1、Definition: The high-temperature alloy material of the parts directly prepared by the casting method.<br>
2、Type: According to the composition of the matrix, it can be divided into iron-based casting superalloys, nickel-based casting superalloys and drill-based casting superalloys. According to the crystallization method, it can be divided into four types: polycrystalline casting superalloy, directional solidification casting superalloy, directional eutectic casting superalloy and single crystal casting superalloy. Most of the cast superalloys are polycrystalline cast superalloys.<br>
Application: Manufacturing aircraft engine blades, heat-resistant parts of fuel turbines, turbocharger blades, etc.<br>
1. Deformed superalloy refers to a type of metal material based on iron, nickel, and cobalt that can resist oxidation or corrosion in a high temperature environment above 600 ℃, and can work for a long time under a certain stress.<br>
2. Brands: Hastelloy x, Hastelloy R-135, Nimonic 80A, Nimonic 90, Incoloy901, Incoloy903, Inconel718, Inconel x-750, Udimet500, etc.
1. Corrosion resistant alloys have unique corrosion resistance and even high temperature corrosion resistance in many industrial corrosive environments, and have high strength, good plasticity and toughness, and can be smelted, cast, cold and hot deformed, processed and formed and welded. They are widely used In petrochemical, energy, marine, aerospace and other fields.<br>
2. Brands: Hasetlloy c-276, Hasetlloy c-4, Hasetlloy B, Hasetlloy G-3, ALLOY20cb3, Incoloy 800H, Incoloy 825, Inconel600, Inconel690, etc.
The high-temperature strength is higher than that of iron-chromium-aluminum, and it is not easy to deform under high-temperature use. Its structure is not easy to change, its plasticity is better, and it is easy to repair. Disadvantages: Due to the use of rarer nickel metal materials, the price of this series of products is up to several times higher than that of iron, chromium and aluminum, and the use temperature is lower than that of iron, chromium and aluminum.
