Is to create the modern high temperature alloy parts and high temperature gas turbine power sector, energy, metallurgy, petrochemical equipment, and other important high-temperature metal parts. It at high temperature (600 ~ 1100 ℃) oxidation and gas corrosion atmosphere under heavy stress long-term use. Performance requirements of high-temperature alloys are mainly good thermal stability, heat resistance and the use of strong long-term organizational stability under the conditions and so on.
