Superalloy materials divided into three categories: 760 ℃ high-temperature materials, 1200 ℃ 1500 ℃ high-temperature materials and high-temperature materials, the tensile strength of 800MPa. Or that refers to high-temperature metallic materials at more than 760--1500 ℃ certain stress conditions and long-term work, with excellent high temperature strength, good resistance to oxidation and hot corrosion resistance, good fatigue properties, fracture toughness, such as performance, It has become a military and civilian gas turbine engine hot section indispensable key material.
