I recently bought a set of stainless steel pans from Amazon (I live in the UK). The information on the product page says the material is 18/8 stainless steel. I believe this refers to a (common) type of 304 stainless steel, comprised of 18% chromium and 8% nickel.

But when the pans arrive, on the bottom of them, there is a number 275 (see image below).
That is on all of them, so it shouldn't indicate the diameter.

Therefore, could anyone suggest what this number means?
In particular, does this indicate the grade/type of the stainless steel? And if so, what is this type of material, and is there any indication/research on its implication to health as a cooking ware (sauce pan)?

I know some stainless steel products have a mark (e.g., on the bottom) stating the grade/type of the material. But I did not find 275 as a grade for stainless steel. The closest thing I found was S275 steel – not in the stainless category (if there is such a thing).

To be complete, there are 5 pieces in this set: 3 are stainless steel, 2 are stainless steel with non-stick coating.

The package says pans were made in India (not sure if it's useful or not).

    Is there any reason to believe that the number isn't simply the pan model, used by the mfr?

    Things to rule out: there is no way it's S275, that's mild steel and would rust. Also, just checked and India uses the same steel formulation IDs that the US does, so it's not an Indian number either.

    You could always reach out to Kaufmann directly and enquire. They may or may not tell you, but it might be your best bet on a definitive answer.

I have reached to the seller. It was third-party on Amazon, but it was directly linked from the brand's website, so I presume that is the reply from the manufacturer (or at least with a close contact with them).

They say the number 275 is the batch number, telling them when they were manufactured.
And they say they can confirm that the pans are 18/8 stainless steel.

Although there is still a little uncertain, I'll take their word.
