"Caustic embrittlement" was first used to describe the cracking of riveted mild steel boiler plates due to local deposition of concentrated hydroxide at temperatures of 200 to 250oC (400 to 480oF). It was later known as "stress corrosion cracking" which was in turn replaced by "environmental cracking".

The two classic cases of stress-corrosion cracking are "season cracking" of brass, and the "caustic embrittlement" of steel. Both of these obsolete terms describe the environmental conditions present which led to stress-corrosion cracking.

The most significant contributors to boiler waterside corrosion are dissolved oxygen, acid or caustic in the water and a high temperature. If any of these are uncontrolled, severe pitting, gouging and embrittling of the tube metal can occur, which will ultimately lead to failure.

Is the water meant for use in a boiler ? If so, where is the (caustic ?)corrosion observed, in the boiler or further on in the system. Are any other chemicals added ? Do you know anything about the quality of the return condensate?
