Q:How did the planes break the steel?
I saw a one-hour program about this on PBS a couple of years ago. The buildings were constructed with the concrete-clad steel supporting columns at the center of the buildings, with a relatively thin lattice of steel struts along the outer wall. When the planes hit, they sheered through the thin steel struts easily by sheer momentum, while, at the same time, the thin steel stripped off the wings. The bodies of the planes got as far as the supporting columns in the center of the buildings, but were stopped there. The heaviest, densest pieces, the engines, went completely through the buildings and popped out the other side. It's important to understand that even light materials can cut through metal, if the light material is going fast enough. I saw this first hand, when I was in the Navy and stationed on board ship. We had a helicopter crash on our flight deck during heavy weather. The blades were made of light, carbon-composite material, but they were going so fast that they cut through the aluminum deck. I still have photos of that damage.
Q:dangers of the steel factories?
Same as other steel plants, getting crushed by falling steel, getting burned by hot metal etc
Q:Can your sweat tarnish real silver & steel jewelry?
steel shouldn't really tarnish, it rusts and moisture increases that. Silver tarnishes when exposed to air and sulfur. Moisture increases the process a bit, but it happens anyway. Sweat is not gross, it's a necessary function of your body, otherwise you would die. A lot of sports people wear jewelry and they sweat a lot. If you wear the jewelry all the time, that will prevent the tarnish a bit. If you take it off, clean it (water and dish washing liquid), dry it and put it in a zip lock back to keep it away from air and moisture. In the end, cleaning the jewelry is quick and easy so don't worry about it.
Q: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.
Q:Why would a knife be made from surgical steel?
Surgical Steel Knife
Q:Can carbon steel be solution annealed?
No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.
Q:What are some good knife steels?
Buying good knifes now-adays is very difficult as most steel is made abroad and the quality is not the same as it used to be, British steel made in Sheffield used to rule the world but alas no more! so basically you get what you pay for, so you must be prepared to part with a substantialal amount of your hard earnt cash to get the best.
Q:ceramic vs stainless steel headers HELP!!!!!!!!!!!!!! for a 98 civic?
1) okorder.com... The top two are of 4-1 design. Good luck, have fun.
Q:What kind of drill bit will go threw steel?
it's go through steel buddy. But i would imagine that a majority of your standard bits out there will do it. I know there are material specific bits but i would say if you didn't have real expensive drill bits I would try pretty much any of them. If you are talking about the frame of your car or something that thick, then a heavy-duty would be necessary. Don't go drop a lot of money on a diamond bit unless you just keep tearing them up trying to drill through whatever it is you're trying to accomplish. Ive seen wood bits go through some heavy duty metal, so give it a try and save some money.
Q:Damascus steel knife?
Pattern welded /damascus is too expensive to use as an everyday knife, as it can cost more than silver. It's best kept as a collection piece. You'd be stupid to keep it in your pocket or use it everyday. that would be a waste of money. Knives you use everyday might be lost or stolen, or they may get rusted, worn, or dirty..... ruining their value. From that point of view the strength or edge-holding ability means very little. Specifically, the bushcraft knife is pattern welded steel. True damascus or Wootz steel is something you'll only find in museums and private collections. they stopped making it several hundred years ago. Despite what many people have claimed, Wootz damascus was inferior to modern tool steels in every respect. It was a brittle, dirty material. It's legendary status has more to do with myth and storytelling. The reason they stopped making was undoubtaby because more modern methods came along that produced a more consistent product, more quickly and easily. Old technologies tend to be abandoned for good reasons. With pattern welded steel, about a dozen strips of two different grades of steel have been stacked, welded together, the twisted and forged to create interesting patterns. This more of an artistic process and doesn't improve the properties of modern steels. Pattern welded steel is for the most part, inferior to a homogenous blade made of a single grade of steel. First of all, PW is a handmade product which means there will be faults and oxide inclusions incorporated into the steel. The welding process is not perfect. Secondly, in the hardening and tempering process you end up with a compromise between the properties of the two different grades of steel. You end up with a product that is not quite as good as either steel would have been individually. The blade may either be too brittle or too soft.
