3 Categories of Fasteners that Remain Stable under Extreme Environments

Industrial fasteners made and supplied by the leading industrial fasteners manufacturers in India are used to hold together two or more objects in almost all types of industrial, commercial, and residential applications. For most applications, common fasteners made using stainless steel work wonderfully well but applications that involve extreme temperatures need some specifically manufactured industrial fasteners that many people might not have any idea about.

This blog discusses in detail different aspects associated with high-temperature fasteners that remain stable even under the most extreme environments:

What are high-temperature fasteners?

High-temperature fasteners are made and supplied by India’s largest industrial fastener manufacturers making use of metals that offer outstanding resistance essential to withstand extreme temperatures and other environmental impacts. These specific fasteners are not used to serve common fastening purposes but find applications in critical industries that include:

  • Semiconductor
  • Aerospace
  • Automotive, and
  • Oil/Gas.

High-temperature fasteners are designed and developed by the top industrial fasteners manufacturers in India to:

  • Withstand extreme environments involving high temperatures
  • Hold up the alternate phases or rounds of extreme cooling and heating causing no damage to themselves
  • Forestall the process of oxidation, corrosion, and rusting.

Why are common fasteners not appropriate for high-temperature applications?

The industrial fasteners that are manufactured using common alloys are not considered to be appropriate at all to apply in extreme environments. It is because when the temperature rises, common fasteners start expanding, and as a result, additional pressure impacts the hole the fastener was driven into. When the temperature gets back to normalcy, again a contraction occurs, making the fastener lose its grip inside the hole. 

3 Categories of High-Temperature Fasteners

Nickel Alloy Fasteners

The term alloy in the world of industrial fasteners made and supplied by India’s largest industrial fastener manufacturers refers to any material or substance that is a purposeful combination of at least two or more metals. It is also surprising to know that most metals utilized to manufacture different types of industrial fasteners are themselves alloys. Stainless steel is a wonderful example of an alloy that is composed of the materials such as nickel, iron, chromium, and a wide range of other elements. Be it corrosion resistance or melting points, different alloys or metal combinations have different qualities.

Alloys with more nickel are ideal materials for high-temperature fasteners

When it comes to the manufacturing and overall quality of fasteners to be used in extreme environments, most industrial fasteners manufacturers in India and around the globe make use of alloys that have a larger percentage of nickel. Such nickel-oriented alloys are well-known to offer outstanding resistance to the oxidation process that necessarily takes place in extreme environments. Oxidation is a kind of chain reaction that is responsible for developing rusting and different types of other corrosions in all iron-containing metals.

In high-temperature environments, corrosion is not the only issue that comes up. The higher the temperature, the more chances of a decrease in the strength of metal are there. This condition leads to untimely breakdown due to the strain of continued use. The fasteners made of nickel alloys by India’s largest industrial fastener manufacturers are capable of withstanding high temperatures and far better than their counterparts made of simple stainless steel.

Refractory Metal Fasteners

In the point above, we have discussed that fasteners made and supplied by the leading industrial fasteners manufacturers using nickel-oriented alloys are ideal for high-temperature applications. But there are furnaces in certain industries that generate temperature which even fasteners made of nickel alloys cannot resist. Refractory metal fasteners are considered to be an ideal choice when it comes to the fastening of any component in temperature above 2,000 degrees Fahrenheit. Refractory metals are well-known to have thousands of degrees higher melting points than metals like steel.

When it comes to the composition of refractory metals, they include substances such as:

  • Molybdenum
  • Niobium
  • Rhenium
  • Tantalum, and
  • Tungsten.

All these metals have incredible properties that come at a high cost, and the fasteners manufactured using these metals by India’s largest industrial fastener manufacturers find use in very specific applications. Apart from offering high melting points, all these above-mentioned metals are also exemplary when it comes to hardness and density. Refractory metal fasteners offer high stability and show no deformation when placed even under extreme stress.  

Ceramic Fasteners

It seems to be quite unbelievable that fasteners even manufactured using refractory metals by the leading industrial fasteners manufacturers cannot be considered the greatest ones when it comes to resisting the extreme heat in many industrial applications. The ceramic fasteners manufactured using either alumina or zirconia can withstand the following range of temperatures:

  1. Alumina fasteners made and supplied the leading industrial fasteners manufacturers in India can withstand the temperature of up to 3000 degrees Fahrenheit
  2. Zirconia fasteners can be stable even under the temperature of up to 4350 degrees Fahrenheit.

Highly resistant to deformations, chemical degradations, and corrosion

These attributes make ceramic fasteners the most suitable choice when it comes to applying them in high-temperature applications across industries. Apart from withstanding temperatures up to 4350 degrees Fahrenheit, ceramic fasteners are also well-known for offering a phenomenal resistance to different types of deformations, chemical degradations, corrosion, and rusting. Made and supplied by India’s largest industrial fastener manufacturers, the nature of ceramic fasteners is also non-conductive which makes them perfectly suitable for all types of high-temperature requirements.

How to select the right kind of high-temperature fasteners

The right kind of high-temperature fasteners must be selected based on the following:

  1. Mechanical properties
  2. Potential for post-fabrication treatments
  3. Cost-efficiency
  4. The range of temperatures
  5. How long the fastener will be exposed to extreme environments
  6. Whether the fasteners will be placed to confront the corrosive forces
  7. Whether the fastener will be facing any physical forces like vibration or shock.

Concluding Remarks

When it comes to the material suitability of the high-temperature fasteners made and supplied by India’s largest industrial fastener manufacturers, it all depends upon the nature of the application or what and where you need to fasten any specific components. Based on the above described 3 categories of high-temperature fasteners, you can identify your needs according to the temperature range of your furnace.
