**This paper will focus on the use of nickel in stainless steels and nickel alloys in preventing corrosion in severe applications within the chemical process and related industries. It will begin with an overview of the available nickel-containing alloys and discuss conditions under which they should be used. The role of nickel in these alloys will be explained. It will also summarize their resistance to general and localized corrosion attack. Examples of the use of nickel-containing alloys will be presented which will show which alloys are successful in a wide range of applications, including production of the common acids and alkalies. Where appropriate, comparisons will be made with other alloys being used under similar conditions emphasizing the benefits of nickel-containing alloys.****
