Monel Fasteners
Monel Nuts, Bolts, and Fasteners
Atlanta Rod and Manufacturing provides customers with high quality Monel nuts, bolts, and fasteners, all known for their outstanding resistance to corrosion. These are among the highest quality products available in today’s marketplace.
A trademark of the Special Metals Corporation, Monel products are part of a unique series created primarily of nickel and copper. Monel hardens quickly and is difficult to machine, needing to be worked at slow speeds for best results. Monel 400 hex bolts, studs, and fasteners have a hardness of 65 Rockwell B, electrical conductivity at about 3.4 percent IACS, and a specific gravity of 8.83. It is easily fabricated and is strengthened by cold work.
Monel K500 adds small quantities of titanium and aluminum for extra strength and resistance. Thanks to its age hardening, Monel K500 can maintain strength in extreme temperatures ranging from minus 423 degrees to 1200 degrees Fahrenheit. It also maintains its non-magnetic quality to a range of minus 210 degrees Fahrenheit.

Benefits
Both Monel 400 and Monel K500 are used in a variety of applications. It has demonstrated superior strength and durability, even over a wide range of extreme or rapidly changing temperatures, and is resistant to many corrosive environments that other materials cannot withstand.
Thanks to superior resistance to corrosion, marine applications are common. Monel is used for gasoline tanks, water tanks, and underwater projects and is used in shackle seizures in recreational boating. It is also used as the material for valves in some high quality musical instruments, including French horns, tubas, euphoniums, and other members of the brass family.
In the aerospace industry, Monel is a popular choice because of its outstanding ability to resist stress and heat created by aerodynamic friction. Though Monel is denser and can be heavier than other materials, it maintains its shape even at high speeds. Even at extreme high temperatures, Monel retains its strength and resists cracking and stress fracture.
Monel 400, with its unique hardening qualities and mechanical properties (even at subzero temperatures), is an excellent choice for corrosive environments, especially chemical processing and marine applications. Unlike other components, Monel 400 has outstanding mechanical properties at extreme low temperatures. Even when cooled to the temperature of liquid hydrogen, it maintains its strength and does not become brittle.
Monel K500 is also particularly suitable for marine applications, in part because of its resistance to sour gas environments. It offers high strength and low corrosion rates. The Monel K500’s low magnetic permeability, combined with its superior strength and corrosion resistance has made it a top choice in the oil well surveying industry as well. In longtime exposure and cyclic tests, Monel K500 has a documented stability that led to its preferability for high precision applications, including gyros and other devices.
