Introduction:
Inconel 702 is a high-strength nickel-based alloy that offers excellent resistance to heat and corrosion. 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 702 plates, pipes, round bars, and strips. This article will provide a detailed analysis of Inconel 702, covering its chemical composition, mechanical properties, applications, standards, and comparison with other high-temperature alloys.
Chemical Composition:
The chemical composition of Inconel 702 consists of nickel (55.0% min), chromium (17.0-21.0%), iron (5.0%), 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 702 with its superior properties such as high-temperature strength, corrosion resistance, and excellent ductility.
Mechanical Properties:
Inconel 702 exhibits excellent mechanical properties, making it ideal for use in high-temperature applications. Its tensile strength ranges from 930 MPa to 1035 MPa, and its yield strength ranges from 760 MPa to 895 MPa. The alloy also has good toughness and ductility, making it easy to work with and form into various shapes and sizes. Additionally, Inconel 702 has high fatigue strength and resistance to cracking and fracture, even when subjected to repeated thermal cycling.
Applications:
Inconel 702 finds application in various industries, including aerospace, nuclear power, and chemical processing. In the aerospace industry, Inconel 702 is used for turbine blades, exhaust systems, and other components that require high-temperature strength and resistance to corrosion. 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 chemical processing industry, Inconel 702 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.
Standards:
Inconel 702 meets various international standards such as ASTM B163 (pipe), ASTM B166 (round bar), and ASME SB-166 (round bar). These standards ensure that Inconel 702 products meet specific requirements regarding chemical composition, mechanical properties, and performance in high-temperature applications.
Comparison:
Inconel 702 is often compared with other high-temperature alloys such as Inconel 718, Inconel X750, and Hastelloy C276. Compared to Inconel 718, Inconel 702 offers better overall corrosion resistance and improved resistance to carburization. When compared to Inconel X750, Inconel 702 exhibits superior resistance to high-temperature oxidation and sulfidation. In comparison to Hastelloy C276, Inconel 702 has better resistance to carburization and phosphoric acid. Each alloy has its unique properties and applications, and the choice of alloy depends on specific requirements and operating conditions.
