2535NbW + 800H Material Combination
This furnace cover uses a combination of 2535NbW and 800H materials according to the structural and operating requirements of the component.
2535NbW
2535NbW is a high-Cr, high-Ni heat-resistant alloy with niobium and tungsten additions, commonly selected for high-temperature furnace components where strength and structural stability are important.
Typical advantages include:
800H
800H is a nickel-iron-chromium high-temperature alloy widely used in elevated-temperature industrial applications.
Its useful characteristics include:
Using different materials in different sections allows the component design to be optimized according to the temperature, mechanical load, welding requirements, and local service conditions.
Cylindrical Closed-End Design
The product features a large cylindrical body with a closed end and flange-mounted connection.
This structure is suitable for applications requiring:
The cylindrical design also provides good structural continuity under thermal service.
Custom Dimensions
This project uses the specified diameter:
Ø563 × Ø531 mm
Other dimensions can be customized according to customer drawings, including:
