What is the difference between Inconel 718 and 316l?
Inconel 718 is a high strength nickel alloy with the capability to be precipitation hardened, which helps keep its resistance, strength, oxidation, and ductility while in the most extreme environments.
This performance must be kept constant during long periods at high temperatures, which is fulfilled by the Inconel series. Inconel 718 bar stock is used in many industries including aerospace, oil and gas, chemical, and valves for critical applications.

Benefits of Inconel 718
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.
Inconel 718 Composition
Inconel 718 is an age-hardenable nickel alloy with high strength and corrosion resistance.
Properties of Inconel 718
Inconel 718 has several properties that make it an ideal choice for many applications, such as its high tensile strength, excellent oxidation and corrosion resistance, good weldability, and low thermal expansion. It also has a range of mechanical properties that depend on the heat treatment used to produce it.
Inconel 718 vs Stainless Steel 316
The biggest differences between 718 Inconel and 316 stainless steel is in corrosion resistance and strength at high temperatures; in both of these areas, Inconel 718 will outperform the stainless steel 316 alloy. Inconel alloys also resist oxidation and scaling.
