摘要：

This paper is the second in a series of two papers where we report results from laboratory-scale corrosion studies in which tailor-made well-characterized synthetic alkali salt deposits were used for corrosion testing of typical kraft recovery boiler super-heater steel materials. The corrosion testing was done in temperatures ranging from 450 to 600 degrees C. Six different alkali salts and six different steel types were used in the tests. In the first paper we reported generally on the corrosion tendencies of the six steels. In this second paper we continue the corrosion behavior mapping of the tested steels. (C) 2009 Elsevier Ltd.
