IN718: The Most Widely Used Superalloy Material in the Field of Additive Manufacturing
As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.
For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.
Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the IN718 powder in the chemical industry will also
be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. West Texas Intermediate for April settled 7% higher at $112.12 a barrel on Monday.
Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the product name.
High temperature alloy refers to a type of metal material based on iron,
nickel, and cobalt that can work for a long time at a high temperature above 600
℃ and a certain stress; and has high high temperature strength, good oxidation
and corrosion resistance, Good fatigue performance, fracture toughness and other
comprehensive properties. The superalloy is a single austenitic structure, which
has good structure stability and service reliability at various
Based on the above-mentioned performance characteristics, and the high degree
of alloying of superalloys, it is also called "superalloys". It is an important
material widely used in aviation, aerospace, petroleum, chemical industry, and
ships. According to the matrix elements, high-temperature alloys are divided
into iron-based, nickel-based, cobalt-based and other high-temperature alloys.
The service temperature of iron-based superalloys can generally only reach
750~780℃. For heat-resistant parts used at higher temperatures, nickel-based and
refractory metal-based alloys are used. Nickel-based superalloy occupies a
particularly important position in the entire field of superalloys. It is widely
used to manufacture the hottest parts of aviation jet engines and various
industrial gas turbines.
Features and application fields of IN718
The unique alloy composition design of IN718 makes it have good comprehensive
properties, namely higher strength, creep resistance and fatigue life, good
ductility, excellent oxidation resistance, especially under 650℃, its mechanical
properties Has good stability. Many parts of modern aero-engines, such as
turbine discs, blades, brakes, shafts, stators, seals, supports, pipes,
fasteners, etc., are all made of IN718.
At the same time, IN718 is also used in nuclear reactors (heat exchanger
pipelines), submarines (propeller blades, quick disconnect devices, auxiliary
propulsion motors), chemical industry (containers, pumps, valves, pipelines),
power generation (industrial gas turbines), oil and gas industry ( Downhole
piping, wellhead hardware, flare arm) and other fields have important
Application of IN718 in the field of additive manufacturing
When traditional manufacturing methods such as machining, forging or welding
are used, annealing is often required before the process starts, and the high
temperature corrosion and creep resistance of the parts will be affected. The
results of additive manufacturing of IN718 alloy show that the mechanical
properties have not been sacrificed and can even exceed the performance of cast
or forged parts. In addition, IN718 is a typical difficult-to-machine material
due to its high cutting temperature and serious work hardening. For the complex
geometries usually required in aerospace applications, the manufacture of IN718
parts is often very difficult and costly.

Prior to the impact of COVID-19 on the chemicals and materials industry and the price of the IN718 powder, many industry observers expected low to flat growth in 2021 in all regions outside Asia, with many countries seeing slower growth compared to recent years. Operational excellence has long been a hallmark of the chemical industry, and many companies are financially able to withstand short-term dips in end-market demand due to rapid leverage from reduced capex on hand.
The analysis shows that, whatever the final course of the pandemic, we can expect the inevitable long-term effects. Workplaces are expected to slowly return to pre-COVID-19 practices. Companies investing in enterprise-wide digital initiatives saw these "payoffs" in the early pandemic environment.
