About UNS N08330 (Incoloy® 330)

UNS N08330 is a nickel–iron–chromium alloy with added silicon, designed to offer:

  • Outstanding resistance to oxidation and carburization up to 1150°C (2100°F)

  • High mechanical strength at elevated temperatures

  • Excellent structural stability during long-term high-temperature exposure

  • Resistance to both oxidizing and reducing atmospheres

This alloy is ideal for equipment exposed to fluctuating temperatures, thermal cycling, and aggressive industrial atmospheres.
