I would check both Fluids and Mechanical tools.  Both stress cracking and abrasive wear are more mechanical processes.

Fluent 23R2 has a corrosion tool that will model corrosion that arises from electron transfer (rusting etc ..)  This has some built-in chemistry models for water chemistry in acid, CO2, H2S and mixed environments.  The focus is on the details of the electrochemistry and movement of chemical species.
