Monel Hex Bolt

Monel Hex Bolt description

The Monel coating that covers Fastener Solutions’ hex head cap screws allows them to be heat resistant and corrosion resistant. This Monel alloy also provides salt water and heat discoloration resistance. Our Monel fasteners are made with the choice of two different types of Monel, depending on your application requirement needs.

Monel hex bolts 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 bolts 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 hex head bolts are perhaps the most resistant of all commonly used specialty alloys.

Monel screws, 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 screws 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 screws are perhaps the most resistant of all commonly used specialty alloys.

Monel 400 has a wonderful corrosion resistance by many reducing media such as sulfuric and hydrochloric acids. Generally, Monel 400 has a more resistantance to corrosion by oxidizing media than higher copper alloys. Monel 400 resists pitting and stress corrosion cracking in most fresh and industrial waters. It has good resistance in flowing seawater, but under stagnant conditions, pitting and crevice corrosion is induced. Monel 400 is probably the most resistant to hydrofluoric acid in all concentrations up to the boiling points. Monel 400 is not able for its toughness, it does not show embrittlement tendency at cryogenic temperatures. It is work hardenable.
