I don't know if it's flammable. Tungsten is what was used in incandescent light-bulbs forever -- that little filament that glows is made of tungsten. It has the highest melting point of all pure metals.
The problem with it is it has a super low resistivity, even lower than nickel irrc. This makes it not feasible for building unless you use like 32 or 34 gauge wire with a sh*tload of wraps, or if you use it inside of a heating element where there's plenty of surface area for the wire (as is done in the Altus).
Ok, so I decided to do a Ti coil in my DNA40 squonker recently & I like how clean it is so I wanted to switch my other atty to Ti but it's a dual coil build instead of single. I have 26 & 24awg but figured 28awg would be perfect for a dual build netting around .20 but before I buy more Ti I figured I'd start researching these threads & I see more SS mentioned. Before I buy more Ti should I consider SS as an option? How does the DNA40 perform with SS vs Ti? Any insight for us bottom feeders?
SS on dna 40 will perform great in regular wattage mode BUT will not work for temp control as SS's TCR is too small and the dna40 is set of for ni200's TCR only.Ok, so I decided to do a Ti coil in my DNA40 squonker recently & I like how clean it is so I wanted to switch my other atty to Ti but it's a dual coil build instead of single.

If you read through this thread, I think you'll find, while Ti can perform reasonably well on an Ni200 mod, SS requires at least a discrete Ti mode to perform well. I think many will also tell you of their endless struggles. With the cost of some of the new mods, especially with sales, I would suggest picking up a new mod should you wish to use SS in TC. For example, I paid $35 for the eVic VTC Mini Kit on sale.
The Evic VTC is a great chip from all accounts but there is only one mfr putting it into a squonker at the moment so I'll have to hold off but thank you for the suggestion.
correct, if they have SS on a dna 40 they're running the coil or coils in reg wattage mode no TC. one nice þing about SS is that you CAN dry burn it, pulse it, whatever you want to call it, without any negative side effects. one type of wire u might want to look into is 'nife'. zivipf is where i got mine from (i got 24-26 gauge nife48(52)). they're out of germany. you run the wire in TC or reg wattage AND it works on a dna 40 because of it's medium range TCR. there will be a temp offset with nife wire on a dna40 same as Ti. about a 100° diff.So then from those using SS on the DNA40 squonkers they weren't in TC mode? It was never really mentioned so I unfortunately assumed, gotcha. Ti it is then, I just wasn't looking forward to pulsing two coils under low wattage in a dark room. Two contact coils to get perfect in the dark doesn't sound fun but I'll go that route if that's what I gotta do, thanks!
On a VTC Mini I try to use the M1 feature with SS316L but unsure if this is even working right? Set to 92 and goes right into temp protection. Works just fine in the SS316L mode though. Any body experienced the same? (26G 6wraps @ .2ohms 2.4mm)

Funny because it works. I have it at 380º at 35W. So why do we need to (TCR 92) as said in the charts for SS316L? Is it the higher the number (92-600)= the hotter it gets?Try setting the tcr for 120.
do you own the dna200 or the dna 40? if you own the 200 u can input a custom TCR value for various types of wire. you're stuck with ni200 on the dna40.Can somebody give me the rundown of this new TCR M modes? Coming from Vapor Shark, they don't have this extra stainless steel feature.
I have a rDNA40 that I got for $190 last year sometime but now I just picked up a VTC Mini 75 for $40 because it has the features to run stainless steel and puts out more than 40W. Just needing to know what all these numbers are for so I can adjust accordingly. (90-600) apparently it's not degrees.do you own the dna200 or the dna 40? if you own the 200 u can input a custom TCR value for various types of wire. you're stuck with ni200 on the dna40.

the tcr is Temperature Coefficient of Resistance and is used for different heating elements in our attys ie - ti, ss, ni, nife......each wire has it's own tcr value which tells the board inside the mod certain parameters for said wires. i do not own a vtc mini so i can't tell you how to adj the tcr value but if you post your question here in this thread....... eVic-VT mini?I have a rDNA40 that I got for $190 last year sometime but now I just picked up a VTC Mini 75 for $40 because it has the features to run stainless steel and puts out more than 40W.

Ok thanks. So I set the number "92" for SS316L but it goes right into TP at 380° using 40W. Do I go lower to 90 or higher? How do these so called "values" operate?M1, M2 and M3 are just tcr memories. Turn off the mod with 5 clicks of fire button....press and hold fire button and up button. Pick whichever tcr memory you want to set. It can be any tcr value for any tc wire. I have mine set M1 for Ti, M2 for NiFe and M3 for 316L SS. Once you have the tcr values stored in the 3 memory positions you can select them in VTmode.
