ya im not sure i even want to try using it tbh. not a fan of using stuff that i dont know what it is.WoW!
It AIN'T 52/48 for sure. [emoji85]
the label says hard wire on it... it wasnt joking lol

http://www.steam-engine.org/coil.asp?si=false&a=true&mat=nft52&r=0.28&hfnw=40&awg=26&id=2.7178I made a coil for my Magma, here's specifics: 2.7 mm id, 8 wraps contact, short legs. It came out to .480Ω where Wire Wizard puts it at just under 0.3Ω. Atomizer unfired 0.548Ω and fired 0.606Ω.
On a 2.5mm coil master rod, 6 wraps and it sprung to 2.75mm. After spacing the coil, it was about 2.78mm, reading 0.314 ohm. Setting SE value to 0.48 mm, it said it should be 0.315 ohms.
For some reason I decided to do some checking again after looking at the data sheet a few posts back.
All I checked was cold resistance (0.508Ω) and resistance at 450F (0.638), not much of a rise there.
I said a Heat Flux of 132K... Holy Snappin' Ars*olesI've found that if you have less then 132375 mW/in² the coils will have a noticeably slow ramp up & given enough air (Mutation Xv4) it may never get to temp setting.
You guys that are getting 3-6 months on your Ti coils what brand are you using.
Instead of getting close to 0.3Ω I got close to 0.5Ω (cold)Now I'm really scratching my head. dwcraig & Landman Please confirm I have these builds right:
1st dwcraig1 built this with 26ga NiFe52? from Unkaman
http://www.steam-engine.org/coil.asp?si=false&a=true&mat=nft52&r=0.28&hfnw=40&awg=26&id=2.7178
And instead of .28Ω you got .606Ω
2nd Landman built this with 24ga NiFe52? Also from Unkaman
http://www.steam-engine.org/coil.as...999999999997&ll=5.0038&ws=0.38099999999999995
And got .314Ω instead off .315Ω predicted by SE ?????, but as you can see from the above SE build Landman's described
build would be .17Ω
To get a SE predicted .315 you'd need 12.5 wraps per the build below.
http://www.steam-engine.org/coil.as...999999999997&ll=5.0038&ws=0.38099999999999995
If I understand correctly then both the 26 & 24ga have resulted in roughly double the resistance they should be & per dwcraig a very low TCR per dwcraig
If this is NiFe 52 then .508Ω @ 68°F should be .943Ω @ 450°F If TCR is .001 then it would be .617Ω at 450°F
Based on resistance & TCR it sounds more like 316 or 317SS
One thing is for sure it's not NiFe 52
I had just woke up when I read this post. I missed the part about dry burning before wrapping and was totally baffled as to how to wrap it all stiff like that. I'm awake now and have read it again ...DUHAlright, I took a 6" piece of reported 24 ga NiFe52 to test first. SE says it should be .51mm but this measures .48mm. Off the spool, it was crazy stiff. One large loop on the Velocity deck, ohms reported - DNA200 - 0.652, DNA40 - 0.603, and SXMM - 0.61. Dry burned and cleaned with IPA on a napkin, no marks so it seems very clean. On a 2.5mm coil master rod, 6 wraps and it sprung to 2.75mm. After spacing the coil, it was about 2.78mm, reading 0.314 ohm. Setting SE value to 0.48 mm, it said it should be 0.315 ohms.
Edit: forgot to add using the coil in a STplus.
Using the SE csv curve, it wouldn't work with temp control... it kicked to power mode every time. I changed it to the TCR value of 0.00404 and it would stay in temp control reporting a temp of only ~155 F while vaping. Using the SE csv for SS304 and it seemed to work much better.

My order of the 3 sizes was supposed to delivered today but instead it went from Kansas City, KA all the way to Kansas City, MO taking 2 days via USPS and is just sitting there.No tracking yet, only the number.
Will certainly post on receipt AND my comparison, even if someone else does ahead of me...
Just because it doesn't indicate that it departed doesn't mean it didn't already.My order of the 3 sizes was supposed to delivered today but instead it went from Kansas City, KA all the way to Kansas City, MO taking 2 days via USPS and is just sitting there.![]()
It's not 317 but then still about the same for us.I just got a shipping notice today for the wire so I don think it called back. I hoe he takes returns because I'm not going to need anymore ss317.
ya im not too happy with itI just got a shipping notice today for the wire so I don think it called back. I hoe he takes returns because I'm not going to need anymore ss317.
