Monel 405 Bolts with World Wide
Lightning Bolt is the industry leader in hard-to-find Monel 400
fasteners. This alloy is the free-machining version of MONEL alloy
400. A controlled amount of sulfur is added to the alloy to provide
sulfide inclusions that act as chip breakers during machining. Other
characteristics are essentially the same as those of MONEL alloy
This alloy is a Nickel-Copper alloy, resistant to sea water and
steam at high temperatures as well as to salt and caustic solutions.
Alloy R405 is a nickel-copper alloy with excellent corrosion
resistance in a wide variety of media. The alloy is characterized by
good general corrosion resistance and moderate to high strength. The
alloy has been used in a variety of applications. It has excellent
resistance to rapidly flowing brackish water or seawater. It is
particularly resistant to hydrochloric and hydrofluoric acids when
they are de-aerated. The alloy is slightly magnetic at room
temperature. The alloy is widely used in the chemical, oil and
marine industries. Due to its notable ability to resist corrosion, a
diverse amount of fasteners can be made from this alloy. Such
fasteners include: nuts, bolts, hex cap screws, washers, socket head
cap screws, and studs.
Corrosion resistance in an extensive range of marine and chemical
environments. From pure water to nonoxidizing mineral acids, salts
This alloy is more resistant to nickel under reducing conditions
and more resistant than copper under oxidizing conditions, it does
show however better resistance to reducing media than oxidizing.
Good mechanical properties from subzero temperatures up to about
Good resistance to sulfuric and hydrofluoric acids. Aeration
however will result in increased corrosion rates. May be used to
handle hydrochloric acid, but the presence of oxidizing salts will
greatly accelerate corrosive attack.
Resistance to neutral, alkaline and acid salts is shown, but poor
resistance is found with oxidizing acid salts such as ferric
Excellent resistance to chloride ion stress corrosion cracking.
*Due to sulfur addition for free machining, welding is not possible.
Brine heaters, sea water scrubbers in tanker inert gas systems.
Sulfuric acid and hydrofluoric acid alkylation plants.
Pickling bat heating coils.
Heat exchangers in a variety of industries.
Transfer piping from oil refinery crude columns.
Plant for the refining of uranium and isotope separation in the
production of nuclear fuel.
