This article will provide a detailed analysis of Inconel 690, covering its chemical composition, mechanical properties, applications, standards, and comparison with other high-temperature alloys.
Chemical Composition:
The chemical composition of Inconel 690 consists of nickel (58.0% min), chromium (27.0-31.0%), iron (7.0-11.0%), manganese (1.0%), silicon (0.5%), carbon (0.05%), sulfur (0.015%), and other trace elements such as titanium, aluminum, and copper. This unique combination of elements provides Inconel 690 with its superior properties such as high-temperature strength, corrosion resistance, and excellent ductility.
Mechanical Properties:
Inconel 690 exhibits excellent mechanical properties, making it ideal for use in high-temperature applications. Its tensile strength ranges from 750 MPa to 850 MPa, and its yield strength ranges from 310 MPa to 415 MPa. The alloy also has good toughness and ductility, making it easy to work with and form into various shapes and sizes. Additionally, Inconel 690 has high fatigue strength and resistance to cracking and fracture, even when subjected to repeated thermal cycling.
Applications:
Inconel 690 finds application in various industries, including chemical processing, nuclear power, and aerospace. In the chemical processing industry, Inconel 690 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 nuclear power industry, the alloy is used for components in reactors that operate at high temperatures and are exposed to radiation. In the aerospace industry, Inconel 690 is used for turbine blades, exhaust systems, and other components that require high-temperature strength and resistance to corrosion.
Standards:
Inconel 690 meets various international standards such as ASTM B168 (plate), ASTM B163 (pipe), and ASME SB-166 (round bar). These standards ensure that Inconel 690 products meet specific requirements regarding chemical composition, mechanical properties, and performance in high-temperature applications.
Comparison:
Inconel 690 is often compared with other high-temperature alloys such as Inconel 600, Inconel 625, and Hastelloy C276. Compared to Inconel 600, Inconel 690 offers better overall corrosion resistance and improved resistance to stress corrosion cracking. When compared to Inconel 625, Inconel 690 exhibits superior resistance to sulfidation and carburization. In comparison to Hastelloy C276, Inconel 690 has better resistance to high-temperature oxidation. Each alloy has its unique properties and applications, and the choice of alloy depends on specific requirements and operating conditions.
