, nuclear fuel reprocessing and handling of radioactive wastes.
