GERMANIUM-BEARING FERRITIC STAINLESS STEELS |
| 摘要 |
Germanium-bearing ferritic stainless steels are provided. A raw stainless steel-based material may have trace amount of germanium added. The raw material may be with iron and chromium as the primary components and such raw material when having germanium added could be used for the preparation of the germanium-bearing ferritic stainless steels. The trace addition of germanium may help the forming of passivation film, improve the stability of the passivation film and repairing capability of the same, enhance anti-corrosion capability of alloy, and turn pitting corrosion into general corrosion. |
