Since we know that high-temperature alloy castings with excellent performance and a special purpose, and that its production of raw materials - whether superalloys have to be mastered, such as its category, its main purpose, and so on. Xiao Bian has a good summary of the answers, we hope to help everyone.

Superalloy can simply dust three categories, mainly temperature as a basis for classification, namely 760 ℃ high temperature materials, 1200 ℃ 1500 ℃ high-temperature materials and high-temperature materials. No matter what kind of high-temperature alloys, which have excellent high temperature strength, good resistance to oxidation and hot corrosion resistance, fatigue resistance, fracture toughness, such as performance, has become one of the key irreplaceable material.
For now, 1200 ℃ 1500 ℃ high-temperature materials and high temperature materials are not used, instead of the maximum should be 760 ℃ high temperature materials. This material can be further subdivided, for example by matrix elements distinguish the words, including iron-based superalloys, nickel-based superalloy and cobalt-based superalloys are several; but if prepared to work as a basis, then there are high-temperature alloys, cast high temperature alloys and powder metallurgy superalloy; and so on.
Talking about the use of high temperature alloys in many industries are involved, one of the most well-known is to be used to make aviation, ships and industrial gas turbine turbine blades, vanes, turbine disks, high-pressure compressor disk and the combustion chamber and other high-temperature components.
