Description:
This paper provides a good introduction to material selection in paper and pulp applications, specifically ‘Kraft’ digesters where materials are subject to aggressive conditions including contact with black and white liquers. Alloy S32550 (”2605”) was recommended for future digester fabrication given its superior performance over other alloys, including Alloy 2205 – supporting the use of Ferralium® in this application due to the similarity in specification.
