    Hi all, I finally bought some 316L and have been tinkering with my serpent mini. I did a 24g spaced coil, i think 8 wrap 2.5mm id, anyway.

    I have a few concerns already. Now, i know SS can be dry burned, but to what extent? I've been trying some temp control and i am still learning how to wick the serpent mini, so after about 3 trys of dry burning and rewicking the last time i noticed a bit of a metallic taste.

    I took the tank off and the wick seemed saturated so its not that. I went into my bathroom and turned out the lights so i could fire it and see if there was any glowing, i blew on the coil while i fired it. Well it took me about 3 fires for a good few seconds until i saw it start to glow.

    Anyway i took out the wick and dry fired again and noticed the same metallic smell that i seemed to be tasting. Do you think im just dry firing it too much? Just to note, it came out to .27 and vaped from 30-35 watts, i lowered it to 20 watts when dry firing.

    Honestly, there isn't enough research to tell for sure. I dry burn mine but I don't dry burn after I rinse the coil off, I noticed a residue every time I do.

    Sounds like a short or hot leg in your coil. SS gives off a distinct taste and smell when shorted, as any Genesis user with SS mesh will tell you.

    Good oxidation resistance in intermittent service to 870°C ... Continuous use of 316 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important.

    So, dry burning to cherry color should be safe.

    I've been using 316L in my mechanical REOs for a month or so, after being a kanthal user for a long time. I like the SS.
    I've never seen any reason to dry burn any coil, regardless of material, beyond cherry red.

    Another question for the stainless steel users, is it normal for the coil to turn a brownish red color? It almost looks like rust. I THINK its just some caramelization from a juice i used in it, but i dry burned and re wicked and it tastes fine.

    Also I've been using this coil for about a week.

    I've been using plain old 316 28 guage for pushing a year. I notice that it can take a while to get rid of the hotspots. With a new coil sometimes hotspots come back. I can correct it by pulling the topcap off (rda), and just brushing the coil a few more times. Then may be the problem goes away and comes back in a while so repeat the proceedure and eventually the problem does not come back. Then after about 2 weeks and 100 ml of juice the coil loses it's sizzle, taste gets flat, time for a new coil. I use very low flavor percent with almost no gunking but the surface of the coil seems to get pitted or may be it's a very thin layer of gunk that doesn't want to come off. Also a new coil starts out showing lower than the predicted resistance, bounces around for a while and settles down after repeated brushing often done with wick and liquid in contact with the coil. I wish I understood hot spots and coil aging better.
