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:For those metal experts out there, steel or stainless steel.?
Stainless Steel is an allow of Chrome and Steel and several other additives. There are at least 100 types of Stainless.. Most common is 300 Series , that the cheapest and used in household stuff. Then there is the 400 series in that series is a stainless that can be heat treated because it contains sufficient carbon to do so. I would say if its wear you are looking for Stainless is not wear resistant to the extent other steels are. You want a heat treatable oil hardenting steel for that purpose. A good example and an old reliable one is what is called O-1 or oil hardening one. It can be heated with a torch at the wear end and quenched in oil right on the fab site. to a hardness of Rockwell C of about 55 or so and wears well. I suppose the best basket would be a 300 Series stainless to reduce rusting with end pieces that are probably bolted on made of O-1 heat treated to RC of about 55 or so. Of course if you make the wear ends removable with bolts, you can really get some wear steels for those wear parts You can use High Speed Steel RC=95, Drills are high speed steel. and even a material called Hasteloy next to carbide in hardeness. I suspect those baskets are made of Stainless Steel with wear ends of another material as ive discussed above.
Q:Steel Case V.S. Brass Case ammo?
Depends what your gun is. I wouldn't shoot steel through a 5,000 dollar gun but my SKS jams up with anything except steel ammo. It adds wear to some guns but in most cases you won't shoot enough to cause any real problems. They also make steel that is coated in lacquer that protects your gun a little. In most cases steel is no big deal, in high performance weapons I would say no.
Q:Better Movie: Man of Steel or Captain America; The First Avenger?
Captain America
Q:What oil to use on knife steel?
If the knife is stainless steel, then you don't have to worry about it rusting, unless you leave it sheathed in a wet sheath. Be sure you clean it off before folding it up or re- sheathing it. For carbon steel blades, almost any good household oil will work. 3 in 1, Rem oil, etc.
Q:Can a fine grit whetstone replace a honing steel?
A steel is to clean off an edge and remove any bends on the bevel, it is not directly for sharpening as it removes no material from the knife (or should not). A whetstone, however fine, does remove material. A steel to maintain an edge, a stone to restore an edge. They are different items for different purposes.
Q:Steel pipe info please...?
www.okorder.com
Q:Aluminum and Steel brittle or ductile based on these results?
Only steel(of this pair)might be liable to brittle fracture,which would be implied by almost zero elongation or reduction in area at fracture.On this basis the steel has not failed by brittle fracture.I would expect much more elongation in pure aluminium than your sample shows so I presume it to be brittle unless it is an alloy rather than commercially pure aluminium.However brittle fracture in metals is a particular phenomenon to be determined by impact tests and examination of fracture surfaces and is particularly relevant to metals with the body centred crystal structure.
Q:Is carbon steel a type of alloy?
Carbon steel, or plain-carbon steel, is a metal alloy. It is a combination of two elements, iron and carbon. Depending upon the amount of presence of carbon in the alloy, Carbon steel can be classified into 4 different categories- Low Carbon Steel Medium Carbon Steel High Carbon Steel Very High Carbon Steel
Q:Steel Buildings.........!?
Arch steel buildings are extremely easy to put up as compared to other conventional structures you don't need any type of heavy equipment to erect your steel arch buildings. Most of the people put their steel buildings up with the help of family or friends in just a couple of days.
Q:what imperfections or problems arise with casting steel?
Cast steel uses specific alloys of steel designed to improve the casting process. It has a specific strength and toughness range based on the alloying ingredients. It physical properties are a bit different from rolled steel. The primary problems with casting steel are porosity and voids or spaces where the mold is not completely filled with molten steel. These do not effect the basic strength of the steel but they can degrade the ability of the casting to function as designed.
