By adding the Al element, a continuous and dense Al₂O₃ oxide film with high thermal stability can be automatically formed under high-temperature conditions. It has excellent resistance to high-temperature creep, high-temperature oxidation and corrosion, with a working temperature as high as 1200℃. It significantly improves the catalytic efficiency and capacity during the reduction process, reduces energy consumption and extends the service life of the furnace tube.
