Inconel Bolts with World Wide
Shipping
Lightning Bolt has become a specialist in hard to find corrosion
resistant fasteners. Included in the anti-corrosion alloys is
Inconel. This alloy is a registered trademark of Special Metals
Corporation that refers to a family of austenitic
nickel-chromium-based superalloys, Inconel alloys are typically used
in high temperature applications.
It is often referred to in English as "Inco"
(or occasionally "Iconel"). Common trade names for Inconel include:
Inconel 625, Chronin 625, Altemp 625, Haynes 625, Nickelvac 625 and
Nicrofer 6020.
Inconel alloys are oxidation and corrosion resistant materials well
suited for service in extreme environments. When heated, Inconel
forms a thick, stable, passivating oxide layer protecting the
surface from further attack. Inconel retains strength over a wide
temperature range, attractive for high temperature applications
where aluminum and steel would succumb to creep as a result of
thermally-induced crystal vacancies (see Arrhenius equation).
Inconel's high temperature strength is
developed by solid solution strengthening or precipitation
strengthening, depending on the alloy. In age hardening or
precipitation strengthening varieties, small amounts of niobium
combine with nickel to form the intermetallic compound Ni3Nb or
gamma prime (γ'). Gamma prime forms small cubic crystals that
inhibit slip and creep effectively at elevated temperatures.
Inconel is often encountered in extreme environments. It is this
reason why fasteners, nuts, bolts, socket head cap screws, and
washers made of Inconel are commonly found in gas turbine blades,
seals, and combustors, as well as turbocharger rotors and seals,
electric submersible well pump motor shafts, high temperature
fasteners, chemical processing and pressure vessels, heat exchanger
tubing, steam generators in nuclear pressurized water reactors,
natural gas progressing with contaminants such as H2S and CO2,
firearm sound suppressor blast baffles, and Formula One and NASCAR
exhaust systems. Inconel is increasingly used in the boilers of
waste incinerators.
