Monel 400 is a versatile nickel-copper alloy with exceptional corrosion resistance in various environments. Monel 400 flanges from this alloy offer excellent mechanical properties and are extensively used in various industries.

Monel 400 is well known for its corrosion resistance and far exceeds the durability of many other metals in environments with sulfuric acid, hydrochloric acid, or seawater. Therefore, making it a perfect choice of material for flanges in the chemical processing, marine engineering, and offshore oil and gas sectors.

Monel 400 also possesses high strength and good ductility. It retains its mechanical properties over a wide temperature range, making it also suitable for cryogenic applications. The alloy is known for its resistance to stress corrosion cracking, making it highly reliable in demanding environments. These properties make Monel 400 flanges suitable for applications in industries like aerospace, power generation, and petrochemical.

Furthermore, Monel 400 exhibits excellent thermal conductivity and is resistant to high-temperature oxidation and thermal expansion. These characteristics make Monel 400 flanges suitable for heat exchangers, boiler feedwater heaters, and other thermal processing equipment applications.
