GH4169 alloy is a nickel-based superalloy strengthened by the precipitation of body-centered tetragonal γ" and face-centered cubic γ′ phases. It exhibits excellent comprehensive performance in the temperature range of -253 to 700°C, with the highest yield strength among deformed high-temperature alloys below 650°C. It also has good fatigue resistance, radiation resistance, oxidation resistance, and corrosion resistance, as well as good machinability, weldability, and long-term microstructural stability. This allows for the manufacturing of complex-shaped components, leading to extensive applications in aerospace, nuclear energy, and the petroleum industry within the specified temperature range.

Widely used in the chemical and petrochemical fields, such as in components and catalytic systems that come into contact with chlorinated organic substances. This material is particularly suitable for use in high-temperature environments, mixed with impurities in inorganic acids and organic acids (such as formic acid and acetic acid), and in seawater corrosion environments. Other application areas include: pulp and paper industry, such as cooking and bleaching vessels; washing towers, reheaters, and wet gas fans in FGD systems; equipment and components operating in acidic gas environments; reactors for acetic acid and acidic products; sulfuric acid condensers; methylene diphenyl diisocyanate (MDI); production and processing of impure phosphoric acid.

Hastelloy B3 (N10675) nickel-based alloy material is an improved new material based on Hastelloy B2, enhancing the thermal stability of the material, thereby improving its corrosion resistance, while also improving hot and cold forming properties. In recent years, it has been increasingly used in the production and manufacturing of chemical equipment.

Monel 400 (N04400) is a widely used and versatile corrosion-resistant alloy with excellent overall performance. This alloy exhibits outstanding corrosion resistance in hydrofluoric acid and fluorine gas environments, as well as good resistance to hot concentrated alkaline solutions. It also resists corrosion from neutral solutions, water, seawater, atmosphere, and organic compounds. An important characteristic of this alloy is that it generally does not develop stress corrosion cracks and has good machinability.

Inconel X-750 alloy is primarily a nickel-based high-temperature alloy that is strengthened by aging with the γ′ [Ni3(Al, Ti, Nb)] phase. It exhibits good corrosion resistance and oxidation resistance below 980°C, high strength below 800°C, and good relaxation resistance below 540°C. Additionally, it has excellent forming and welding properties. This alloy is mainly used to manufacture annular parts, structural components, and bolts that operate below 800°C and require high strength and corrosion resistance, as well as flat springs and helical springs that operate below 540°C with moderate or lower stress and require relaxation resistance. It can also be used to manufacture parts such as gas turbine blades. Available forms include plates, strips, bars, forgings, rings, wires, and tubes.

GH3128 is a nickel-based alloy with tungsten and molybdenum solution strengthened and boron, cerium and zirconium strengthened at grain boundaries, which has high plasticity, high durable creep strength, good oxidation resistance and stamping, welding and other properties. Its comprehensive performance is better than that of similar nickel-based solid solution alloys such as GH3044 and GH3536. It is suitable for manufacturing combustion chamber flame cylinders, afterburner shells, adjusting sheets and other high-temperature parts and components of aero engines working for a long time at 950°C, the main products are cold-rolled sheets, and hot-rolled plates, bars, forgings, wires and pipes can also be supplied.

GH80A is a nickel-chromium matrix, adding aluminum, titanium to form a γ′ phase diffusion strengthened superalloy, except for the aluminum content is slightly higher, the other is similar to GH4033, the use temperature is 700~800 °C, at 650~850 °C has good creep resistance and oxidation resistance. The alloy has good cold and hot working performance, and is mainly supplied with hot-rolled bars, cold-drawn bars, hot-rolled plates, cold-rolled plates, strips and ring parts, etc., which are used to manufacture engine rotor blades, guide vane bearings, bolts, blade lock plates and other parts.

Inconel 617 alloy performs particularly well at high temperatures. At ambient temperatures up to 1100°C, it is not only able to withstand long-term oxidation and carbonization corrosion, but also exhibits excellent corrosion resistance in vulcanized environments. The alloy's ability to resist corrosion stems from its unique chemical composition and microstructure, which allow it to maintain stable performance in high-temperature and corrosive environments.

The thermal processing characteristics of Inconel 230 are similar to those of Inconel 617 and 625. The alloy can be in the temperature range of 1010~1230°C Large deformation is processed within the perimeter, and small deformation can be processed at 954°C. Although it is easy to align by conventional processes Gold is cold-worked, however, the alloy has a high work hardening rate. To achieve the effect, it should be combined under fine-grained conditions Gold is cold-worked, and multiple intermediate annealing should be used.

Inconel 690 alloy has excellent resistance to intergranular corrosion and intergranular stress corrosion cracking, and is mainly used as a heat transfer tube material for steam generators in pressurized water reactor nuclear power plants. Materials for heat transfer tubes for steam generators in PWR nuclear power plants have gone through a history of development, including 304 austenitic stainless steel, Inconel 600 alloy, 800 alloy and Inconel 690 alloy. Corrosion failure studies in service with Inconel 600 alloys have shown that intergranular corrosion and intergranular stress corrosion cracking are major problems. Inconel 690 alloy is used as a heat transfer tube material for steam generators in pressurized water reactor nuclear power plants, and there have been no reports of breakage since it was put into use in the 90s of the last century.
