http://www.j4stainless.com/ it seems to perform on par with 300 grade stainless the breakdown in this link states that J4 is only slightly less corrosion resistant to pitting than 304 and superior in this aspect to 201 and it held out much longer to stress corrosion cracking than 304 and its 50% stronger so even though the concord kettles are only 1 mm thick they are much stronger than a comparable thickness 304 kettle...(compromising in other areas im sure)...Again not that it matters much for our application.

I wasnt thrilled to learn that J4 was mainly from India as I've heard some scary things about the metals coming from there... These kettles could have come from an old recycled oil tanker or nuclear sub for all we know... I read that they were caught making radioactive metals a few times too... still it would be silly to stereotype all metals from the worlds largest recycler based of a few bad apples right? I had read in an article that Even the US government helped form a dummy corp to send its scrap ships there to be broken up by barefoot workers and hazardous chemicals dumped into the sea without any liability... I dont know how true that is but they are the worlds largest ship wrecking yard. I did hear they recently gave the workers shoes and hardhats due to the public outcry but still use children for the tight space work and wire separation.
