The pulp & paper industry has traditionally used stainless steels and nickel alloys in many applications. Nickel base alloys have performed well in batch or continuous pulp digester operations as well as in doctor blade applications where corrosion and wear resistance are needed. Stainless steels are being used to avoid iron contamination of the product paper and to resist process corrosion.
The following paper offers a very comprehensive guideline on materials selection for pulp & paper applications. It has been prepared to provide mill engineers with a good overview of the wrought and cast alloys used in sulphate and sulphite mills. The paper is application oriented and is a useful reference for mill engineers concerned with materials of construction in everyday use.
