Feature
Due to its exceptional strength and resistance to extreme temperatures, Inconel 718 is an ideal choice for complex components that must retain their integrity in demanding conditions. Some of the many advantages of using the alloy 718 Inconel include the following:
Very Versatile
With its unique combination of properties, Inconel 718 is a great choice for numerous applications, from petrochemical to aerospace. It has good weldability and high resistance to oxidation and stress corrosion cracking.
High Mechanical Strength
Inconel 718 is stronger than other alloys, allowing it to be used in high-temperature environments as well as under pressure. It features an age-hardened tensile strength of 185- 220 ksi, which is roughly twice as strong as its sister alloy, Inconel 625.
Stable in Extreme Environments
From cryogenic temperatures to 1400°F, Inconel 718 remains stable, demonstrating exceptional tensile and impact strength even when exposed to harsh conditions. It also has very low thermal expansion and is resistant to oxidation and corrosion, making it a great option for industries like aerospace, power plants, oil and gas, and more.
Resistant to Corrosion and Thermal Shock
Inconel 718 has beneficial protection to atmospheric decay and corrosion at climates within the nickel alloys strength space. It has somewhat-favorable weldability, formability, and exceptional low temperature properties comparable to other PH nickel alloys.
NACE MR0175 Resistance
In the NACE MR0175 form, Inconel 718 has a required minimum yield strength of 120 KSI. It is processed differently than the AMS conditions to enhance its corrosion resistance in downhole tools and completion components.
AMS5663 Resistance
AMS 5663 has a minimum yield strength of 150 KSI which makes it suitable for applications that require intense strength in both the aerospace and oil & gas industries.

Application
Inconel 718 is an incredibly versatile superalloy and is used in a variety of industries that require strength, temperature resistance, and corrosion resistance. This alloy is often used for components such as valves and connectors that are exposed to high-pressure fluids or gasses in industries such as the following:

Aerospace
Inconel 718 has been used in many applications within the aerospace industry due to its light weight, high-temperature resistance and excellent corrosion resistance. It is often used for aircraft engine parts such as turbine blades, exhaust systems and manifolds as well as other engine components like Inconel 718 bolts, valve bodies, and nuts.

Oil and Gas
Because of its high tensile strength and corrosion resistance, Inconel 718 is an ideal material for oil and gas applications. It is often used in downhole tools, valves and flanges as well as other components exposed to extreme temperatures or corrosive environments.

Chemical and Petrochemical Plants
In chemical and petrochemical plants, Inconel 718 is often used in valves, pumps, and other components that require high strength at elevated temperatures. It also offers good corrosion resistance to many chemicals, acids and solvents making it an ideal choice for these applications.

Power Plants
Inconel 718 is often used in power plants due to its high strength and corrosion resistance. It is often chosen for components that are exposed to high temperatures such as turbine blades, bearings, valve bodies, nuts, and bolts.
