Introduction:
Inconel 722 is a high-temperature nickel-based alloy that offers excellent corrosion resistance, strength, and thermal stability even in harsh environments. It contains nickel, chromium, iron, and other elements that provide it with unique properties such as high-temperature strength, good weldability, and outstanding resistance to oxidation and carburization. ANTON METAL is a leading supplier of Inconel 722 plates, pipes, round bars, and strips. This article will provide a detailed analysis of Inconel 722, covering its chemical composition, mechanical properties, applications, standards, and comparison with other high-temperature alloys.
Chemical Composition:
The chemical composition of Inconel 722 consists of nickel (50.0% min), chromium (19.0-22.5%), iron (17.0-20.0%), molybdenum (2.75-3.25%), titanium (1.0-1.6%), aluminum (0.6-1.2%), and other trace elements such as manganese, silicon, and carbon. This unique combination of elements provides Inconel 722 with its superior properties such as high-temperature strength, corrosion resistance, and excellent ductility.
Mechanical Properties:
Inconel 722 exhibits excellent mechanical properties, making it ideal for use in high-temperature applications. Its tensile strength ranges from 1050 MPa to 1200 MPa, and its yield strength ranges from 760 MPa to 900 MPa. The alloy also has good toughness and ductility, making it easy to work with and form into various shapes and sizes. Additionally, Inconel 722 has high fatigue strength and resistance to cracking and fracture, even when subjected to repeated thermal cycling.
Applications:
Inconel 722 finds application in various industries, including the oil and gas industry, chemical processing, and power generation. In the oil and gas industry, Inconel 722 is used for downhole tools, such as drill collars, subs, and turbine blades. In the chemical processing industry, the alloy is utilized for reactor vessels, heat exchangers, and piping systems that handle corrosive chemicals such as sulfuric acid, hydrochloric acid, and nitric acid at high temperatures. In the power generation industry, Inconel 722 is used for components in steam turbines, gas turbines, and nuclear reactors that operate at high temperatures.
Standards:
Inconel 722 meets various international standards such as ASTM B637 (bar), ASTM B670 (plate), and ASME SB-564 (forgings). These standards ensure that Inconel 722 products meet specific requirements regarding chemical composition, mechanical properties, and performance in high-temperature applications.
Comparison:
Inconel 722 is often compared with other high-temperature alloys such as Inconel 718, Inconel 625, and Hastelloy C-276. Compared to Inconel 718, Inconel 722 offers superior corrosion resistance and improved resistance to carburization. When compared to Inconel 625, Inconel 722 exhibits better overall strength and resistance to stress corrosion cracking. In comparison to Hastelloy C-276, Inconel 722 has better resistance to high-temperature oxidation and carburization. Each alloy has its unique properties and applications, and the choice of alloy depends on specific requirements and operating conditions.
