Details description
Chemical Composition
Primarily composed of nickel (Ni) and copper (Cu), with nickel content ranging from 63% to 70% and copper content from 28% to 34%. It also contains small amounts of other elements such as iron (Fe), manganese (Mn), silicon (Si), carbon (C), and sulfur (S).
Mechanical Properties
Tensile strength ≥450MPa, yield strength ≥170MPa, elongation ≥30%, hardness typically between HB 110-215 (varies depending on processing conditions).
Performance Characteristics
Excellent corrosion resistance: Exhibits superior resistance to hydrofluoric acid and fluorine gas, making it one of the few alloys suitable for fluoride environments. It also demonstrates good corrosion resistance in acidic media such as sulfuric and hydrochloric acids, for example, in sulfuric acid concentrations below 85%. Furthermore, it resists corrosion from seawater, saltwater, atmospheric conditions, and organic compounds. It offers better corrosion resistance in seawater than copper-based alloys and generally does not experience stress corrosion cracking.
Good Processing Properties
Possesses excellent cold and hot working properties, allowing for processing into various shapes through rolling, forging, and drawing. It also exhibits good machinability.
Other Properties
It features high strength and good toughness, along with moderate thermal and electrical conductivity. It maintains good mechanical properties even in low-temperature environments.
Standards
ASTM B127, ASME SB-127, AMS 4554, JIS NW4400, etc.
Product Forms
Common forms include seamless pipes, plates, bars, forgings, flanges, rings, welded pipes, strips, and wires. It can also be processed into various components as needed.
Applications
Widely used in marine engineering, such as ship heat exchangers, seawater desalination equipment, propeller shafts, and water pumps. It is also used in the chemical and petrochemical industries, including salt production equipment, marine and chemical processing equipment, gasoline and water tanks, and components of chemical equipment that come into contact with corrosive media such as hydrofluoric acid.
