Alloy 330 UNS N08330: Properties, Applications, and Benefits

Alloy 330 UNS N08330 is a high-performance austenitic stainless steel known for its exceptional resistance to oxidation and carburization at elevated temperatures. This nickel-iron-chromium alloy maintains strength and stability in environments up to 2200°F (1200°C), making it a preferred material for extreme temperature applications.

Key Material Characteristics

The alloy demonstrates outstanding thermal stability due to its high nickel content (34-37%) and chromium composition (17-20%). Its silicon content (1-2%) enhances oxidation resistance while maintaining good mechanical properties across temperature ranges.

Industrial Applications and Usage

Industries leverage Alloy 330 UNS N08330 for critical components in:

• Heat treatment fixtures and baskets
• Furnace retorts and radiant tubes
• Thermal processing equipment
• Chemical processing vessels

Performance in Extreme Conditions

The material exhibits remarkable resistance to thermal cycling and thermal shock, maintaining structural integrity through repeated heating and cooling cycles. Its low coefficient of thermal expansion contributes to this stability.
