jeninga75,
This is my advise on this: Whenever possible, buy MADE IN USA gear.
It is very clear there are numerous grades of SS. Many USA companies shift production overseas and send materials specifications thinking this is good enough, there is way more than that. Because of this, customer's kitchens are the labs where thegear they sell is tested. A company may produce a great product here in USA, this is due to years of development, testing and fine tuning. By switching production overseas, the material composition control to ensure identical performance is much harder because there are factors the company can't control anymore, like raw material supplier, material recycling grade or material additives that are not part of the material specification. To make matters worst, steel is in short supply making harder to find an exact grade of material (at the appropriate price) for certain application.
I am not dissing overseas manufacturers; there are exceptions to this rule (also European manufacturers have very high standards), but IMHO, this is probably the cause for seeing those the rust spots several ppl mentioned here.
As an example: I have rust on my kitchen sink stainless steel drain. Believe me, I never put the thing in the dishwasher! LOL
