MONEL 400 (UNS N04400) Ni 66.5 Cu 31.5 Description

Type C-3 for finishing. Cladding for the upper areas of oil refinery crude columns.

Propeller and pump shafts. Request quote on this grade. Aeration however will result in increased corrosion rates.

ASTM B – 98 Standard Specification for Nickel-Copper Alloy (UNS N) Plate, Sheet, and Strip

The alloy is slightly magnetic at room temperature. Dimensions such as plate, sheet, and xstm thickness, width, or diameter, length, straightness, edges, squareness, and flatness shall be determined. The material shall conform to the required mechanical propeties such as tensile strength, yield strength, elongation, and Rockwell hardness.


High Performance Alloys stocks and produces Monel in this grade in the following forms: Excellent resistance to chloride ion stress corrosion cracking.

Monel is widely used in the chemical, oil and marine industries. Work Item astmm – proposed revisions of this standard. Monoethanolamine MEA reboiling tube. Sulfuric acid and hydrofluoric acid alkylation plants.

Good mechanical properties from subzero temperatures up to about C. Transfer piping from oil refinery crude columns.

Historical Version s – view previous versions of standard. Heat exchangers in a variety of industries.

Pickling bat heating coils. 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. Plant for the refining of uranium and isotope separation in the production of nuclear fuel.

It has excellent resistance to rapidly flowing brackish water or seawater. May be used to handle hydrochloric acid, but the presence of oxidizing salts will greatly accelerate corrosive attack.
