Corrosion properties of Steel

Phant0m51 · 06-01-2003, 12:57 PM

I was wondering what the corrosion properties of mixing Steel, Copper, and Bronze parts would be. I don't know how the steel will react with the other 2. I can't seem to find the Metal Corrosion chart anywhere either.

Thanks,
Jonathan

The steel will most definetly corrode.

What kind of steel will you be using?

I'm thinking of using a 50 Gallon Steel Drum for a cooling method like BladeRunners.

I think Painting the inside of the drum should prevent any problems. Rust proofing paint should be available at any hardware store, but i don't know how well it does underwater.

Whatever they paint boats with should do the job.

That would defeat the purpose of using a steel barrel over a plastic one though. I assume he wants to use steel because it might help keep the water cool. What you should consider is using an aluminum beer kag(sp?). You may have to take extra corrosion prevention though. But maybe those already have a liner of somekind.

pretty sure Bladerunner used a stainless steel container.

The heat transfer of stainless steel is low compared to plain carbon steel (and both are quite a bit lower than aluminum, let alone copper). Much like the recent discussion on copper vs brass, the wall thickness also comes into play.

As for corrosion, obviously the nod goes to stainless steel. Painting of carbon steel isn't bad on performance as the paint thickness is normally only a few mils, but surface preparation is key to long paint life. Without sufficient prep, lingering rust spots, oils, sharp edges/burrs, etc., will all accelerate the breakdown of the paint.

One warning with stainless if you have something made yourself: If you bend stainless using a die that has been used for plain carbon steel, you'll get rust along the bend lines due to material left on the die. It's purely cosmetic and won't affect the stainless, but looks like crap. Same goes for using wire brushes that are not stainless.

since steel drums are made to carry liquid i think it's safe to say it's either stainless steel or coated with something.

I would say that depends on what is in the drums. I am sure they make different drums for different purposes. I got some 50gal drums back home and they are rusted to beat hell on the inside, but they where made to carry oil.

The reason I was asking about the steel drums is because at my work we go through about 2 drums a month, and we just cut the lids off and throw them away. The contents that we cary is 'Perkote' which is, ironically, an anti-oxitive. We put it inside of our washer's because we wash approx. 1,000,000 steel parts a week. We need to keep them from rusting. So i highly doubt the inside of the steel drum is going to be rusty.

Does anybody know if adding Perkote to a WB cooling setup would do anything? Anybody else even know what Perkote is? Heh, thanks for the replies, but I'm not going to be using the Steel drums anymore. I'm going to be making some 'drums' out of plexiglass.

I have a secret that I'm going to spill right now, but I think it's going to be an awesome idea. I'm going to be opening a business (not going to tell what kind, that'd ruin the fun of it all). But I'm going to have 35 computers in it, and I'm going to water cool all of them from a central tank (I know 50 Gal isn't going to cut it, but I have more stuff). I'm not going to use a Radiator to cool it either. I'm hoping for below ambient temperatures from a closed loop circuit.

You guys can draw your own conclusions. Thanks again for the replies, you are all veyr helpful all the time!

Pretty sure Bladerunner used a plain old steel gas 'bottle'. Same kind as the ones that hold butane for campers but bigger (usualy propane for industrial heaters and whatnot)...

Most drums hold chemicals/oils/spirits,ect, not water. Water (or other inerts) is usualy stored in PVC is'nt it?. Likewise most corrosives are stored in plastic/PVC barrels...
