2. Composition and performance.
Inconel625 is a nickel-based alloy composed mainly of elements such as nickel, chromium, molybdenum, and niobium. Among them, nickel provides excellent corrosion resistance and high-temperature stability, chromium enhances the oxidation and corrosion resistance of the alloy, molybdenum improves the strength and heat resistance of the alloy, and niobium further enhances the high-temperature strength and creep performance of the alloy.
Inconel625 has excellent mechanical properties, its tensile strength and yield strength are high, elongation is large, and it has good plasticity and toughness. In addition, Inconel625 also has good corrosion and oxidation resistance, and can work stably in high temperature and corrosive environments for a long time. Its maximum operating temperature can reach about 550 °C.
Third, the field of application.
Due to its excellent corrosion resistance, high temperature resistance and mechanical properties, Inconel625 is widely used in petroleum, chemical, aerospace and nuclear energy fields. In the petroleum and chemical industry, Inconel 625 is used in the manufacture of pipes, valves, reactors, heat exchangers and other equipment, which can withstand the erosion of various corrosive media such as acids and alkali salts. In the aerospace sector, Inconel625 is used in the manufacture of critical components such as engine components, combustion chambers, turbine discs, etc., which can withstand high temperatures and high intensity environments. In the field of nuclear energy, INCONEL625 is used to manufacture various components in nuclear reactors, such as fuel rod cladding, control rods, etc., with excellent corrosion resistance and high temperature performance.
Fourth, the processing method.
Inconel625 is processed in a similar way to other nickel-based alloys and can be used by cutting, welding, machining, and casting. Due to its high thermal conductivity and coefficient of linear expansion, corresponding technological measures need to be taken when welding to avoid the occurrence of thermal cracks. In terms of machining, due to the high hardness of Inconel 625, it is necessary to use carbide tools or diamond tools for machining. In addition, in order to obtain better mechanical properties, Inconel625 can be heat treated and solution treated.
