Nickel Inconel 718 Materials

Inconel 718is a precipitation-hardening nickel-chromium alloy containing significant amounts of iron, columbium, and molybdenum, along with lesser amounts of aluminum and titanium. 718 materials maintain high strength and good ductility up to 1300°F (704°C). This alloy has relatively good weldability, formability, and excellent cryogenic properties compared to other precipitation hardening nickel alloys. The sluggish precipitation hardening response of this alloy allows it to be readily welded without hardening or cracking. Inconel Alloy 718 is non-magnetic. It maintains good corrosion resistance and oxidation resistance and is used for parts requiring high resistance to creep and stress rupture up to 1300°F (704°C) and oxidation resistance up to 1800°F (982°C). Nickel alloys such as Inconel 718 are well-suited to high-temperature applications as most other metals are either brittle or oxidize when exposed to elevated temperatures. However, nickel-based alloys will quickly form a protective oxide layer when heated in an atmosphere containing oxygen, thereby preventing further oxidation. It also has a relatively high melting point.


ASME SB 637 Inconel 718 Bars

Inconel 718 round bar is a “superalloy” for a reason – it maintains great strength even close to its 1,300°F melting point. Its nickel, chromium, and niobium composition gives 718 stability despite scorching temperatures hot enough to melt aluminium many times over. It takes a lot to wear down parts made from this high-performance material. Inconel 718 round bar with a lot of features and different variation in different sizes and shapes which are discussed, Alloy 718 Rod is a high strength, corrosion resistant nickel chromium physical used at 423 to 1300 F. The age hard allow alloy can be willingly fabricated, even into multifaceted parts. Its welding features, especially its resistance to post weld fast are outstanding.


Inconel 718 Hex Bar are fundamentally used as a Connector between the bars at the middle. They are also used as a wad in to resist pressure in Pressure Regulators. These have enormous demand in many large scale manufacturing purposes. Our Inconel 718 Hex Bar are one of the successful known for its durable escape proof property. We are famous for Inconel 718 Alloy Bar which is also one of the bestselling known for its durable leak-proof property.


Chromium, niobium, molybdenum and trace elements like aluminium and titanium are carefully balanced to enhance properties. This UNS N07718 Half Round Bar composition forms a nickel matrix full of strengthening precipitate particles, giving 718 its muscular but flexible properties. It works great under fire – resisting wear, fatigue cracks, oxidation decay and the effects of ageing remarkably well compared to alternatives. Machining does require rigid setups and gradual cuts with specialized tools due to Inconel 718 tendency to work hardened fast. But with deliberate care and maintenance, components with fine dimensional tolerance and smooth surface finish work for a long time. Despite its higher cost, the material has exceptional performance, making it the first for critical duty hardware despite higher cost.

Characteristics of Inconel 718

Tensile Strength and Temperature Resistance

Inconel 718 bar is known for its exceptional tensile strength which makes it stand out across different temperature ranges. Precisely speaking, this nickel-based superalloy has a tensile strength value of about 1241 MPa. Moreover, it can sustain its mechanical integrity up to very high temperatures (700°C/1292°F) over long time spans. For these reasons, Inconel 718 works best for stressful conditions associated with heat such as those found in aerospace industry, power generation plant or oil refineries due to their demanding performance standards.


Chemical Properties and Corrosion Resistance

Because of the complex chemical makeup of Inconel 718 Round Steel including such compositions as nickel, chromium, and molybdenum which are the primary elements, it has special properties which make it resistant to corrosion. Therefore, these features help enhance resistance against many forms of oxidation and deterioration. For example, this material has high levels of chromium that produce a strong passive film which prevents oxidation while nickel ensures its resistance to both acidic and alkaline conditions. Moreover, its ability to endure pitting and crevice corrosion even in highly chloridized atmospheres shows why it can be used in harsh environments. This uncommon ability to withstand any form of chemical degradation makes Inconel 718 Round Steel a perfect choice for corrosive industries like marine engineering, chemical processing or aerospace where corrosion is always an issue.


What are the Applications of Inconel 718?

With its strong properties and characteristics, UNS N07718 bar is used in various applications. It is used to make parts that can come in various shapes and is suitable for use in making aeronautic and automobile parts, jet engines, marine turbines, fuel lines, etc.

Other applications include the following:

3D printing
