Nickel / Nickel Alloy Steel ASTM B163 NO8825 Heat Exchanger Tube

Grade NO8825, commonly known as Inconel 825 or Alloy 825, is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. This composition provides excellent resistance to both reducing and oxidizing acids, stress corrosion cracking, and localized attack such as pitting and crevice corrosion. NO8825 is also known for its good mechanical properties at both room and elevated temperatures.

Key Features:

  • Corrosion Resistance: Excellent resistance to a wide range of corrosive environments, including sulfuric and phosphoric acids.
  • Stress Corrosion Cracking Resistance: High resistance to stress corrosion cracking in chloride-bearing solutions.
  • High Temperature Stability: Good mechanical properties and oxidation resistance at elevated temperatures.
  • Weldability: Good weldability with proper techniques and post-weld treatments.

Applications:

1. Chemical Processing Industry

  • Heat Exchangers: Used in heat exchangers where resistance to highly corrosive chemicals, including sulfuric and phosphoric acids, is essential.
  • Reactors and Pressure Vessels: Suitable for reactors and pressure vessels dealing with highly corrosive substances.
  • Piping Systems: Ideal for piping systems that transport aggressive chemicals at various temperatures and pressures.

2. Oil and Gas Industry

  • Offshore Platforms: Suitable for offshore oil rigs and platforms where exposure to seawater and corrosive environments is common.
  • Subsea Equipment: Used in subsea equipment due to its excellent resistance to stress corrosion cracking and pitting.
  • Refinery Equipment: Ideal for components in refineries that process sour gas and other corrosive substances.

3. Power Generation

  • Nuclear Power Plants: Used in nuclear power plant components exposed to aggressive cooling waters and corrosive environments.
  • Heat Exchangers: Suitable for heat exchangers in power plants due to its high thermal conductivity and corrosion resistance.
  • Steam Generators: Ideal for steam generators where high-performance materials are required.
