Inconel alloys are Inconel alloys with some iron in them. Inconel alloy contains more nickel than stainless steel, so its corrosion resistance to hot caustic soda solution and alkali sulfate is better than that of stainless steel plate, and its high temperature corrosion resistance is also stronger.
(1) Inconel600 is a NiCrFe solid solution strengthened alloy with excellent high temperature resistance, oxidation resistance, high-quality hot-cold processing and electric welding performance, and good thermal strength and plastic deformation below 700 ℃. Because the alloy contains Cr, it has better corrosion resistance than Ni in reducing natural environment, and also has excellent corrosion resistance in oxidizing natural environment because of high Ni content. inconel600 has very good corrosion resistance to high-temperature hydrochloric acid, phosphoric acid, glacial acetic acid, oleic acid and other citric acids at room temperature with various concentrations, and is resistant to dry chlorine and hydrogen chloride. Azimuth etch performance. Inconel600 cannot be used for high-temperature hydrochloric acid and high-temperature sulfuric acid with high concentration, which can cause intergranular corrosion in high-temperature strong acid aqueous solution. Therefore, the product workpiece should be as free of ground stress as possible.
(2) Inconel625 is a low-carbon and environmentally friendly Ni, Cr, Mo, Nb alloy, which has high-quality corrosion resistance to various corrosive substances. After the anti-aging solution, even if the temperature is kept at 650℃～400℃ for 50 hours, it is still not easy to have sensitization tendency. Common in oxidizing acids, pitting resistance, ductile fracture. It has excellent corrosion resistance in fluoride and sea surface. In the natural environment of acid gas, flue gas denitrification, paper industry and other applications are widely used.
(3) InconelX-750 is an aging-enhanced nickel-based superalloy, which has excellent corrosion resistance and stress relaxation elongation at break at high temperature, and has excellent high-strength corrosion resistance and oxidation resistance at 980 ℃. Compressive strength. It has good relaxation resistance at 540 ℃, and also has excellent formability and electric welding performance. It has excellent structural mechanical properties in the ultra-low temperature natural environment. Commonly used in the production of springs working at high temperatures, large and medium-sized high-pressure containers, torsion chambers on rocket engines, and reverse thrust equipment for aircraft.
(4) Inconel718 is a nickel-based alloy used for high temperature precipitation hardening. Excellent comprehensive performance in the range of -253℃～700℃, high compressive strength, fatigue limit, stress relaxation compressive strength and elongation at break at 700℃, excellent oxidation resistance at 1000℃, It has stable organic chemical properties at ultra-low temperature. Commonly used in steam turbine generators, solid fuel rockets, ultra-low temperature engineering projects, acid-base environmental protection projects.
(5) Incoloy800 is a full martensitic Ni, Fe, Cr alloy that is anti-aging solution for titanium. It has excellent resistance to intergranular corrosion cracking, crevice corrosion resistance, ductile fracture resistance, very good oxidation resistance and non-reducing thermal acid resistance, and has very good corrosion resistance in various substances, such as : Hydrochloric acid, phosphoric acid, sodium cyanide, citric acid, sodium hydroxide solution, ferric chloride solution and their mixed acids. Commonly used in various industrial production industries where the application temperature does not exceed 550 °C; deep sea pipeline system software; hydrochloric acid, phosphoric acid industrial production, crude oil refining, food industry, chemical industry and as high pressure CO2 flame retardant alloy.
