What are the common inspection methods used to test Inconel 718 hex nuts?

Before putting it for ideal use case, it is very important for Inconel 718 hex nuts to be tested. This is done to ensure that no degraded performance is then shown. To eradicate this, below are some ideal methods of testing:

  • NDT or Non-destructive testing: Under this common and most favourable type of testing, we just try to evaluate the strength and integrity of the nut. We do this, without altering any property that is associated with the nut.
  • Eddy current testing: it is the most suitable method to find flaws or degraded properties. Under this test, we make use of electronic probes or electrons, which travels throughout the length of the material surface.
  • Ultrasonic testing: this testing method, utilizes ultrasonic waves to detect flaws or faults. The waves used are of high frequency and is transmitted into this nut.

There are many other test, but the evaluation of the above three methods helps you to give an accurate information on how well it performs.

Are Alloy 718 bolts suitable for structural applications?

Because they offer good resistance to corrosive environments, alloy 718 bolts is very much suitable for structural applications.
Such applications also require to deal with extreme temperature conditions, if needed. Adding to this, below are some structural applications where you would find utilizing this bolts:

  • Solutions which are caustic.
  • Used as an equipment in food handling.
  • Applications and structures who require general corrosion resistance scenarios.
Can DIN 2.4668 nuts with a protective coating be used in high-temperature applications?

You would see DIN 2.4668 nuts exhibiting excellent properties when elevated to higher temperature conditions.
For temperature between 600-9000C, these nuts can withstand stress upto 1400 MPa.

Adding to this, protective coating layer also provides a charm to the surface; in association to promising longevity. This also enhances the durability characteristics.
Another important thing that is seen is that at high-level temperatures, it shows excellent resistance to fatigue.
