Is Inconel the same as nickel alloy?
Let's start with nickel
Nickel is an extremely adaptable element with a variety of useful properties, such as heat resistance, corrosion resistance, electrical and magnetic properties, and low expansion levels. As an added bonus, it also bonds easily to many different alloys.
Nickel's adaptability and natural properties make it a very useful metal. This has led to its use in making various nickel alloys.
So, what are nickel alloys and inconel?
"Nickel alloy" is a general term that refers to grades of metals with particularly high nickel content. Inconel is just a special nickel alloy.
When you change the chemical composition of the alloy in question, its benefits also change. Different benefits mean different nickel alloys have different commercial uses.
Some of these uses include:
– Aircraft gas turbines
– Steam turbine power plant
– Medical applications
– Nuclear power system
– Chemical and petrochemical industry
Many of these applications require materials that are both corrosion-resistant and heat-resistant, so nickel and nickel alloys are well suited.
Of all nickel alloys, Specialty Pipe Materials specializes in two nickel alloys. Inconel alloy 625 has a nickel content of at least 58% and Inconel alloy 825 has a nickel content of 38-46%. Both products are known to perform well in corrosive environments.
Specialty Pipe Materials is able to source any type of product such as round bars, flanges, and even Inconel Alloy 625 and Inconel Alloy 825 seamless pipe.
Moving to Inconel
Inconel is a special group of austenitic nickel-chromium alloys known as "superalloys".
As mentioned before, one of the advantages of Inconel is its ability to be used in "extreme" environments. These "extremes" are either extreme temperatures or extreme pressures. This is because when Inconel is subjected to very high heat, it forms a very stable oxide layer that protects the metal surface from further corrosion. This process is called "passivation", and it's a very beneficial chemical reaction that effectively means that Inconel builds its own "barrier" to prevent future damage.
This passivation process also allows Inconel to maintain its strength over a wide temperature range. Other metals, such as aluminum, may not be able to withstand it.
Applications of Inconel
The significant advantages of Inconel mean that it can be used in a variety of different markets and industries, such as:
- Marines
- Aerospace
- core
– Chemical processing
- Petroleum and natural gas
- car
