skineedog Posted September 13, 2016 Author Report Share Posted September 13, 2016 Using the default coil setup on the Wire Wizard page of 30 AWG, 2mm, 8 wraps, the TC Precision number for Stainless Steel 316L is 879 and Nickel 200 (TFR) is 780. I thought nickel was the more accurate of the 2 yet the TC Precision number is lower with the nickel than the SS. If the wire with the higher TC precision number is the more accurate wire, than why is SS so difficult? I suspect it's the curve that's important. If that's the case, what value do the "TC Precision" numbers have? If one cannot/should not rely on this number when selecting a TC wire, what should one use? ( I realize there are many variables dependent on the individual. I ask strictly based on accuracy of the wire.)Considering the difficulty mods have dealing with SS, particularly with 316, why is it so popular and not 430? The TC number according to SE is considerably higher for SS 430 at 1105 with the aforementioned coil specifications. Link to comment Share on other sites More sharing options...
dwcraig1 Posted September 13, 2016 Report Share Posted September 13, 2016 My thoughts on the reason for 316 being in demand more than 430: 316 is a higher grade used for medical equipment. 316 was being used with mechanical's early on as it is what was availible (welding wire) Just my opinion here.The resistance change between cold and hot coil is to be considered, the more change the easier for the board to work with it. 1 Link to comment Share on other sites More sharing options...
Dampmaskin Posted April 19, 2017 Report Share Posted April 19, 2017 Sorry for the late answer, but I recently wrote a blog post where I try to explain the meaning and the reasoning behind the TC precision number in the Wire Wizard.http://blog.steam-engine.org/2017/04/qa-tc-precision/ Link to comment Share on other sites More sharing options...
baklar13 Posted April 26, 2017 Report Share Posted April 26, 2017 Thank you for the blog post sir! Now that I understand that my TC problems have been solved. I was building my ss coils at half the resistance they should be. I now have an excellent tc vape. Link to comment Share on other sites More sharing options...
