RDA Rust on my RDA turning my entire cotton red (see pic )

[littlejan]

Moisture, metal, rust, who would have imagined such a thing?
I try to run an rda as dry as possible before putting it away for the day.
If I'm not planning on using it for more than a day, I pull the wick and dry burn it.

I respect that, but I'm waaaaaaaay to lazy to do that haha

Dose anybody know the trick to cutting stainless with a torch?

Plasma cutter is nice.

If I am not going to use a tank for more than a day I do not use it for more than a day. I have a strawberry filled one I had not used for 2 weeks, just picked it up and tootled it for a while. All is good in the world.

Heck you can get a plasma cutter for what some spend on 2 Reo's.

 

[Thrasher]

If ya dont have plasma ya just burn a sloppy cut and sand it down. Old school style.

Harbor freight has a couple plasma

No with a torch If you take a piece of carbon steel and clamp it to SS cut threw the carbon first the oxidation will carry right on threw the stainless.
If you use a guide and make a nice smooth cut you can grind way the transfer easily also. You may not always have access in the field to a plasma.

I've got a lot of experience working with 1/2" stuff...

sulks away kicking dirt and muttering cuss words

better save those if you roll your car and get trapped floorboard goodies become roof top life saving nutrition!

That's both disgusting, and hilarious at the same time

Sure buddy its all fun and games till a wrecked person starves to death!

Yeah... And that is where the Problem is.

If there Isn't a Recognized Standard for How Much Chromium is in an Alloy to call it "Stainless Steel", then calling something "Stainless" isn't all that Meaningful.

If you look on the back of a Fork and it says "18-8 Stainless", Cool. The fork should have 18% Chromium and 8% Nickel. Good Stuff for Corrosion Resistance.

But if an RDA says it is made from "Stainless", they are not Telling you Much. It could be High Chromium alloy. Or it could be a Junk Alloy that someone made while Looking at a Picture of Chromium.

[emoji33] some clones might use stainfull steel

Hey I make Mistakes. And 400 Stainless is Better than a Non-Chromium Steel.

But it is Not the Best Choice for "Rust" Resistance.

There is no steel best for everything. The same true for atties.

True. 440C has no Nickel in it.

But it Does have Manganese and Silicon which help in Toughness while Reducing Brittleness. And it has Molybdenum which inhibits Grain Growth while Also helping with Toughness.

400 series Steels are not the Greatest Choice for "Rust" Resistance. In fact, they are on the Low end of the Scale. And not the Greats choice for a Knife Blade either.

Cannot agree here. 440 is a great choice for surgical (and other) blades, it is even called "surgical steel". High carbon helps it to be a good martensitic steel.

Do I see a fellow metallurgist here?
I've been a metallurgist for more than 10 years (research, manufacture, failure analysis), but now I am in a biomedical field (life can make surprises...)

its rust...

for example Iron oxide = rust
since nic and juice oxidizes
ergo juice/nic oxide = rust

torch, plazma???? thats old world tech.... 3000W CO2 Lasers... thats where its at now
