Surface on a stainless steel matrix |
| 摘要 |
A stainless steel comprising at least 20 weight % of chromium and at least 1.0 weight % of manganese is adapted to support an overcoating having a thickness from 1 to 10 microns of a spinel of the formula Mn<SUP>x</SUP>Cr<SUP>3-x</SUP>O<SUP>4 </SUP>wherein x is from 0.5 to 2. Preferably the overcoating is on chromia and has stability against chemical reaction at temperatures at least 25° C. higher than the uncoated chromia. |
