Inconel 330 Sheet & Plate

Inconel 330 Sheet & Plate (UNS N08330,1.4886)

Inconel 330 Sheet & Plate (UNS N08330, 1.4886) is a nickel-iron-chromium alloy designed for high-temperature and corrosive environments. It offers outstanding resistance to oxidation, carburization, and thermal fatigue, making it a preferred material in industries such as heat treating, petrochemical processing, and power generation. The alloy maintains strength and stability over a wide range of temperatures, even under cyclic thermal loading. Its ability to resist cracking in oxidizing and carburizing conditions ensures long service life in demanding applications.

 

Key Properties

  • High-Temperature Resistance: Excellent performance in temperatures up to 1150°C (2100°F), maintaining mechanical strength and oxidation resistance.
  • Corrosion Resistance: Superior resistance to oxidation, carburization, and nitridation in both oxidizing and reducing atmospheres.
  • Thermal Stability: Exceptional resistance to thermal fatigue and cyclic heating, making it ideal for high-temperature processes.
  • Strength and Ductility: Retains good mechanical properties, including tensile strength and toughness, even at elevated temperatures.
  • Weldability: Suitable for welding with conventional techniques while minimizing post-weld treatments.

Corrosion Resistance

  • Oxidation Resistance: Nickel 330 exhibits excellent resistance to oxidation at high temperatures, typically up to around 2200°F (1200°C). This makes it suitable for use in high-temperature environments where other materials might degrade.
  • Carburization Resistance: The alloy is highly resistant to carburization, a process where carbon diffuses into the metal, potentially weakening it. This resistance is crucial in applications involving exposure to carbon-rich atmospheres.
  • Sulfur Resistance: Nickel 330 also shows good resistance to sulfur-containing gases and other aggressive chemicals. This makes it suitable for use in environments where sulfur compounds might be present.
  • General Corrosion: In general atmospheric or aqueous environments, Nickel 330 performs well, though its primary advantage is in high-temperature settings. For non-high-temperature applications, other nickel alloys or stainless steels might be more appropriate depending on the specific corrosion challenges.
  • Acid Resistance: While it has decent resistance to certain acids, for applications involving strong acids or acidic conditions, other materials with better acid resistance might be required.

Fabrication Data

  • Welding: Nickel 330 can be welded using common techniques such as TIG and MIG welding. Preheating and post-weld heat treatments may be necessary to avoid cracking.
  • Machining: The alloy machines relatively easily with standard tools. However, cutting speeds should be reduced compared to softer materials to avoid work hardening.
  • Heat Treatment: Generally not required. The material is used in the as-processed state for many applications.
