Monel Bolts and Fasteners Manufacturer

Here at Smith Bullough, we offer Monel bolts and fasteners with short production lead times.

What is Monel?

A nickel-copper alloy, Monel offers high strength, weldability and excellent corrosion resistance in many environments, including seawater, hydrofluoric acid, sulphuric acid and alkalis.

Properties of Monel

At Smith Bullough, we use Monel 400 and Monel K-500 in the manufacture of our bolts and fasteners.

Monel 400

Monel 400 is tough over a wide range of temperatures, offering good mechanical properties at subzero temperatures and can be used in temperatures as high as 1000F.

Corrosion resistance is broadly similar to nickel, but Monel 400 offers higher maximum working pressures and temperatures alongside improved machining ability.

Monel K-500

Monel K-500 is a precipitation-hardenable nickel-copper alloy.

With the inclusion of aluminium and titanium, Monel K-500 offers increased strength and hardness when compared with Monel 400.

Excellent corrosion resistance means that Monel K-500 is well-suited to a range of industrial applications and is widely used in chemical and marine environments.
