OXIDATION RESISTANT FERROUS BASE FOIL AND METHOD THEREFOR |
摘要 |
Aluminum coated ferritic base metal foil formed by cold reduction of hot dip aluminum coated ferritic steel strip containing from 10% to about 35% chromium, up to 3% aluminum, and up to 1% silicon, the foil having a ratio of aluminum coating thickness on both sides to base metal foil thickness of at least 1:10, with at least 4% by weight total aluminum. The method of production includes heating the foil in an oxidizing atmosphere within specified temperature and time limitations to provide a porous surface having a thin layer of aluminum oxide. The foil is adapted for fabrication into monolithic support structures for catalytic converters for internal combustion engine exhaust systems. |
