SS drippers toxicity concern - might be important

[Vaptor]

Recently I bought SS Nimbus clone. It had a strange odor on vaping and a lot more when the cap got hot. I could really taste it strong. I've cleaned it in many ways but smell was still there. So I changed mesh and coil from another vendor. Smell still there. Nothing helped till I decided to give the top cap a heat treatment using a blow torch. The top cap has changed color to gold (as SS does at high temps) and the smell is gone.
That got me rather concerned if a Nickel or other metals which might be carcinogenic were being released by the fairly low temperature in the atty. I doubt China SS drippers etc are made from food grade SS but even that apparently can release Nickel etc.
I just want to put this out and perhaps someone in metal industry might have an answer.
I was also getting same smell from DID clone SS mesh that came with it and never knew why till now.
If you're getting strange odor from your SS device, this could be it.

Did you ever get an answer to this? I have a new Origen that taste like #$#&& with all different types of coils, wicks and flavors. I can also smell the same thing i fast in the top cap and started trying to find the answer.

sounds fair a good heat treating will bond the crystal structure a bit more, plus it will burn off any machining lubricants that were not removed in washing ( I found that the Orange clean stuff works well)
but as far as carcinogenic material seriously doubt it SS is SS, for different applications the chromium,nickle,iron percentages are changed.
and besides the fillings for cavities were done with Mercury and silver mix.
