MONEL 400 (UNS N04400) Ni 66.5 Cu 31.5 Description

May be used to handle hydrochloric acid, but the presence of oxidizing salts will greatly accelerate corrosive attack. These rates are for carbide tools, Type B1127 for roughing, drilling and reaming. Transfer piping from oil refinery crude columns.


The material shall conform to the required mechanical propeties such as tensile strength, yield strength, elongation, and Rockwell hardness. Characteristics Corrosion resistance in an extensive range of marine and chemical environments. This specification covers rolled nickel-copper alloy UNS N plate, sheet, and strip. Machining Type Suggested starting rates are: The matreial shall conform to the required chemical composition for satm, copper, iron, manganese, carbon, silicon, and sulfur.

Monoethanolamine MEA reboiling tube. The material shall conform to the required grain size. Historical Version s – view previous versions of standard.

Link to Active This link will always route to the current Active version of the standard. Monel is a Nickel-Copper alloy, resistant to sea water and steam at high temperatures as well as to salt and caustic solutions.

It is asrm only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. This abstract is a brief summary of the referenced standard. This alloy is more resistant to nickel under reducing conditions and more resistant than copper under oxidizing conditions, it does show however better resistance to reducing media than oxidizing.

Sulfuric acid and hydrofluoric acid alkylation plants. Good resistance to sulfuric and hydrofluoric acids. Type C-3 for finishing.

ASTM B127 UNS NO4400

Resistance to neutral, alkaline and acid salts is shown, but poor resistance is found with oxidizing acid salts such as ferric chloride. It is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. Monel is characterized by good general corrosion resistance, good weldability and moderate to high strength.


Monel is widely used in the chemical, oil and marine industries. Please give us a Review. Heat exchangers in a variety of industries.

The alloy has been used in a variety of applications. Cladding for the upper areas of oil refinery crude columns. Dimensions such as plate, sheet, and strip thickness, width, or diameter, length, straightness, edges, squareness, and flatness shall be determined.

It has excellent resistance to rapidly flowing brackish water or seawater. Monel is a nickel-copper alloy with excellent corrosion resistance in a wide variety of media. Applications Feed water and steam generator tubing. Plant for the refining of uranium and isotope separation in the production of nuclear fuel. High Performance Alloys stocks and produces Monel in this grade in the following forms: Brine heaters, sea water scrubbers in tanker inert gas systems. Overview Monel is a Nickel-Copper alloy, resistant to sea water and steam at high temperatures as well as to salt and caustic solutions.

From pure water to nonoxidizing mineral acids, salts and alkalis. Propeller and pump shafts. Pickling bat heating coils. Excellent resistance to chloride ion stress corrosion cracking. The alloy is slightly magnetic at room temperature.
