What is Inconel 718 fasteners ? Do you provide samples of for testing and evaluation?

A fastener which is composed of high chromium and molybdenum content is a Inconel 718 fasteners. They show excellent corrosion resistance to wide range of environments.
Adding to this, excellent yield and tensile strength characteristics are exhibited.

When exposed to elevated temperatures up to 13000F, creep-rupture properties are seen. When comparing with other graded, it shows excellent mechanical properties, because aluminium, cobalt and titanium can also be added.
No need to worry if you are facing confusion on purchasing this product.

Hilton steel, where we have our experienced team, help customers to meet their standards.
Adding to this, yes, you can get the samples, so that you can use it for some time and then take accurate decisions on purchasing it. This helps the customer to be confident on the product too.

Inconel 718 fasteners

Manufacturer of ASTM B637 UNS N07718 Bolts and Hex Nuts in India as Per ASTM B637

What applications are Inconel 718 bolts used for?

Inconel 718 bolts, are one of the highly recommended hardening fasteners for industries because of its corrosion resistance and extreme tolerance characteristics. Considering this and many other properties that it offers, below are some industries, that demand for such fasteners:

  • For scenarios where temperature conditions are extreme, it is widely demanded by the chemical processing plants.
  • Another use case is seen in scenarios, where high level pressure is a critical factor. Considering this, industries using pressure vessels and boiler demand for it.
  • Nuclear power plants also widely demand for 718 graded bolts, thanks to the strength characteristics that it delivers. It helps to withstand extreme conditions.
  • Aeronautics, where high pressure and temperature are the most critical factor. Along with this, they also demand it because of the corrosion resistance behaviour.

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.
