Monel® fasteners, 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 from cryogenic up to 1000°F. An outstanding characteristic of Monel fasteners 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 fasteners are perhaps the most resistant of all commonly used specialty alloys.
Monel alloy 400 & K500 fasteners also exhibit excellent corrosion resistance in marine applications and have reasonable corrosion resistance to sulfuric and hydrochloric acids under reducing conditions.
Because of these characteristics, Monel fasteners are often found in marine and chemical processing applications.
