“…In the event of a post weld heat treatment, the IC attack range is relatively strongly influenced by the chromium and nitrogen contents, as indicated by Figs. 92 (page 136) and to the great wealth of literature on the corrosion and precipitation behaviour of chromium-nickelmolybdenum steels and weld metals, in particular the following entries in our list of supplementary literature [33,38,41,42,44,45,46,213,214,215,216,218,219,265,266,400,401,402,407,408,409,411,413,414,415,443,447,448,470,480,482,485,486]. By increasing the contents of both elements, the beginning of the IC attack range is shifted to longer periods of time.…”
