What is Inconel718 ? Inconel718 is an nickel-based superalloy. IN718 has a unique alloy composition that gives it good comprehensive properties. This includes high strength, creep resistance, fatigue resistance, and excellent oxidation resistivity, especially at 650 degrees.

Many components of modern aero engines are made from IN718, including turbine discs.
In718 is also suitable for use in the nuclear reactor (heat exchanging pipe), sub (propellers blades, quick disengage device, auxiliary propel motor), chemical (vessels pumps valves pipe), power(industrial gas turbine), and the oil and natural gas industry (underground pipes, wellhead hardware torch arm).

Is Inconel Stronger Than Steel?
Every stainless steel is different. Different stainless steel varieties have different tensile strength, operating temperatures and resistance to certain corrosion agents. Grade 316 stainless is more resistant to chloride than 304 stainless, but also has a higher average price.

The tensile strengths of metals can be affected by certain handling and molding procedures. For example, Inconel 625 “rolled”, has a yield strength of 120-160ksi (827-1103MPa), while the “solution-treated”, has a yield strength of 103-135 ksi (714-896MPa).
Both tensile strengths classes are presented in ranges and not in specific numbers. This is because the strength can vary depending on the composition of the ingredients. Even small changes in iron, carbon or nickel content can greatly alter the strength.

Inconel625 has higher tensile strengths than class304 stainless steel, and is more able to keep this strength at higher temperatures.

Additionally, Inconel’s melting point is lower than that 304 stainless steel. However, it has a higher operating temp limit. Inconel is more stable than stainless steel at high temperatures. It is also less susceptible to oxidation, scaling, and other damage.

However, stainless is more resistant than Inconel to some chemicals such as sulfuric acids. It is up to the application that you choose which of these metal alloys.

Inconel alloys are more suitable for heat treatment and other high-temperature processes. The same goes for stainless steel alloys, which are often suitable for aseptic manufacturing and medical applications (or any other application that involves corrosion).
