What are the uses of steel plates? Professionalمنذ 3 أشهر - Automobiles - Mazouna - 61 الآراء
Nichrome is a common material for pre-wrapped RDA coils, but you won't see it often in the world of sub-ohm tanks. When you're shopping for sub-ohm tank coils, kanthal and stainless steel are the materials you're most likely to see. Compared to kanthal, stainless steel has a slightly lower resistance and a slightly faster ramp-up time for a given wire gauge. Unlike some of the other non-kanthal coil materials, people generally find that stainless steel doesn't introduce any off flavors that require getting used to.
Stainless steel also has the benefit of being an easy material to work with from a tooling standpoint. You can stamp stainless steel into shapes that wouldn't be possible to create with kanthal. In the mid-2010s – before mesh coils became the standard for cloud chasing – manufacturers were experimenting with unusual coils such as “notch coils,” which were cylinders with notches cut out of them. Shapes like that would only be possible with stainless steel.
One of the most interesting features of stainless-steel coils is that they're the only vape coils that you can use for either wattage-based or temperature control vaping. For temperature control, all that you need is a vaping device that supports stainless-steel coils – which almost all mods built in the last few years do – or allows you to enter a custom TCR.
Compared to the other two coil materials used for temperature control vaping – nickel and titanium – stainless steel has a significantly lower TCR. That means the material's change in resistance as it's heated is not as easy to measure. Some vape mods may not be completely accurate when estimating the temperature of a stainless-steel coil.
The last thing to consider before you buy a vape tank using stainless-steel coils is that stainless steel does contain a small amount of nickel. If you are allergic to nickel, you'll probably want to avoid stainless steel and stick with kanthal coils.
