When it comes to high temperature applications, material selection for the various components is critical. Inconel 600 and Inconel 718 are common superalloys used in many industries, including aerospace, oil and gas, and chemical processing. Both alloys have excellent mechanical properties and are well suited for high temperature and corrosive environments. In this article, we will explore the differences between Inconel 600 and Inconel 718 to help you decide which alloy to choose for your specific application.
Inconel 600 is a nickel-chromium alloy with good corrosion and oxidation resistance. The alloy also has good mechanical properties and can be formed into a variety of shapes. Inconel 600 is typically used in warm applications such as heat exchangers, furnaces and chemical processing equipment.
Inconel 718 is a nickel alloy with excellent corrosion and oxidation resistance. The alloy also has excellent mechanical properties and can be formed into a variety of shapes. Inconel 718 is commonly used in high temperature applications such as jet engines, gas turbines and chemical processing equipment.
Difference Between Inconel 600 and Inconel 718
Element:
Inconel 600, also known as Alloy 600, is a nickel-chromium alloy with good corrosion resistance. It contains about 76% nickel, 15% chromium and small amounts of iron, carbon and other elements. The alloy has excellent mechanical properties, high strength and good weldability, making it ideal for high temperature applications.
Inconel 718, on the other hand, is a nickel-based superalloy with a composition of approximately 52% nickel, 19% chromium, and small amounts of iron, niobium, and molybdenum. The alloy is known for its high-temperature strength, good corrosion resistance and excellent fatigue properties. Inconel 718 is a good choice for parts requiring high resistance to stress fracture and fatigue.
Temperature resistance:
Both Inconel 600 and Inconel 718 have excellent high temperature performance. Inconel 600 can withstand temperatures up to 1100°C (2000°F) and retains much of its strength at high temperatures. The alloy resists oxidation, carbonization and other forms of corrosion, making it ideal for use in furnace components, heat exchangers and chemical processing equipment.
Inconel 718, on the other hand, can operate continuously at temperatures up to 704°C (1300°F). The alloy can reach higher temperatures but may experience creep deformation and performance degradation when exposed to elevated temperatures for extended periods of time. Inconel 718 is ideal for jet engine components, heat exchangers and aerospace applications.
Corrosion resistance:
Both Inconel 600 and Inconel 718 have excellent corrosion resistance. Inconel 600 is resistant to oxidation, sulfidation and forms of high temperature corrosion. The alloy also provides good resistance to low temperature corrosion and stress corrosion cracking.
Inconel 718, on the other hand, is highly resistant to corrosion and oxidation in a variety of environments, including seawater, alkaline and acidic solutions. The alloy also protects against pitting, intergranular and crevice corrosion. Therefore, Inconel 718 is ideal for marine and chemical processing applications.
application:
Inconel 600 is used in a variety of industries including chemical processing, furnace components, heat exchangers and power generation. The alloy is also used in medical device, aerospace and nuclear industry applications.
Inconel 718, on the other hand, is widely used in the aerospace industry, where its high-temperature performance, fatigue resistance and high strength make it ideal for jet engine components, rotor and shaft assemblies, and combustion chambers. The alloy is also used in chemical processing, nuclear and marine industries, providing excellent corrosion resistance and strength.
difference in price:
Another difference between the Inconel 600 and Inconel 718 is their price. Generally speaking, Inconel 600 is cheaper than Inconel 718 due to its simpler ingredients. However, the cost of both alloys will vary depending on the specific grade and supplier.
in conclusion:
Inconel 600 and Inconel 718 are the most popular superalloys in high temperature and corrosion rings. While both materials offer excellent properties, their differences may make one alloy more suitable for a specific application. When selecting the right alloy for your application, you must understand its composition, temperature and corrosion resistance as well as the application in which you intend to use the alloy.
