Nickel-based alloys

Nickel-based alloys are a class of alloys that have high strength and a certain resistance to corrosion at high temperatures from 650 to 1000℃. According to the main performance is 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. 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

Nickel-based alloys are used in many fields, such as
1、Ocean: marine structures for sea environment, seawater desalination, seawater aquaculture, seawater heat exchange, etc.
2、Environmental protection field: flue gas desulfurization device of thermal power generation, waste water treatment, etc.
3、Energy field: atomic power generation, comprehensive utilization of coal, sea tide power generation, etc.
4、Petrochemical field: oil refining, chemical chemical equipment, etc.
5、Food field: salt production, soy sauce brewing, etc. In the above many fields, ordinary stainless steel 304 is not competent, in these special areas, special stainless steel is indispensable and irreplaceable. In recent years, with the rapid development of the economy, as the level of the industrial sector continues to improve, more and more projects require a higher grade of stainless steel. With the growth of demand for nickel-based alloys in various industries. 2011 China's nickel-based alloy market size reached 23.07 billion yuan, a year-on-year growth rate of 19.47%. Therefore, the level of industry development is in a steady upward trend
