How hard is 718 Inconel?
Inconel 718 is a high-strength nickel alloy with precipitation hardening capabilities, which helps it maintain its resistance, strength, oxidation and ductility in the most extreme environments.
Such properties must remain constant at high temperatures for long periods of time, and the Inconel range can meet this requirement. Inconel 718 bar stock is used in many industries, including aerospace, oil and gas, chemical and critical application valves.

Advantages of Inconel 718
Due to its outstanding strength and resistance to extreme temperatures, Inconel 718 is ideal for complex components that must maintain integrity under demanding conditions. The many advantages of using 718 Inconel alloy include:
Versatile
Inconel 718 has a unique combination of properties that make it ideal for a wide range of applications, from petrochemicals to aerospace. It has good weldability and is highly resistant to oxidation and stress corrosion cracking.
High Mechanical Strength
Inconel 718 is stronger than other alloys and can be used in high temperature environments and under pressure. Its age-hardened tensile strength is 185-220 ksi, about twice that of its sister alloy, Inconel 625.
Stable in Extreme Environments
Inconel 718 is stable from cryogenic temperatures to 1400°F, exhibiting superior tensile and impact strength even in adverse conditions. It also has very low thermal expansion and is resistant to oxidation and corrosion, making it ideal for industries such as aerospace, power plants, and oil and gas.
Resistant to Corrosion and Thermal Shock
Inconel 718 has good resistance to atmospheric corrosion and atmospheric corrosion in climates within the strength range of nickel alloys. Compared to other PH nickel alloys, it has good weldability, formability, and excellent cryogenic properties.
NACE MR0175 Resistance
In the NACE MR0175 form, Inconel 718 has a minimum yield strength requirement of 120 KSI. It is processed differently from the AMS condition 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 requiring high strength in the aerospace and oil and gas industries.
