hello.. just a silly question from newbie here.. can I build a single coil with SS316L 28 Awg on mech/squonk mod?

Yep.
I still use 28ga Kanthal on my Origen Little 16 squonk RDAs. A 5-6 wrap Kanthal coil comes to about an ohm. The same coil in stainless steel will be about .5-ohms.

Is it safe? Because 28g kinda thin wire don’t you think? And stainless steel have much lower resistant.
Like I said - a SS coil with 6 wraps at 2.5mm diameter will be around .5-ohms. Not sure what you will be using it on, but if your mod and batteries are up to it, it should be fine. If you aren't sure, you need to read up on Ohm's Law and battery safety.
A .5-ohm stainless steel coil at 4.2v will pull 8.4a, (on a mechanical mod) which is not a lot, but you need to know the safe current limit of your batteries.
I use 28ga Kanthal all the time on some of my Reo Grands and it is perfectly safe, but Kanthal is about twice the resistance of stainless steel.
If you are using a regulated mod, you will be fine.

Hi and welcome,
Safe? Depending on the battery you are using, maybe yes, maybe no.
Why is 28 too thin?
Have you played with Coil wrapping | Steam Engine | free vaping calculators
How are you checking the resistance on your builds?
What atomizer are you building upon?
Cheers

Just re-read your original post and see that you are using a mechanical squonk mod. So that means you need to understand this from my previous post:

28ga wire is perfectly safe to vape even if it is thin. I'm vaping two Reo Grands with 28ga Kanthal as I type this. I only use the 28ga wire in my Origen Little clones as they are very small attys - I can fit the small coils and the vape is not too hot.

28 gauge has always worked perfectly well for me. Depending on your coil diameter and whether you want spaced wraps or not, you may want a slightly higher gauge wire, but I don't think it's strictly necessary. Use steam-engine to calculate out how many wraps it will be, and if it seems like too much metal for your build, you can certainly use a different gauge (or type) of wire. The main thing is making sure that you are building at a safe limit for your batteries. Do you have a target in mind?

One last note:
Many of the old clearomizer coils (like Kanger Protank) back in the day were wrapped with 28 or 30ga wire. So "thin" wire has been used safely for a looooong time.
Your main concern should be your batteries. They need to be rated properly for the coil resistance you plan to use.

Yes, the batteries are the most important thing, but he also has to be able to build the right coil for his target wattage range, so I'd say they are both equally important. He could have the best battery for his mech, and still over- or under-shoot target resistance and things could get unpleasant.
Knowing what to build for your battery is very important, and I am assuming you have looked at your battery situation and checked whether your build will be safe with your battery? If that is not the case, checking out some posts on Ohm's law and Mooch's blog should help you out.
Best of luck,

Let’s say I’m using a Ijoy 20700 battery for my Vandy Vape Pulse BF squonk mode, and had my Hadaly Rda with a 0.5 ohm build on it, does it mean it is safe to vape? And how safe a batteries is in term of ‘safe’?
I can't remember what Mooch said specifically about those battery specs when tested (these are new batteries) but I'm sure it's on his blog. Okay, I found it: iJoy 40A 3000mAh 20700 Bench Test Results...overrated but a good 30A battery
So, your battery is overrated I would use Mooch's figures when calculating a safe resistance. There aren't any Sony/Sanyo/LG offerings of this battery type as yet, so understand that what you have is overrated as far as capacity.

As Anna pointed out, those Ijoy batteries are rated as 40a but really capable of only 30a when tested.
So, if you are using a .5-ohm coil with the Ijoy battery, you will be pulling 8.4a at full charge (4.2v), and you are well below that safe limit of the battery.
Short answer: That Ijoy battery is safe with a .5-ohm coil.

Thanks! For conclusion.. V/R=I, 4.2/0.5=8.4a. Ijoy battery is 30a. Which means 8.4<30 it is far beyond safe limit right?
But one more thing that I don’t understand is.. The battery when fully charged will be at 4.2V right? It needs to be charge when it reaches 3.6V, am I correct? And the question is.. what does it means? Does it mean battery power? Or capacity? Or something else? What happened if I charge above 4.2V and use it to fire my mechanical mod? And what happened when i still use it below 3.6V?
Overcharging a battery is not safe and will damage the battery. Chargers are designed not to do that.
Yes. The Ijoy battery can safely deliver 30a, so if you are using a .5-ohm coil and pulling 8.4a you are well below the safe limit. Looking at your formula, you are using Ohm's Law correctly.
A good battery charger should not charge your battery above 4.2v. The only way to know for sure is to check your battery with a voltmeter immediately after charging. A few millivolts is OK, 4.23v for example, and that won't be enough to make your coil unsafe.
As you use your mech mod and the battery discharges the current draw will decrease, along with the amount of vapor. At 4.2v you will have approximately 35 watts with your .5-ohm coil, but at 3.6v the current will only be 7.2a, and the wattage goes down to around 26 watts.
