Inconel:
Inconel 600
Inconel 600 is a solid solution strengthened heat-resistant and corrosion-resistant alloy with good high temperature corrosion resistance, oxidation resistance, hot and cold processing properties, low temperature mechanical properties, cold and hot fatigue properties. It features high strength under 650 ° C, good formability and easy soldering, suitable for heat treatment and chemical processing industrial equipment.
Inconel 601
Inconel 601 features excellent oxidation resistance at high temperature, good resistance to carbonization, good resistance to oxidized sulfur-containing atmosphere, good mechanical properties at room temperature and high temperature, good stress corrosion crack resistance due to controlled carbon content and grain size. Inconel 601 exhibits high creep rupture strength, suitable for applications with temperature above 500 °C.
Inconel 601GC
Inconel 601GC is a grain-controlled version of Inconel 601.
Inconel 617
Inconel 617 is a nickel-chromium-cobalt-molybdenum alloy with excellent mechanical properties at high temperatures. This alloy also exhibits high-temperature corrosion resistance such as oxidation and carbonization.
Inconel 686
Inconel 686 is a low carbon nickel-chromium-molybdenum-tungsten alloy with remarkable resistance to general corrosion, stress corrosion cracking, pitting and crevice corrosion, oxidization, reducing and mixed acids. It also exhibits pronounced corrosion resistance in environments containing halides. Besides, Inconel 686 is resistant to sea water and other marine environments, widely used in chemical production, marine, air pollution control (flue gas desulfurization) industry, pulp and paper industry and waste management.
Inconel 690
Inconel 690 is resistance to chloride corrosion, high temperature and high-pressure water stress corrosion, strong oxidizing medium and HNO2-HF mixed corrosion. This alloy is commonly used in nuclear waste treatment plants, steam generators, and nitric acid resistant parts.
Inconel 625
Inconel 625 features good corrosion and oxidation resistance, good tensile and fatigue properties from low temperature to 980 ° C, as well as stress corrosion resistance in salt atmosphere.
Inconel 718
Inconel 718 is a precipitation-hardening Ni-Cr-Fe alloy with addition of the niobium and molybdenum. It features high strength and good toughness under temperatures below 650 °C. Inconel 718 exhibits corrosion resistance in both low and high temperature environments. Delivery state can be solution treatment or precipitation hardening.
Inconel 725
Inconel 725 is a type of Nickel-chromium-molybdenum-niobium alloy with excellent corrosion resistance and stress corrosion resistance. Aging heat treatment can greatly improve the alloy strength, ductility and tensile strength.
Inconel 740
Inconel 740 obtains age hardening by precipitation of the gamma primary and secondary phases. After aging strengthening, the 740 alloy exhibits excellent high temperature strength under temperatures below 850 °C. High content of chromium and cobalt contained within gives the 740 alloy excellent oxidation resistance, carbonization and vulcanization at high temperatures.
Inconel 751
Inconel 751 is a type of precipitation hardening super alloy similar to alloy 750. It features good wear resistance, strength and corrosion resistance as well as hot hardness under high temperatures, mainly used for exhaust valves on internal combustion engines.
Inconel 783
Inconel 783 is an oxidation-resistant super alloy with a low coefficient of thermal expansion, developed specifically for turbine applications. With the addition of niobium and aluminum, the strength of the 783 alloy can be enhanced by precipitation hardening heat treatment. In addition, the aluminum contained within gives it excellent oxidation resistance under high temperatures. The density of 783 alloy is smaller than that of super alloy 718 by roughly 5%.
Inconel X-750
Inconel X-750 exhibits good corrosion resistance and oxidation resistance, as well as good strength below 980 °C. In addition, Inconel X-750 also has good low temperature performance and molding performance, mainly used as aerospace and industrial gas turbine components.
