Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . A germanium-bearing ferritic stainless steels comprising a raw material containing chromium that is 15 to 25 in weight percentage (wt %), manganese that is 0.3 to 0.9 in weight percentage, silicon that is 0.15 to 0.30 in weight percentage, germanium 0.1 to 1.2 in weight percentage, and iron rounding up the remaining of the raw material. 2 . The stainless steels according to claim 1 , wherein germanium ranges from 0.1 to 0.3 in weight percentage of the raw material. 3 . The stainless steels according to claim 1 , wherein germanium ranges from 0.3 to 0.8 in weight percentage of the raw material. 4 . The stainless steels according to claim 4 , wherein germanium ranges from 0.8 to 1.2 in weight percentage of the raw material. 5 . The stainless steels according to claim 1 , wherein the raw material after being immersed in sodium chloride solution is uniformly corroded.
