Description of Prepainted Rolled steel Coil for Construction Roofing
Prepainted Rolled steel Coil 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 Prepainted Rolled steel Coil for Construction Roofing

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:types of steel.......?
Don't know too much but I know combat grade katanas are made out of folded carbon-steel. Could also look into industrial steel grading systems if you are looking for something to show off at a martial arts tournament or something.
Q:GUITAR! is this nylon or steel? - fingerstyle?
The young man in the video is using a steel string guitar. Steel string guitars can be played fingerstyle or with a pick. Classical guitars use nylon strings and are only played fingerstyle. Classical guitars are used almost exclusively for playing classical music. If you're not interested in playing classical music then it's the wrong guitar for you. Steel string guitars can be used for a wide range of musical styles from pop to rock to folk to bluegrass to country, and more. Don't worry about pain - your fingers will hurt at first with either nylon or steel strings but that passes quickly. Buy the guitar that's most appropriate for the music you want to play.
Q:Types of knife steel?
154cm is a very good knife steel, the problem is in the heat treating. Stainless should be cryo treated to get all it can offer. That being said, if you really want to drop some coin, look at getting one made from CPM 440V. Stainless isn't as strong as carbon but on a smaller knife works well. You might also look for D-2 Tool steel. There are factory knives that are made of that.
Q:stainless steel coating?
No, it's not possible. Quite apart from the chemistry which would prevent it occurring, the aluminium has a far greater rate of thermal expansion than stainless steel, so any coating wouldn't last.
Q:melting point of 1008 steel?
1. okorder.com 2. Input (melting point 1008 steel) as the search string 3. Check the links; the third one showed the answer in an MSDS
Q:Is 100% carbon steel baking sheet safe?
Yes. Carbon steel is one of the most common metals used by human beings. When the Bronze Age ended and the Iron Age started, most of the iron humans could make was carbon steel. A Cast Iron frying pan is carbon steel (well... technically, there are differences between cast irons and steels but... anyway). Our cast iron frying pans (almost the only fry pans we have used for 30+ years) are mostly non-stick because we keep them well seasoned. Humans need iron in our diet anyway. You might want to check to verify what (if anything) it is coated with to make it Non-stick because, in general, steel cookware is stick. If it is coated with ceramic (enameled), then there won't be any rust because the iron is coated and protected from water. The non-stick ceramic coatings are very good. Ceramics are chemically inert to almost everything on earth (all but some of the most exotic chemicals you will ever find in a Chem Lab). As a side note... a large number of studies of industrial exposure to aluminum and aluminum compounds (people who work in Al production plants and are exposed to large quantities for years and years and years) has shown that there is NO correlation with Alzheimers or any other diseases. The major health risk for these populations was lung problems due to inhalation of fine dust (which, turned out, was not even as bad as breathing, for example, dust containing cotton fibers in garment workers).
Q:How difficult is it to harden steel?
harder steel has a higher carbon and chromium content
Q:Soldering Steel Wire?
You can indeed by using the correct flux as normal soldering fluxes as used by plumbers will not work. I believe to solder steel it requires an acid flux which will corrode copper so when its done make sure its well cleaned afterwards and if possible apply a corrosion proofer afterwards ie paint or even petroleum jelly. I am curious as to why you would want to solder wire to a steel nail.

Q:im getting a sword tommoro and i need to figure out the pros and con of stainless steel and carbon steel sword?
Well generally Stainless steel blades are machine made and are of a display quality.. so expect looks, but don't expect quality or functionality from one. From carbon steel, I'd say you'd be looking at swords for practitioners of a sword art, reenactment, and collector quality blades. Stainless Steel Pros: Good for short blades like kitchen knives, cheap, won't easily rust or corrode. Cons: Long blades like swords become increasingly brittle and can snap with light use, most lack actual tangs(part of the blade that keeps the blade in the handle.) and are just welded onto a wire that[if broken} will send the blade out like a missile when swung, these are cheap display quality only. Carbon Steel Pros: Are usually much stronger and of a higher quality than their stainless counterparts, are often handmade by professional sword-smiths, no two blades are alike, fully functional work of art. Cons: Requires responsible care and maintenance, will corrode and rust easier, can be much more expensive.
