| Nickel-based alloys refer to a class of alloys with high strength and certain resistance to oxidation and corrosion at high temperature of 650 ~ 1000 ºC. According to the main performance, it is further subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys. According to different substrates, superalloys are divided into: iron-based superalloys, nickel-based superalloys and cobalt-based superalloys. Nickel-based superalloy is referred to as nickel-based alloy. |
| According to the main performance, it is further subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys and nickel-based shape memory alloys. |
| The main alloying elements are copper, chromium, and molybdenum. It has good comprehensive performance and can resist various acid corrosion and stress corrosion. The earliest application (produced in the United States in 1905) was nickel-copper (Ni-Cu) alloy, also known as Monel alloy (Monel alloy Ni 70 Cu30); in addition to nickel-chromium (Ni-Cr) alloy (that is, nickel-based heat resistant alloy , Heat-resistant corrosion alloys in corrosion-resistant alloys, nickel-molybdenum (Ni-Mo) alloys (mainly referring to Hastelloy B series, domestic professional corrosion-resistant alloy production enterprises include Beijing Iron and Steel Research Institute, Bao titanium group rare metal materials Companies, etc.), nickel-chromium-molybdenum (Ni-Cr-Mo) alloys (mainly referring to Hastelloy C series, domestic professional corrosion-resistant alloy production enterprises include Beijing Iron and Steel Research Institute, Beijing Rongpin Technology Co., Ltd., Baotai Group rare Metal Materials Company, etc.) 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 mainly used in the manufacture of parts for various corrosion-resistant environments such as petroleum, chemicals, and power. |
| Most nickel-based corrosion-resistant alloys have an austenite structure. In the state of solid solution and aging treatment, there are intermetallic phases and metal carbonitrides on the austenite matrix and grain boundaries of the alloy. Various corrosion-resistant alloys are classified according to composition and their characteristics are as follows: |
| The corrosion resistance of Ni-Cu alloy is better than nickel in reducing media, and it is better than copper in oxidizing media. It is resistant to high temperature fluorine gas, hydrogen fluoride and hydrofluoride in the absence of oxygen and oxidants. The best material for acid (see metal corrosion). |
| Ni-Cr alloy is also a nickel-based heat-resistant alloy; it is mainly used under oxidizing media. Resistance to high temperature oxidation and corrosion of sulfur, vanadium and other gases, its corrosion resistance increases with increasing chromium content. Such alloys also have good resistance to hydroxide (such as NaOH, KOH) corrosion and stress corrosion resistance. |
| Ni-Mo alloy is mainly used under the condition of corrosive reducing medium. It is the best alloy resistant to hydrochloric acid corrosion, but in the presence of oxygen and oxidants, the corrosion resistance will be significantly reduced. |
| Ni-Cr-Mo (W) alloy combines the properties of the above Ni-Cr alloy and Ni-Mo alloy. It is mainly used under the condition of mixed oxidation-reduction medium. Such alloys have good corrosion resistance in high-temperature fluorinated hydrogen, in hydrochloric acid and hydrofluoric acid solutions containing oxygen and oxidants, and in wet chlorine at room temperature. |
| Ni-Cr-Mo-Cu alloy has the ability to resist sulfuric acid corrosion, and also has good corrosion resistance in some oxidation-reducing mixed acids. |
