What are the classification and characteristics of nickel-based corrosion resistant alloys?
Author:
Nickel-based alloys are a class of alloys that have high strength and oxidation corrosion ability at high temperatures of 650 to 1000°C. According to the main performance is subdivided into nickel-based heat-resistant alloys, nickel-based alloys, nickel-based alloys, nickel-based precision alloys and nickel-based shape memory alloys. High-temperature alloys are divided into iron-based high-temperature alloys, nickel-based high-temperature alloys and cobalt-based high-temperature alloys according to the different substrates. Among them, nickel-based high-temperature alloys are referred to as nickel-based alloys.
The nickel-based corrosion-resistant alloy elements are copper, chromium and molybdenum. It has good comprehensive performance and can resist various acid corrosion and stress corrosion. The application (produced in the United States in 1905) is nickel-copper (Ni-Cu) alloy, also known as Monel alloy (Monel alloy Ni70Cu30); In addition, there are nickel-chromium (Ni-Cr) alloy (nickel-based heat-resistant alloy, heat-resistant corrosion alloy in corrosion-resistant alloy), nickel-molybdenum (Ni-Mo) alloy (mainly refers to Hastelloy B series), nickel-chromium-molybdenum (Ni-Cr-Mo) alloy (mainly refers to Hastelloy C series), etc. At the same time, pure nickel is also a typical representative of nickel-based corrosion resistant alloys. These nickel-based corrosion-resistant alloys are used to manufacture components for various corrosion-resistant environments such as petroleum, chemical, and electric power.
