Structure of Al-Zinc coated steel coil

 Al-Zinc Coated steel Rolled coil for roofing

Description of Aluminum Zinc Rolled Coil
Aluminum zinc coils is a kind of coated steel coil/sheet. With the cold rolled steel of different strength and thickness as substrate, it is produced through applying Al-Zn coat on both faces by hot dip process. In its coating, Al accounts for about 55%, Si 1.6%, while the remaining is Zn. Aluminum zinc coils enjoys both the physical protective feature and durability of Al and the electrochemical protective property of Zn. And its surface has bright silver color and regular embossed-like figure, which are highly decorative. 

 

 Main Feature of Al-Zinc coated steel coil

1.Corrosion resistance: It mainly depends on the aluminum protection. When the zinc being worn, the aluminum will  form a dense layer of aluminum oxide, resist corrosion material to prevent further corrosion inside. 
2. Heat resistance: Aluminum zinc alloy steel sheet has excellent heat resistance, can withstand high temperatures over 300 centigrade, and is similar with aluminized steel high temperature oxidation resistance. It often used in chimney pipes, ovens, fluorescent lighting device and the device cover. 
3. Heat reflective: Galvanized steel plate heat-reflective high rate is twice as galvanized steel, often used to make insulation materials. 
4. Economy: Because density of 55% AL-Zn is smaller than the density of Zn, so in the same weight and thickness of Galvanized zinc layer, aluminum-zinc steel plate is larger area more than 3% of galvanized steel sheet.

Q:Can I soften the steel on steel toe boots?
No chance
Q:Is rail steel like other types of steel?
Steel okorder.com... If care is not taken in the method used to melt the steel that alloy will change because the carbon will burn in the process. Also part of a steels rating is a result of heat treatments used. When melted it will loose those properties. By the way rail road ties are either wood or concrete- not steel.
Q:how to make a unique piece of steel?
If you really want to do this, you should be getting some books on steel metallurgy rather than asking on Yahoo. ASM sells a Metallurgy for the non-metallurgist that would be a good introduction. Most university libraries will have the full ASM handbook that includes detailed information for different grades of steel (vol 1), heat treatment and surface hardening (vol 4), testing (vols 8-12), and casting (vol 15). A reference for continuous cooling transformation diagrams will also help in designing a heat treatment process. If you want to make something stronger than most commercial steels, you'll need to get into nanotechnology and unconventional steel processing methods like powder metallurgy. You can increase the strength of steel by about 1000% by reducing the grain size from 50 micron (typical for conventional processing methods) to 100 nm (achievable through high-energy ball milling). Though you'd also need to customize the chemistry to stabilize the grain size during the necessary thermal processing, I believe zirconium works well with iron.
Q:Aluminum vs Steel motorcycle gas tank?
Steel is most common. Aluminum is lighter but it's harder to form, so more expensive. Plus it dents more easily. And you can't use a magnetic tank bag. I've seen stainless steel tanks but they were usually specially made.
Q:What's the process of making steel?
I believe you are asking about two vastly different processes. This is science so, if you want a specific answer, you have to ask specific questions. VERY Basically... 1) Pig iron production works by melting iron and pouring it into molds that produce ingots called pigs. 2) fraction distillation separates different substances (typically starting in liquid form) by controlled heating so, since different substances boil at different temperatures, the vapors can be captured selectively.
Q:Starting a steel mill?
Typically, steel mills are worth $20 million to $200 million and are owned by large corporations. Your best bet to own one would be to take over a corporation that already has one. That way you have all the supply lines, customers, experts and other workers already there, too. Stick with investing in going concerns, so you don't need to be an expert in each business to build it up. Get them ready made, learn the details from the people already doing it, then work out ways to improve it. Do not get tempted to borrow even 10c from the scammers who have answered your question. Start saving your real money, reading the financial news, and making small real investments in real stocks.
Q:What is stainless steel 316, and what are its properties?
if you want to know details, try looking it up in wikipedia. It's not a reliable source for everything, but truly technical stuff is good. It lists the exact range of elements, heats, and other things, as well as uses and things it shouldn't be used for.
Q:What is the amount of Iron found in Steel?
Steel is almost all elemental Iron (Fe) with a small percentage of carbon (about 0.2 percent) and other alloying metals if required. Iron as in cast iron just has more carbon which lowers the melting point to where it can be cast with lower technology (it was discovered first). Bessemer developed a process to remove most of the carbon and increase the furnace heat, resulting in a tougher metal called steel.
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:So i got caught steeling?
Steeling? What's that? Did you take a piece of steel and weld it? I am confused?
