I bought 28, 26 and 24 awg SS 317L a few weeks ago and cannot figure out why my supposedly stainless steel 317L builds are matching kanthal resistances. Just did 26 gauge 10 wraps of SS on 3mm thinking it would be around 0.7 ohms and it's come out at 1.3 ohms, which is approx what 26 gauge kanthal comes out at for 9 to 10 wraps on 3mm. This has been happening consistently on various amounts of wraps. Example, I did 12 wraps on 3mm diameter with 26 gauge. Should be about 0.8 to 0.9 ohms but it came out around 1.6 to 1.7 ohms. I also did 6 wraps which should be 0.4 to 0.5 and it came out at 0.9 to 1 ohm.
I can't remember if my 24 and 28 gauge are the same, I'll have to do some test builds, but anyway, I tested for magnetism using the magnets inside the door of my mod and none of these wires are magnetic, so they can't be kanthal. Any ideas? I also notice that on the first press of the button, the resistance starts lower and then about 2 or 3 presses after, it increases until it finds the resistance it stays at. Like this current build goes 1.1, 1.2, 1.3 and then stays there. Could my mod have an issue with detecting resistances? Certainly seems solid enough, nothing seems loose and the 510 pin connector isn't sprung loaded.
