Characteristics, types, and applications of nickel based alloys
Nickel based alloys refer to a type of alloy that has high strength and certain resistance to oxidation and corrosion at high temperatures of 650-1000 ℃. According to their main properties, they are further divided 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. High temperature alloys are divided into iron-based high-temperature alloys, nickel based high-temperature alloys, and cobalt based high-temperature alloys according to their different substrates. Nickel based high-temperature alloys are commonly referred to as nickel based alloys.
Representative materials of nickel based alloys include:
1. Incoloy alloys, such as Incoloy800, mainly consist of:; 32Ni-21Cr Ti, Al; belongs to heat-resistant alloys;
2. Inconel alloys, such as Inconel600, mainly consist of:; 73Ni-15Cr-Ti, Al; belongs to heat-resistant alloys;
3. Hastelloy alloy, also known as Hastelloy alloy, such as Hastelloy C-276, mainly consists of:; 56Ni-16Cr-16Mo-4W; Belonging to corrosion-resistant alloys;
4. Monel alloy, also known as Monel alloy, such as Monel 400, mainly consists of:; 65Ni-34Cu; Belonging to corrosion-resistant alloys;
Nickel based alloys are used in many fields, such as:
1. Ocean: Marine structures in the marine environment, seawater desalination, seawater aquaculture, seawater heat exchange, etc.
2. Environmental protection field: flue gas desulfurization devices for thermal power generation, wastewater treatment, etc.
3. Energy sector: Atomic power generation, comprehensive utilization of coal, ocean tidal power generation, etc.
4. Petrochemical industry: refining, chemical equipment, etc.
5. Food industry: salt production, soy sauce brewing, etc. Among the many fields mentioned above, ordinary stainless steel 304 is not competent. In these special fields, special stainless steel is indispensable and irreplaceable. In recent years, with the rapid development of the economy and the continuous improvement of the industrial sector, more and more projects require higher grade stainless steel. With the increasing demand for nickel based alloys in various industries. In 2011, the market size of nickel based alloys in China reached 23.07 billion yuan, with a year-on-year growth rate of 19.47%. Therefore, the development level of the industry is steadily on the rise.
