Catastrophic Failure of Stainless Cooking Pot 1

[AdamPrince2]

I saw a cooking pot that was made of stainless steel. It was used to cook potato soup. After cooking a restaurant owner decided to soak the pot in hot soapy water over night in the sink. The next day he found the pot literally cracked up like a banana peel! I have attached a photo. What failure mechanism would cause such a spectacular failure of a cooking pot?

I'm totally ignorant about SCC. I'm going to Google it now, but...

Was thermal shock involved, i.e. hot stove to relatively cool hot water?

Would it have happened if the pot had been left to cool on the stove?

[edit]I've had a quick read and it would seem to me that it's time had come, and there was no specific event that caused it to fail. Chemical inclusions seem to promote the failure, but the actual time of failure is unpredictable. Is this correct?[/edit]
