740H alloy is suitable for processing into industrial parts in high temperature and highly corrosive environments.

Inconel 740H (often shortened to 740H) is a nickel-based superalloy with a variety of properties that make it suitable for specific processing materials and environments:

Hot corrosion resistance: 740H has extremely high hot corrosion resistance and can resist corrosion in complex corrosive environments such as sulfide and chloride. This property makes it an ideal material choice in the chemical and petroleum industries, especially for equipment and components operating in high-temperature and highly corrosive environments.
Mechanical properties: 740H maintains high strength and toughness even under high temperature conditions, which is crucial for equipment that needs to withstand mechanical loads at high temperatures.
Processability: Whether hot or cold working, 740H alloy shows good processability, helping to manufacture parts with complex shapes.
Resistance to coal ash/flue gas corrosion and steam oxidation: 740H also has excellent resistance to coal ash, flue gas corrosion and steam oxidation, making it an ideal choice for ultra-supercritical power station boiler superheater/reheater tubes and thick-walled pipes. Important material selection.
In addition, when considering processing the 740H alloy, it is necessary to note that due to its long-term exposure to high temperature conditions, the flaky eta phase may form in the alloy, which may have an adverse effect on the creep strength and ductility of the alloy. Therefore, during the design and processing process, special attention needs to be paid to the heat treatment and process conditions of the material to ensure that the performance of the final product meets the application requirements.
