Hard to say, the differences are small, all work. 550F - 600F should be hot. I posted V3 for those who want a cooler vape.

On UD I personally prefer the V4 and on 'Grade D' SS316L from Uwell ie Crown I used V3 and of the 3.5 vs 3.25 on the 'Crown' preferred 3.25. 

I think the 'problem' or at least it is to me, is the preheat. When I both use a lower 1.5~2.5 Punch AND 0.5 Seconds AND a lower Preheat wattage than the Power wattage then I had NO BURNING or aka over-heating.

When someone says V3 too cool and V4 too hot at higher temps .. then the answer is obviously fine tune the hotter temps and find a happy medium.

Frankly and IMHO Evolv needs to revamp the Preheat; example Preheat power (wattage) as a percentage of the Power that the user sets dynamically; 10%-200%. The reason is it's, to me, a PITA to change one value easily BUT the other requires a PC intervention to access!

It should but it won't be exact, G-plat / SS317L is close but not exact to SS316L. The biggest difference is between SS304 and SS316L / SS317L wire.

Related question for the group... Steam Engine's 316 and 316L look almost identical, except for a tiny change in the 2nd decimal place of that last breakpoint on the curve.

Will it matter?

I have both 316 and 316L wire coming soon and have maxed out my profiles. If possible, I'd like to only have one profile for 316 and 316L.

Thoughts?

(I'll share my results once the wire gets here.)

We really need 16 profiles (or user configurable)!

Also, great feature suggestion on the percent-based preheat, Jaquith.

Being honest, I don't know, and as I mentioned before .. there are several different alloy mixes for SS316L, SS317L, SS304, etc all of which are SAE standards and China follows primarily GB standards; close not exact. Therefore, purchasing eg UD SS wire from China of some other than actual 'SS316L' or 'SS317L' is the reason I'm constantly modifying the CSV files. Conversion - http://www.iron-foundry.com/stainless-steel-grades.html

To date, the only Steam Engine CSV file that worked 'out of the box' was their Titanium Grade 1. 

So will it matter .. chances are yes. I certainly would run the cotton test before finalizing any build with NEW wire! My opinion, I really doubt SS wire will be anything more than a 'fad' and I feel Titanium or some alloy of Titanium with a middle of the row TCR is going to be it for TC or at least the current approach of (Resistance, Temperature) TC.

Now I've considered Platinum wire, it's a noble metal, it won't oxidize, and it has a high meting point similar to Titanium. HOWEVER, it's DAMN expensive! LOL people complain about the cost of Titanium. 

BTW .. by far Titanium is way better in every way over SS, I'm just messing around with SS out of curiosity and fun.

Thanks, Jaquith.

In the SS family, it seems 304 may have a slightly better chance at success. I'll likely pick up a spool.

Ni200 is working so well for me, using other wire is more a scientific curiosity.

When I go back to Kanthal A1, I can taste that iron. It's not an unpleasant taste, but Ni200 is nearly tasteless once broken in (a slight fishy odor if dry burned and new).

I just built and tried a Titanium/Kanthal Clapton build for the first time since I've been vaping strictly titanium and/or SS for weeks. I thought it tasted a little funny and wondered if it just needed to be broken in. Might it be that iron that I taste??

what I have found on my Vaporshark DNA 200 with the above SS wire profiles - it never enters TC mode if I use Celsius in my profile - took me a while to figure that out - not sure what the reason is - I then calculated my desired temp C into F and it always ramps up in TC mode ... not sure if this is a bug or intended - as the CSV is based on F

Using both Celsius and Fahrenheit right now, and it works for me. I'm using the latest Escribe and Firmware.

well I use 2015-10-21 EScribe 1.0.35.2 and firmware 2015-09-30 - which I believe is the latest available and I can observe this "glitch" on my device ...

My Vapor Shark is a 9/19/2015 imprinted device, I waited because of the finish issues to be sorted out. Wow that's unfortunate, but Vapor Shark is a very good company; contact them for an RMA.

It might be worth a check and device reboot and if necessary reinstall the firmware. I've tried both 480° F and 250° C on two different Atty's a single and dual and they vaped identical.

Well mine is a 9/30/2015 so I assume even newer ... Well I'll go ahead and do some more testing but I can replicate with my vortice easily - dual could build 7 wraps totalling at 0.27ohm ... Firing it at 50watts @410F it goes into TC, do I set it to 210C it just fires in wattage mode ...

Jaquith, what do you think of 430 SS? It's resistivity seems to be much higher than 316 and 304. Might this translate to a more reliable and accurate temp control?

SS430 should be 'more accurate' looking at the differences between 400F~800F, but I haven't a clue about its oxidation, leaching, etc characteristics. SS430 Fe, <0.12% C, 16-18% Cr, <0.75% Ni, <1.0% Mn, <1.0% Si, <0.040% P, <0.030% S

Being straight up, I want to avoid Cr, Ni, Al, etc long-term. However, it's certainly a wire to play with in TC. I'm just having a hard time rationalizing Platinum wire because of its price. SS alloys in contrast appeal is it's cheap. Keep in mind, a Titanium coil will outlast the Atty itself... So price!?

I just can't get over the flavor difference with SS vs titanium. I just built a Ti1/KA1 clapton dual coil and it just tastes...funny.

I only asked about SS430 because it's popular on that Unkamen site that everybody talks about. Also (and this I don't understand) on the site it lists its 430 as "nickel-free". Doesn't all SS have nickel in it?? It wouldn't be SS430 anymore without I would think.
