This present work is part of a study for adapting the composition of commercial super ferritic steels by increasing Mo content in the alloy so they can be used in petroleum plants that refine petroleum oils rich in sulphur compounds. The increase in Mo content in austenitic stainless steels increases the corrosion resistance in mediums that are rich in naphthenic acid or other sulphur complexes. They were first developed for use in heat exchangers and marine environments.
Super ferritic steels belong to a family of steels with Cr content greater than 25% and which also have Mo in their compositions.
