NS331 alloy material overview and application:
NS331 nickel-based alloy refers to a class of alloys with comprehensive properties such as high strength and certain oxidation and corrosion resistance at high temperatures of 650 to 1000 °C. According to the main properties, it is subdivided into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based alloys, nickel-based fine gold and nickel-based shape memory alloys, etc.: High-temperature alloy applications: In many fields, such as
1. Ocean: marine structures in sea areas, seawater desalination, mariculture, seawater heat exchange, etc.
2. Environmental protection field: flue gas desulfurization device for thermal power generation, wastewater treatment, etc.
3. Energy field: nuclear power generation, comprehensive utilization of coal, ocean tide power generation, etc.
4. Petrochemical field: oil refining, chemical and chemical equipment, etc.
5. Food field: salt making, soy sauce brewing, etc.
Classification of NS331 according to performance:
--The superalloy NS331 is named because it still does not have a sensitization tendency after 50 hours of heat preservation at the temperature.
- Corrosion-resistant alloy NS331 due to its ability to resist pitting corrosion and crevice corrosion in various corrosive media in oxidizing and reducing environments. It is named after its resistance to mineral acid corrosion and no stress corrosion cracking due to chlorides.
--The deformed alloy NS331 is named after the hot and cold deformation processing.
--Cast alloy NS331 is only for some parts that can only be formed by casting.
