Alloys as corrosion resistant materials

Abstract

There are two possible ways of combating corrosion in metal structures, i.e. either by external protection or by the use of a metal which will not corrode under the given conditions. It is well‐known that iron of extremely high purity will not corrode unless it is damaged. On the other hand such very high purity iron is impractical to manufacture on an industrial scale, nor would pure iron possess the right physical properties for most industrial applications. Hence the solution is to mix the iron with other materials until an optimum is reached in corrosion‐resistance and physical characteristics. This is an extremely complex art since the slightest change in composition affects the properties of the steel. This survey therefore only outlines the general characteristics of the alloys and greater details can be obtained directly from the manufacturers. The latter are also engaged in active research, and some of their recent developments are presented at the end of the article.
