I recall that 175 F is too high for Chloride SCC concerns, so I think it must be lower, maybe around 140 F?

I’m leaning towards 120 F being the right answer, but I’m not completely confident. It’s tricky with all the temperature limits.

I feel like we practiced a question similar to this, and I want to say it was around 150 F, but I could be mixing it up.

I'm drawing a blank on the temperature limit for 300 Series SS in sour water. I'll have to make an educated guess here. Maybe 150 F? I'll go with option C and hope for the best.

Okay, I've got this. The key is that 300 Series SS can be used in sour water service as long as the temperature is below the point where chloride SCC becomes a concern. I believe the limit is 140 F, so I'll go with option B.

Hmm, I'm a bit unsure about this one. I know 300 Series SS has some limitations in sour water, but I can't quite remember the exact temperature threshold. I'll have to think this through carefully.

This seems like a straightforward question about the temperature limit for using 300 Series SS in sour water service. I'll need to recall the information about chloride stress corrosion cracking to answer this.

Wait, are we talking about sour water or sour grapes? Either way, I'd keep it below 120 F, just to be safe. A) is the way to go, trust me.
