| 520 | 3 |a“As part of a larger research project aimed at determining the effect of alloying elements upon the corrosion behaviour of ferritic stainless steels, aqueous corrosion tests were carried out upon AISI Type 430 stainless steels containing additions of each of Mo, V, W, Ta, Si, Re, Pd and Ge, and upon a control steel, AISI Type 304 stainless. It was found that Mo, V and W additions each conferred improved corrosion resistance in non-oxidizing normal sulphuric and normal hydrochloric acid solutions. W was the most effective and V the least effective at the lower addition levels, below 1%. Mo and, to a lesser extent, Re were the only additions that conferred increased resistance to oxidizing normal ferric chloride solution, while all the additions except Re and Ta were, to at least some extent, deleterious to corrosion resistance in boiling 65% nitric acid. Pd additions were unique in that, in the range 0.46-1.91%, they brought about passivation in normal sulphuric acid, thus outperforming AISI Type 304 stainless steel in that medium. However, Pd additions of less than 0.46% were deleterious to corrosion resistance in sulphuric acid, whereas Pd additions at all levels were deleterious to corrosion resistance in the other test solutions. A Type 430 steel containing 3.11% Mo showed corrosion resistance most nearly approaching that of Type 304 steel in the sulphuric acid, hydrochloric acid and ferric chloride solutions. However, this steel had extremely poor resistance to boiling 65% nitric acid, while the Type 304 steel (as expected) showed excellent resistance to this medium"--Abstract, p. i. |
