Applications

High-Temperature Environments

: Widely used in applications involving exposure to high temperatures, such as heat treating equipment, chemical and petrochemical processing, nuclear power plants, and the paper pulp industry. For example, it can be used for components like pigtails, headers, collectors, manifolds, transfer piping, catalyst tubes, and quench system piping in steam/hydrocarbon reforming processes.

Corrosive Environments

: Suitable for use in various aqueous media and environments with oxidation, carburization, and sulfidation risks. It is resistant to stress corrosion cracking and can maintain its performance in harsh chemical environments.

Electrical Heating Elements

: Often used in the manufacturing of electric heating elements for water heaters, electric fryers, electric kettles, display cabinets, defrosting machines, and other similar appliances due to its excellent corrosion resistance in water and high-humidity environments.

Advantages

Excellent Corrosion Resistance

: The high nickel and chromium content provide outstanding resistance to oxidation, carburization, and various corrosive media, ensuring long-term stability and durability in harsh environments.

High-Temperature Strength

: Maintains good mechanical properties at elevated temperatures, including high tensile strength, creep resistance, and rupture strength, making it suitable for demanding high-temperature applications.

Good Fabrication and Welding Characteristics

: The alloy is readily formed, welded, and machined, which facilitates its use in a wide range of manufacturing processes and allows for the production of complex components.

Stable Austenitic Structure

: Its composition ensures a stable austenitic structure, which contributes to its good ductility and toughness, and helps to prevent embrittlement and cracking during service.
