Product Description:

1.Structure of Hot-Dip Galvanized Steel Sheets in Coils JIS Description:

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering.

2.Main Features of the Hot-Dip Galvanized Steel Sheets in Coils JIS

• Excellent process capability

• Smooth and flat surface

• Workability, durability

• Excellent anticorrosive property

Q:Will painted steel rust?
If the steel is properly prepped when painted, then it would last a long time before any rust or corrosion sets in. This still all depends if the item is subjected to water or salt and if the item you painted is not scratched in any way, once exposed from the paint, the rust will begin rapidly. As far as aluminum, no it will not rust, but you do get aluminum oxidation. It gets a white flakey appearance when it begins to oxidize. Now if you are thinking of painting the rims on a car, i recommend scuffing the rim, priming it, lightly sanding and then paint to the color of choice and for the final touch apply a clear coat on the rims to help avoid the rusting. Use a paint such as rustoleum to prolong the effects of rust settling in. good luck..... good luck.....
Q:What is the difference between weldable steel and plate steel?
'Plate' does not refer to a specific alloy. It simply describes the shape in which the metal is sold. Various steel alloys have varying degrees of weldability. Some weld well, with good strength. Others weld poorly, and crack or become very weak. Try looking up information on the specific alloy of steel.
Q:How to play Broken steel in Fallout 3?
Broken Steel's quests activate once you have beaten the final mission in the purifier. If you have already beaten the game, then you should just go back to the purifier and beat it again, since normally you wouldn't be able to continue to play the game once you have beaten it without Broken Steel. If you were able to continue playing the game, then it's likely that whatever mod you used is interacting with the game and making it impossible for Broken Steel to activate.
Q:melting point of 1008 steel?
It is still the same for 1008 steel. Go to the bottom and see the listing of the grades it covers. Since the only difference between the 1006 and 1008 steel is a few micro amounts of alloys and by far the greatest majority or main component is iron (99%), as a general melt temperature , 2750 F is the melt temperature at which the other alloys are added to the charge to fine tune the mix. Just like adding salt to distilled water actually lowers the boiling point of water, adding alloys to iron decreases the melting point of iron. The iron melts at 2800F, but once alloys to make the 1008 grade are added, it decreases melt temp to 2750F. Since the melting point of pure iron is 2800F, the temperature is actually decreased by adding these impurities of alloys. These alloys are tested while the mix is starting to come down from a pure melt, steel is sampled. and then alloys below are checked and added to make the 1008 steel. The steel is maintained at 2750 F so that the less volatile alloys don't boil off before combining with steel. Minimum Properties Ultimate Tensile Strength, psi 43,900 - 51,900 Yield Strength, psi 26,100 - 34,800 Elongation 42 - 48% Chemistry Iron (Fe) 99% Carbon (C) 0.08% Manganese (Mn) 0.6% max Phosphorus (P) 0.035% max Copper (Cu) 0.2% min Sulfur (S) 0.04%
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
As far as I know, the galvanized rolls of WISCO are wider in width than other domestic steel mills, and can produce 2080 wide steel coils.
Q:How difficult is it to harden steel?
Some steel won't 'harden' very much to begin with. Mild steel found commonly around the shop/farm/house has few alloys other than carbon, and may not get the desired hardness no matter what you do. A quick test to see what type you have (mild steel vs. alloy) is to touch it to a grinding wheel.
Q:Steel reinforced armor.?
I don't think that would work. First off, there's not enough carbon in steel - even very high carbon steels are only about 2% carbon. Second, the iron atoms in steel form a crystal lattice, in the shape of a cube, with another iron atom in the middle of the cube. Each cube is about 0.3 nm per side. Carbon atoms work their way into the crystals and displace the iron atoms. But a carbon nanotube is around 1 nanometer in diameter - that's 3 times as big as the iron lattice! So a nanotube wouldn't fit. One thing you might do, however, is make a composite - mix the materials together on a scale a little bigger than the atomic scale that the iron and carbon mix to make steel. Just like a carbon fiber bicycle frame or ski pole is strands of carbon (much bigger and not as strong as nanotubes) held together with epoxy, you could hold nanotube strands together with metal. Not sure it would be good for armor, but if you can figure out a way to do it, I'm sure someone will come up with a use for it!
Q:What type of steel is most bullet resistant?
The trauma plates in most vests are made from titanium steel. But the real issue is how thick a plate of a particular material must be to soak up the kinetic energy of a particular bullet. Certain bullets are a lot easier to stop than others. But, again, it's all about the bullet mass and velocity. Bulletproof glass is usually several layers of glass bonded together with a clear plastic film and it's generally special made. Doug
Q:Steel Price .........!!?
depends what u want..
Q:what is best cookware? stainless steel or iron?
I have a combination of them both. I have Le Creuset enameled cast iron dutch-ovens, pots and pans; as well as All Clad stainless steel saute and deep-rimmed pans which have a copper core. I have one non-stick pan that I use for cooking eggs in.
