Problem with SS is that it's still a relatively new material as far as the purpose of it being used as a heating element in Vaping is considered.
A lot of wire companies are selling spools of SS for cheap and we don't even know the quality of the wires.
For example, on the DNA200, the steamengine .csv profile for their 316L is actually based on the Gplat Elite 316L SS (material datasheet here:
http://www.crownalloys.com/MSDS/MSDS-STAINLESSSTEEL-BARE_2.pdf)
Based on the .csv settings, the TFR of thr Gplat 316L is actually giving an anaemic vape when i used UD's 316L.
Luckily, thanks to Jaquith on DNA200 forums, i was finally able to get the UD316L working properly on TC. He did a couple of trial and error testing by tweaking the original steamengine .csv for 316L.
In my opinion, it is critical in a wire designed as a heating element that the companies focus on resistive deviation and consistency.
The gauge, uniformity of the cross sections across the length of the wire as well as the iron distribution are all critical. In my opinion, micro scope cross sections of the wires should be done to look at distribution of buffers. That way, wire manufacturers can ship out spools of wires with good resistive conductivity.
In fact, it would be great if these wire companies could do more testing and come up with their own sets of TCR values for their products (as far as SS is concerned).
If not, TC on SS is gonna be pretty much a frustrating wild guess. But thats just my opinion lol.
