This FeCrAl strip is widely used in high-temperature furnaces, including continuous and batch processing furnaces, as well as heating systems for chemical, metallurgical, and energy industries. It can serve as heating elements, support structures, or protective layers in environments reaching up to 1250°C. The versatility of the strip means it is compatible with various furnace designs and configurations, from vertical kilns to horizontal heat treatment units.
One of the most significant advantages of 0Cr19Al3 FeCrAl strips is their oxidation resistance. In high-temperature operations, standard steel or less specialized alloys can degrade quickly, leading to frequent replacements and downtime. DLX FeCrAl strips maintain their structural and chemical stability over extended periods, reducing maintenance costs and improving furnace uptime. Additionally, its consistent electrical resistivity ensures stable heating performance, an essential factor for precise thermal processing in industrial operations.
DLX understands that no two industrial processes are exactly alike. The 0Cr19Al3 FeCrAl strips can be customized in width, thickness, and length to meet specific furnace requirements. Whether clients need narrow precision strips for tight-fitting heating elements or broader rolls for large-scale installations, DLX offers tailored solutions. Surface finishing is another area of focus, with smooth, uniform finishes reducing the risk of scale formation and improving overall heat transfer efficiency.
