Brief introduction:

Galvanized steel coils are produced through a process of metal coating which involves passing cold rolled coils through a zinc pot. The process ensures the adherence of zinc to the surface of steel sheet. The zinc layer provides excellent corrosion resistance so that it can prolong the service life of the product..

Hot dipped galvanized products are widely used in roofing, household appliance, container manufacturing, base material for pre-painting, ducting(pipe) and other construction related appliance.


Color coating steel coils are produced by cold rolled GI steel which is coated with a layer of oil pait.After painted, the coils has beautiful appearance and more durable.

Q:Is steel in spacecraft Ulysses?
Steel might have been used in some bolts sure. But.....are you under the impression that Ulysses was ever intended to crash into the Sun or something? You know it wasn't right? It was launched (in the 1980's) to study the Sun. But....uh.....not by crashing into it. Ulysses was even sent out to use Jupiter as a gravitational assist. We are closer to the Sun than Ulysses is..... Even if it did go crash into the Sun though there is absolutely no way that ANY material, natural or manmade, could survive intact all the way to the core of a star. It takes photons of LIGHT something like 100,000 years just to make it out from the core of the Sun to the surface because it is so dense. How do you propose a metal probe making it back the other way? Would it have worse effects than what? The effects, no matter what it was made out of, would be that as it got CLOSE to the Sun it would vaporize. No matter what it was made out of though it would have no affect whatsoever on the Sun. Every single element, without exception, that exists on the Earth and everywhere else in our solar system also exists in the Sun already, in far greater quantities. The planets and Sun all formed out of the same nebula at the same time. The Sun just got massive enough that fusion began and it became a star. There is already more iron in the Sun than there is everything on Earth. If you took every single atom of every element there is on the Earth it would still not add up to even a fraction of the total amount of iron in the Sun.
Q:how does steel become stainless?
a little clarification. steel doesn't become stainless. There are many different types of steel, which is an alloy of iron and other element. The other elements determine things like hardness, corrosion resistance, etc. One element is chromium, which when added in the correct proportions, forms stainless steel. PS, there are many many different stainless steels, with different proportions.
Q:What is better carbon steel or stainless steel for a knife?
carbon steel is my choice. googlecarbon steel vs stainless steel knives for more info. If you buy stainless make sure it is an alloy that will hold an edge..many a shiny knife is just a dull dud. Carbon blades don't rust unless they are left laying in the wet. I was having this conversation with a Friend once. So I took his knife and struck his knifes edge against mine with a light blow.. His had a 1/16 dent in it, mine not even a mark on it. I assume this is not a kitchen knife.

Q:Damascus steel sword blades question,?
Actualy, the secrets of forging Damascus steel has been rediscovered. In the 1970s, a Russian scientist found that he could duplicate the steel found in old Damascene swords. While it is true that such swords (which have to be made by hand) would be more expensive than usual, you must keep in mind that the majority of Damascus swords are still forged in Damascus. Syria is a highly inexpensive country, and the price of a Damascus blade, while being expensive to Syrians, would be cheap to Westerners. In reference to your question about wether there is anything special about Damascus steel, the answer is yes. At the time of its creation, Damascus steel was the lightest and most flexiable metal known to man, even lighter than the steel Katana swords used by the Samurai of Japan. During the Crusades, Europeans reported that the Arab blades were capable of bending in the wind, and floating on water. While these are certainly exaggerations, they are proof that Damascus blades were far lighter and stronger than the crude iron weapons used by the Crusaders.
Q:How to wear out stainless steel?
Just abuse it. You could hit with a hammer, expose it to flame, throw it at or grind it around on rocks or concrete, rub it with steel wool. (be artful in how you do this, the pattern could end up looking too deliberate if you're not careful.) For an example of naturally aged stainless steel, look at some cooking pots/pans. If you don't have any old ones, maybe your parents or someone you know does. They usually get a little banged up/scuffed/stained after a while. (I think the stainless just means it doesn't rust.)
Q:Where can I find an atomic structure of carbon steel?
Carbon steel is a polycrystalline substance containing several compounds. Most of it is iron, but there are crystals of austenite and martensite present, plus other iron carbides. Each of these has a different atomic structure. The properties of the steel depend not so much on the atomic structures of the compounds, but more on the size and abundance of the crystals. The function of these crystals is to impede the movements of dislocations through the iron.
Q:whats the average price of wide flange steel W10x30?
The price of steel is increasing daily, so an exact answer is rough. A W10x30 is a fairly common shape and shouldn't be too hard to find. For a very rough ballpark number, say $700/ton (installed price), the piece you require should be in the range of about $250.00 or less as I assume you'll be doing the installing. Please don't take this as the gospel, however. Price varies on location, stock, and availability. Open the phone book and contact your local steel supplier. Because the piece you require is fairly short, you might get lucky and find someone who has a waste piece that length that they will give you a good deal on. --------------------------------------... I just checked the AISC web site to verify the number I quoted above and they posted an article stating that the average mill price had just increased to over $1000/ton in May. The best advice I can provide at this point is to buy the W10 now and don't wait any longer.
Q:steel refining process?
As Mr. Perfessor says, refining raw steel involves a lot of purifications of the raw steel; and to expand a bit, these refining processes also add corrosion-resistances to certain graded steels, and durability factors, when heat-tempering processes are used. All of these refining processes, and coating processes help steel products last when exposed to moistures, salts, and other corrosive conditions that steel can be exposed to, whether the steel is in open-air/water/space, embedded in concretes and other masonry products, or part of a protective barrier system in power plants, engines, etc. Hope this also helps; the eggster.
Q:Should I keep my steel cents as an investment?
The steel in steel cents is the same as the steel in soup cans you throw out all the time. There is no sense in holding steel cents for their value as scrap. There are way too many steel cents around for them to ever have much numismatic value.
