摘要 |
A hot-dip aluminium coated steel sheet having excellent corrosion resistance and heat resistance, comprising a steel substrate containing 3 to 18% chromium, not more than 0.02% carbon, 0.1 to 1.5% manganese, 0.005 to 0.08% aluminium, not more than 0.1% silicon, with the balance being iron and unavoidable impurities, and aluminium coating on said sheet substrate. The coated sheet may further comprises a coating layer of nickel or nickel-iron alloy (Ni: 1 to 99%) beneath the aluminium coating, or an A?-Fe-Si-Ni-Cr alloy coating layer of 1 to 10.mu. in thickness and containing 0.05 to 5% nickel, 0.2 to 10% chromium, beneath the aluminium coating. |
