What Grades of Stainless Steel Are Considered Safe For Vaping?

[VaPreis]

I've been trying various builds on my AIOS tank, and the most successful have involved the use of Ekowool sleeved SS cable. However, in the style of builds I've been doing, it's occurred to me that I really don't need the cable so much as a small piece of rod that I can sleeve with Ekowool.

So I have been looking online for a small bit of Stainless steel rod but stopped myself from ordering something because I wasn't sure if the grade was considered safe for this sort of thing.

What I was looking at is 316 (marine grade?) grade SS rod. Is this generally safe, or should I be shopping for another grade?

316 is probably the best grade to use but several products have used as low as 304.

sounds interesting let us know how it goes.

I guess I don't understand the purpose of the rod. Are you going to sleeve the rod with ekowool all the way down into the tank?

No, not exactly. On the AIOS, the tank sits above the coil, so the juice wicks downward. The rod will enter the tank, but will simply be a platform to sleeve Ekowool below the tank.

Perfect! Thank you.

The purpose of the cable is to break the surface tension of the juice and allow the juice to climb up each individual strand in the cable. There is probably more surface area with equal od. cable than solid rod.

BTW there's commercial grade stainless, food grade etc. Prolly all work for that, the number is referring to the carbon content ie. How hard it is. I think...

That makes good sense, but I'm thinking in this setup, the wicking is more dependant on the placement of the ekowool. In which case, the cable is just more of an annoyance to sleeve than a solid rod would be.

There are dozens of grades of stainless. "Stainless steel" is a pretty generic term. There are grades that are magnetic, grades that aren't, grades that are heat treatable, grades that machine better than others, some grades are more corrosion resistant than others. Most RBAs are made of either 303 or 304.

Go for it and let us know how it turns out
I would try to go for 316 surgical grade
