What are Alloy 330 Plates?
Alloy 330 Plates, also known as Incoloy 330 Plates, are made from a heat-resistant austenitic alloy composed mainly of Nickel, Chromium, and Iron. This alloy is designed to handle high temperatures and resist oxidation and carburization.
The UNS N08330 designation refers to the specific grade under the unified numbering system, which guarantees consistency and quality. These plates are widely used in furnace parts, heat exchangers, thermal processing equipment, and petrochemical plants.
Key Features of Alloy 330 / Incoloy 330 Plates
- Excellent high-temperature strength
- Superior oxidation and carburization resistance
- Good mechanical strength even at elevated temperatures
