Lanthanum-modified high-temperature alloy |
摘要 |
A high-temperature steel of chromium, nickel and tungsten modified with a lanthanum addition and balanced compositionally to provide a combination of good oxidation resistance and high temperature strength; chromium is present within the range of 19 to 22%, nickel is present within the range of 30 to 45%, tungsten is present within the range of 1 to 4% and lanthanum is present within the range of 0.02 to 0.25% with the lanthanum addition providing the oxidation resistance and the combination of elements being balanced to achieve structural stability and thus high strength at elevated temperature.
