In many industries, including those where extreme temperatures and environments are a concern, typically alloys simply don’t have the durability and resistance to stand up to the job. In these situations, Inconel, a superalloy, is often the best choice.
Inconel is used in submersible pumps, in gas turbines, chemical processing facilities, shipbuilding, military, and defense applications as well as in nuclear reactors. It is also used on cryogenic vessels and storage tanks as well as in natural gas processing plants. Inconel studs were used to secure the launch platform to the solid rocket booster for the Space Shuttle, and also just eight studs made of this superalloy supported the full weight of the Shuttle and explosives were used on launch to create separation.
The Advantages to Consider
All Inconel studs will have the same advantages, but different alloys will offer slightly different benefits. It is part of a family of alloys with a nickel-chromium base and austenitic properties.
Heating of Inconel speeds up natural passivation, creating a very thick layer over the surface that is very stable. It is highly resistant to corrosion and oxidation, which is why it is a superior option in shipbuilding and other marine construction applications.
It is also able to withstand high temperatures without the problem of creep. This combination means it can also resist pressure and forces and not deform, an essential consideration when weight and stresses will be an issue with the final product.
Despite its durability and natural strength, it is not difficult to form Inconel into studs and other components. It is an excellent choice as a superalloy for fabrication of more complex parts as well as simple components.
There are different options in composition and alloying materials used in different Inconel studs. Working with a fastener company with the expertise to help to select the correct alloy will be a critical factor and one that will address the specific needs for a particular job.
