Chromium! That's the key alloying element that gives stainless steels their excellent high-temperature corrosion resistance. I'm confident that's the right answer.

Okay, let me think this through. High-temperature corrosion is often caused by oxidation, so I'm guessing the answer has to do with an element that forms a protective oxide layer.

I've got a good strategy for this. I'll start by eliminating any options that don't seem directly related to self-maintenance, then try to identify the most comprehensive or user-friendly tool from the remaining choices.
