SS316L Help


Lance

Recommended Posts

Hello People

New user here for the Hcigar VT200.

I have just got some SS316L 24g Wire was trying to figure out which CSV file to use?

I have at the moment uploaded to my VT200 as follows:

316, 316L Elite and the profile some one posted on here (sorry forgot the name).

When placed on the VT200 the ohms comes in at 0.29 but its crap cold vape and hits TC instant, If i keep the button pressed and get the ohms to 0.32 after some heat is generated it fires and plenty of vapour and warm.

SO should i lock the ohms? also tested the ohms on ohm metre as well and reads the same as the VT200.

I am using a Steam Crave Aromariser with the Velocity deck.

No issues with NI200 Ti01 or Kanthal but with the couple of hours testing Stainless Steel does seem to give me a denser vape and full flavour.

Thanks
Lance

You can make the TCR what ever you want. But if you put in a higher TCR than you actually have, then the temp will be higher than you think. Meaning you have 400 set, but actual it's 500F. If you do a burn test with dry cotton, you could at least see if you are in the ball park. If you are making a little visible smoke 420-470 you are in the ball park. I have to use 304 with my 316 crown coils just because the nickle legs throw it off. But if you are buying 316 wire, then it should be 316.

There are so many 'SS316L' alloy mixes, nevermind the non SAE conversions that it's difficult to use any SS316L without knowing exactly what you have. 

Here's some for UD SS316L, version 4 is a tad warmer; I'm using 1 single 24 gauge wire at appx 0.32 Ohms. The 'standard' SS316L was too cool.

When I click your v4 link it just brings me to the filedropper home page. Is there any other way I can get it?

Ok another build

SS316L 24g dual 11 wraps 2.5mm on ohms meter it comes out at 0.40, Then when i put it on the VT200 it registers 0.37 but it does fire but it hits TP and doesn't go higher than 20w and cold vape not much vapor either.

This is with a UD Bellus and Aramoriser RDTA.

So if i take the tank back off and put it back on the ohms will go up by 0.04 to 0.41 and then fires with a lovely warm vape.1

But when i leave the tank for say 10 minutes and go back to it, It has gone back to 0.37 and back to hitting TP with in a second.

Tried 4 different CSV files inc the ones from Jaquith and wire wizard.

On power only mode its perfect.

Yep i have and it works.

But in order to get it to a ohms that work its hit and miss as i have to fire it in kanthal for a split second then take the tank off and back on again and if im lucky then the ohms will have raised 0.02 to 0.03 and then lock it and it works, But am i getting the correct TC or ?

Easy enough, here's version 3.5; it's lower temps are unchanged, but the higher temps are an average of V3 and V4 .. hence V3.5 - http://www.filedropper.com/dna200-ud-ss316ldjaquithv35

In addition, V3.25 is an average of V3 and V3.5 at the higher temps - http://www.filedropper.com/dna200-ud-ss316ldjaquithv325

Let me know! BTW on SS I try to keep the preheat between 2-3; I'm using a 1.9 at 0.5 seconds with a 120% of the set wattage.

Wow. Ok, I'm uploading these profiles on my VT200 right now. So which one of these CSV files do you think will work best with the UD 316L? And by saying you try to keep the preheat between 2-3, are you talking about the punch?

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!

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 ...
