why does steel rust?????????????
- Oxygen in the air reacts to Iron particles in steel to form Iron Oxide (commonly known as rust).s
steel or aluminum horse trailer?
- We have an aluminum trailer over a steel frame. We used to have a steel trailer. There are two differences I see are the weight and how quickly they deteriorate. I personally prefer the aluminum over the steel, the upkeep is easier and they don't weigh as much which equates to fuel savings. Also if you have a lighter truck an aluminum trailer makes the wear and tear a little easier. You can also look at the size of the truck you are going to tow the trailer with, and the size of the horses inside. All together you definately don't want to exceed the weight limits of the truck. Hope this helps...s
what are some advantages of stainless steel?
- 313 times as resistant to rust and corrosion as mild steel. 30% stronger and more durable than mild steel. 15% more conductive than mild steel. Easily wiped clean. Scratches can be easily polished out.s
Why aren't bullets made of steel?
- As others have mentioned, steel lacks the ductility to conform to rifling and seal the bore. Cannon projectiles, which usually are made of steel, overcome this problem by using one or more driving bands of softer metal, usually brass or bronze, but sometimes even plastic, on the circumference of the projectile, usually close to the base. The body of the projectile rides on the lands, while the driving band fills the grooves, seals the bore and imparts the stabilizing spin to the projectile.s

Why do we galvanise steel?
- The coating of zinc inhibits rust. First of all the zinc does not oxidize a readily as iron (steel). If the zinc coating gets scratched it still protects the exposed iron. When the zinc and exposed iron get wet they behave like a battery. Electrons flow from the zinc layer to the iron layer. The extra electrons in the iron layer replace any that might be lost to oxidation and help keep the iron metallic. Of course now the zinc oxidizes faster so eventually all of the metallic zinc is removed and the iron is unprotected and will rust. The fact that the zinc doesn't have to cover the steel is shown in another process. To protect the steel hulls of ocean going ships a block of zinc is attached to the bottom. The electrical circuit behaves as described above. When the zinc block has dissolved they just attach another one. If they keep this up the hull of the ship remains corrosion free. A tin coating on steel (as in a tin can) works just the opposite. When the tin is scratched the electrons flow from iron to tin so the iron rusts faster than it would have with no tin.s
Steel sheet vs paper?
- In okorder.com/... 11.7x8.3 inch paper 97.11 square inches 0.062651488 sq meters at 4.5gm is a non-standard 19 pound bond ledger paper, but that is OK, because at least it is in range. 38 gauge steel sheets are about the thinnest that hold their structure 0.00625 thick 1221 g/m² or, at 11.7x8.3 76.5grams So, with this data at hand we can better visualize the situation. Paper of 0.00625 thick in the size shown is 35# paper 131.68 g/m² 8.25grams Steel is higher in density than paper, so you cannot get the same size and air flow without it being lighter in weight than the steel and the air resistance would be lower for the heavier item, so steel of the same shape and thickness as paper falls faster. Suppose you want paper heavier than steel for the same area, then the thickness increases. Will a steel sheet 0.00625 thick and 11.7x8.3 inch size 76.5gm fall faster or slower than a 9 or 10 times thicker paper sheet? If it was able to hold flat in each type the thicker paper should get more backflow behind it aerodynamically and fall faster than an equal weight thinner steel sheet as my guess, but I don't have those numbers. The steel will always be heavier than the paper for the same exact shape and thickness by about 9x. My answer here is difficult, but the question has some flaws to think about.s
