A Ni-Cu alloy with high strength and good corrosion resistance
- Excellent resistance to hydrofluoric acid
- Excellent resistance to sea water for marine applications
- High strength metal with good toughness at high temperatures
- Monel Grades: Alloy 400 and K500
Monel® flanges, like Monel 400 and K500, are made from a nickel-copper alloy and exhibit high strength, toughness and good corrosion resistance over a wide temperature range.
An outstanding characteristic of Monel flanges is that they offer exceptional resistance to hydrofluoric acid, a particularly tough acid to deal with,
in all concentrations up to the boiling point. For hydrofluoric acid applications Monel flanges are perhaps the most resistant of all commonly used specialty alloys.
Monel alloy 400 & K500 flanges also exhibit excellent corrosion resistance in marine applications and have reasonable corrosion resistance to sulfuric and hydrochloric acids under reducing conditions.
Monel K500 Flanges are over 2x as strong as Monel 400 flanges.
Because of these characteristics, Monel flanges are often found in marine and chemical processing applications.
The most common grades of Monel flanges are Monel 400 and Monel K500 .
