Haha, I bet the answer is D. 15%-20% because that's the range where the welder can take a coffee break and the weld won't crack!

I think I remember something about ferrite content being crucial for preventing hot cracking, but I'm not sure about the exact range.
WI

This is a tricky one. I'm torn between B and C, but I think I'll go with C since it seems to be the most specific range mentioned.

Okay, let me see. I remember learning that austenitic stainless steels need a certain amount of ferrite to avoid hot cracking. I think option C sounds right, but I'll double-check my notes just to be sure.

The question is asking about the ferrite content needed to prevent cracking, so I'm guessing the higher end of the range is better. I'll go with option D.
NE
Nenita
