Hmm, this question is making me thirsty. Maybe I should've had my morning coffee before tackling this exam.

HF? Heck, I wouldn't use any of those fancy metals for my truck! Just grab me some good ol' duct tape and we're good to go.

Wait, is this a trick question? I thought all metals were fair game for HF. Guess I need to brush up on my materials knowledge.

Oof, gotta be careful with those stainless steels. The 400 series is a no-go, but the 300 series might hold up better.

Definitely not carbon steel! That's just asking for trouble in an HF environment.

I'm pretty sure 400 Series SS is not suitable for HF service, but I'm not certain about the 300 Series.

I'm not sure about this one, but I think I'll go with D as well based on what Bulah and Ernest said.

I agree with Bulah, both A and C are not suitable for HF service due to their susceptibility to corrosion.

I think the answer is D, because 300 Series SS and 400 Series SS are generally not suitable for HF service.
