What types of alloys are included in nickel-based alloys?

Nickel-based alloys are primarily nickel-based alloys that are widely used in applications in high-temperature, high-pressure, and corrosive environments. They typically contain multiple elements to enhance their properties. Here are some common nickel-based alloy types and their main components:

Inconel series:

Inconel 600: mainly composed of nickel (about 72%) and chromium (about 15%), has good high temperature resistance and corrosion resistance, and is commonly used in chemical equipment and gas turbines.

Inconel 625: Contains nickel (approximately 58%), chromium (approximately 22%), and molybdenum (approximately 9%), and has excellent high temperature and corrosion resistance. It is commonly used in aviation, chemical, and marine environments.

Inconel 718: Contains nickel (about 50%), chromium (about 19%) and iron (about 18%), and is widely used in high-temperature structural components such as aero-engines and turbines.

Hastelloy series:

Hastelloy C-276: contains nickel (about 55%), chromium (about 16%), molybdenum (about 16%) and iron, and has excellent corrosion resistance, especially in strong acid and alkali environments. It is commonly used in chemical equipment.

Hastelloy B-3: The main components include nickel (about 65%), iron, chromium, and molybdenum, which have excellent resistance to hydrogen chloride and chloride corrosion and are commonly used in the chemical industry.

Monel series:

Monel 400: The main components are nickel (about 63%) and copper (about 29%), which have strong corrosion resistance and are especially suitable for marine environments, chemical and petroleum industries.

Monel K-500: Similar to Monel 400. but with the addition of aluminum and titanium to give it higher strength and hardness, it is widely used in aerospace and marine engineering.

Nitronic series:

Nitronic 60: Contains nickel (approximately 75%), chromium, and manganese for excellent wear and corrosion resistance, and is commonly used in food processing, chemical, and nuclear industries.

Other nickel-based alloys:

Nimonic series: such as the Nimonic 80A, which is mainly used in high temperature applications and has good oxidation resistance and strength.

C-22 alloy: containing nickel (about 56%), chromium, molybdenum, etc., has excellent corrosion resistance and is widely used in chemical, petroleum and marine environments.

The properties and compositions of these alloys vary depending on the application environment. Generally speaking, the main advantages of nickel-based alloys are their excellent high temperature resistance, corrosion resistance, and oxidation resistance. They are commonly used in aerospace, petrochemical, energy, and other industries.
