Inconel alloy, with its excellent high-temperature corrosion resistance and high-strength applications, has been widely used in various extreme environments. Most Inconel alloys are nickel-chromium alloys, where both nickel and chromium have good corrosion resistance at high temperatures, and chromium has excellent oxidation resistance. In this article, we will take a look at the different types of Inconel alloys one by one.
**Inconel 600**
Inconel 600 is a solid solution strengthened heat-resistant and corrosion-resistant alloy with good high-temperature corrosion properties, oxidation properties, hot and cold processing properties, low-temperature mechanical properties and hot and cold fatigue properties. It has high strength below 650°C, good formability, and is easy to weld. It is suitable for heat treatment and chemical processing industrial equipment.
**Inconel 601**
Inconel 601 has excellent oxidation properties at high temperatures, good carbonization resistance, good resistance to atmosphere with oxidizing sulfur content, good mechanical properties at room temperature and high temperature, and has good properties due to the control of carbon content and grain size. stress corrosion cracking resistance. Inconel 601 exhibits high creep rupture strength and is suitable for applications at temperatures above 500°C.
**Inconel 601GC**
Inconel 601GC is the 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 properties such as oxidation and carbonization.
**Inconel 625**
Inconel 625 has good corrosion and oxidation properties, good tensile properties and fatigue properties from low temperature to 980°C, as well as stress corrosion properties in salt spray atmosphere.
**Inconel 686**
Inconel 686 is a low carbon nickel-chromium-molybdenum-tungsten alloy with significant resistance to general corrosion, stress corrosion cracking, pitting and crevice corrosion, oxidation, reducing and mixed acids. It also exhibits significant corrosion properties in environments containing halides. In addition, Inconel 686 is resistant to seawater and other marine environments and is widely used in chemical production, marine, air pollution control (flue gas desulfurization) industries, pulp and paper industries, and waste management.
**Inconel 690**
Inconel 690 has resistance to chloride corrosion, high temperature and high pressure water stress corrosion, strong oxidizing media and HNO2-HF mixed corrosion. This alloy is commonly used in nuclear waste treatment plants, steam generators and nitric acid-resistant components.
**Inconel 718**
Inconel 718 is a precipitation hardened Ni-Cr-Fe alloy with added niobium and molybdenum. High strength and good toughness below 650°C. Inconel 718 exhibits corrosive properties in both low and high temperature environments. Delivery status can be solution treated or precipitation hardened.
**Inconel 725**
Inconel 725 is a nickel-chromium-molybdenum-niobium alloy with excellent corrosion and stress corrosion properties. Aging heat treatment can greatly improve the strength, ductility and tensile strength of the alloy.
**Inconel 740H**
Inconel 740H is age hardened by precipitating the gamma major and minor phases. After age strengthening, 740H alloy exhibits excellent high-temperature strength below 850°C. The high content of chromium and cobalt gives 740H alloy excellent high-temperature oxidation, carbonization and sulfurization properties.
**Inconel X-750**
Inconel X-750 exhibits good corrosion and oxidation properties, as well as good strength up to 980°C. In addition, Inconel X-750 also has good low-temperature properties and formability, and is mainly used in aviation and industrial gas turbine components.
**Inconel 751**
Inconel 751 is a precipitation hardening superalloy similar to Alloy 750. It has good wear resistance, strength and corrosion properties as well as hot hardness at high temperatures and is mainly used for exhaust valves of internal combustion engines.
**Inconel 783**
Inconel 783 is an oxidation-resistant superalloy with a low coefficient of thermal expansion specifically developed for turbine applications. By adding niobium and aluminum, the strength of 783 alloy can be enhanced through a precipitation hardening heat treatment. In addition, the aluminum contained in it gives it excellent oxidation properties at high temperatures. The density of Alloy 783 is approximately 5% less than Super Alloy 718.
In summary, Inconel alloy has been widely used in various extreme environments due to its excellent high temperature corrosion resistance and high strength applications.
