Inconel is in the superalloy family. It is nickel-chromium-based and is corrosion resistant. As a result, it is ideal in extreme environments subjected to pressure and heat. When it comes to Inconel, there are a few different main types. Let’s take a look at some of the different types.
Inconel 600 is a nickel-chromium alloy with good high-temperature oxidation resistance. It is also resistant to chloride-ion stress-corrosion cracking, corrosion by high-purity, water, and caustic corrosion. As a result, this type of alloy is ideal for furnace components, chemical and food processing, nuclear engineering, and sparking electrodes.
This type is a high-temperature nickel-chromium-cobalt-molybdenum alloy that is both corrosion and oxidation resistant. Its main uses include gas turbine engine ducting and combustion liners. It is also popular in the chemical processing industry due to its resistance to a wide range of aqueous corrosive media.
Like the 600, Inconel 625 is a corrosion and oxidation-resistant nickel-base alloy. It has outstanding strength and toughness in the temperature range cryogenic to 2000ºF. This is because of the solid solution effects of columbium and molybdenum. This type of alloy can be found in heat shields, furnace hardware, gas turbine engine ducting, combustion liners and spray bars, chemical plant hardware, and special seawater applications.
