I haven’t been able to find any break down that shows corrosion principles in its own category. I have the 2.5 version of the pan global books, and the chapter is pretty dense, but it makes sense that it’s put into chemistry/metallurgy with how the certain metals may corrode (based on internal stress and chemical composition) and then seeing the break down of the chemical reactions during corrosion (hydrogen cracking/blistering, atmospheric conditions, sulphur and chlorides). Just didn’t want to completely skip over the chapter thinking it wouldn’t be tested… wouldn’t make sense. Thanks.

I actually just got my results back from TSSA (Ontario), 80%… I had one corrosion question which was something along the lines of if your makeup and feedwater began to raise in pH what would happen inside the boiler. I can’t remember the answers, I know they were something like: caustic corrosion, caustic embrittlement, boiler metal having acid attack. Something along those lines.. plenty of questions of how steel was made though… Thanks all
