High-temperature alloys are a class of metal materials that exhibit excellent performance in high-temperature environments. They are widely used in aerospace, petrochemical, energy, and other high-temperature industrial fields. Traditional metal materials often experience creep, oxidation, erosion, and corrosion issues under high-temperature conditions, while high-temperature alloys can maintain good mechanical properties, oxidation resistance, and corrosion resistance under these extreme conditions.

Here are several common high-temperature alloy grades:

1. A286: A286 high-temperature alloy is an iron-based alloy that possesses excellent high-temperature strength and oxidation resistance. It can be used for long periods at temperatures around 700°C and exhibits good creep and fracture toughness. A286 is commonly used in the manufacturing of bolts, springs, and other structural components operating at high temperatures.

2. Nimonic 80A: Nimonic 80A is a nickel-based high-temperature alloy that offers excellent high-temperature strength and creep resistance. It can be used for long periods at temperatures around 815°C and exhibits good oxidation and corrosion resistance. Nimonic 80A is commonly used in the manufacturing of turbine blades, combustion chamber components, and heat exchangers operating at high temperatures.

3. Nimonic 90: Nimonic 90 is a nickel-based high-temperature alloy that provides high strength and good oxidation resistance. It can be used for long periods at temperatures around 950°C and exhibits good corrosion resistance. Nimonic 90 is commonly used in the manufacturing of nozzles, combustion chamber components, and turbine components operating at high temperatures.

4. GH1140: GH1140 is an iron-based high-temperature alloy that offers good high-temperature strength and oxidation resistance. It can be used for long periods at temperatures around 1000°C and exhibits good corrosion resistance. GH1140 is commonly used in the manufacturing of bolts, springs, and other structural components operating at high temperatures.

5. GH3625: GH3625 is a nickel-based high-temperature alloy that provides excellent high-temperature strength and oxidation resistance. It can be used for long periods at temperatures around 1050°C and exhibits good corrosion resistance. GH3625 is commonly used in the manufacturing of combustion chamber components, turbine blades, and heat treatment equipment operating at high temperatures.

These high-temperature alloy grades play important roles in their respective application fields and provide reliable material solutions for industries and aerospace sectors operating in high-temperature environments.
