Recently, the Russian President hosted a meeting with oil and gas industry representatives. He said that the refusal of some Western countries to cooperate normally with Russia and deny some Russian energy resources has hit millions of European people deeply and caused an energy crisis. These "unfriendly countries" are experiencing severe inflation, and Russia is also facing the three major challenges of increasing domestic consumption of energy In718 powder are still very uncertain.
What is Inconel 718?
Inconel 718 is a nickel-based superalloy. The unique alloy composition design of IN718 makes it have good comprehensive properties, namely high strength, creep resistance and fatigue life, good ductility, excellent oxidation resistance, especially under 650℃ temperature, its mechanical properties have good stability.
Many parts of modern aero engines, such as turbine discs, blades, brakes, shafts, stators, seals, supports, pipes, fasteners, etc., are made of IN718.
In718 can also be used in nuclear reactor (heat exchanger pipe), sub (propeller blades, quick disconnect device, auxiliary propulsion motor), chemical (vessels, pumps, valves, pipe), power (industrial gas turbine), the oil and gas industry (underground pipelines, wellhead hardware, torch arm).
Is Inconel Stronger Than Steel?
Each stainless steel has a different formulation. Stainless steel variants have distinct tensile strengths, recommended operating temperatures, and resistance to specific corrosion agents. For example, grade 316 stainless steel tends to have higher chloride resistance (but also higher average cost) than 304 stainless steel.
In addition, certain handling and molding methods may affect the tensile strength of the metal. For example, the Inconel 625 "rolled" bar has a tensile strength of 120-160 ksi (827-1103 MPa), while the "solution treated" bar has a tensile strength of 103-130 ksi (714-896 MPa).
Both tensile strength classes are given in ranges rather than specific numbers. That's because the strength of the metal can vary, depending on the exact proportion of ingredients in it -- small changes in carbon, nickel or iron content can significantly alter the strength of the final product.
Inconel625 has a higher tensile strength than class 304 stainless steel and is better able to maintain this strength at higher operating temperatures.
In addition, although the melting point of this particular type of Inconel is lower than that of 304 stainless steel, it has a higher operating temperature limit. This is because Inconel is stronger than stainless steel at high temperatures and is also more resistant to oxidation and scaling.
However, stainless steel may be better at resisting certain chemicals than Inconel such as sulfuric acid. Therefore, the choice of which of the two metal alloys to use will depend on the specific application in which they will be used.
Inconel alloys tend to be better suited for heat treatment applications and other high-temperature processes. At the same time, stainless steel alloys are usually suitable for aseptic manufacturing or medical applications (or any application involving corrosion).
