Hot-dip Zinc Coating Steel Building Roof Walls
1.Structure of Hot-Dip Galvanized Steel Sheet 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.

Q:Heat treatment of mild steel? Process description macro-micro
Alright, usually whu heat you heat treat mild steel, this is because you would like it stronger than you got it. To do this you must alter the grain structure of the part or in other words, the CRYSTALLITES. Ultimately you'll end up altering the nature of the grains structure changing the tensile strength it can handle, yield strength, and even change the elongation percentage that it can tolerate under load. Heat treatment controls the rate of diffusion, and the rate of cooling within the microstructure to create these elements. Usually what they use to do this is add an element to it to make it stronger such as carbon to increase its rockwell hardness, which by the way the lower you go the harder the part can become. Heat treatment can be used in more ways than this. It can also be used to weaken the parts grain structure. This will lower the parts mechanical properties making it softer and more ductile or easier to manipulate if you have to bend it into a particular shape. Typically if you allow the part to cool after heat treatment it does go through annealing. The part will be heat treated into different stages. The first being the austenitic crystal phase which depending on how hard and strong you want it, will be at its peak. When it is cooled, it will go through a will transform to martensite which is a hard yet brittle crystalline structure. Martenised part will usually be tempered to a certain degree to improve the mechanical properties to what is needed. There is more to this and you can use the link below to read more about it.
Q:Best steel for a all purpose knife?
There is no right one answer, because the term all purpose knife covers a very broad spectrum. The same knife that would be good for wood carving will not be the same for food prep, and will not be the same for general utility purposes. I'll just give you my humble opinion. For fixed blade, hard use blades. Where you will be doing bush tasks like chopping, carving etc... 1095 carbon is generally the standard. Now, 1095 is a great steel, it isn't the BEST steel. There are other steels that can outperform it. But for the price and availability its hard to beat. For folders, I prefer a decent stainless, like aus 8. It holds a good edge, and will hold up to any tasks you need a folding knife to do. Contrary to what you will read on the internet, stainless steel is not all crap. Its just that cheap stainless is just that, cheap. Stainless steel is only as good as its tempering process, some companies such as boker do amazing things with the steel and make for an impressive blade. Just stay away from crap stainless. So to sum up. 1095 for fixed blades. aus 8 for folders. These are both common steels used by different companies. If you get caught up on finding the perfect steel, you may overlook more important aspects of the knife itself. Unless your fixed blade is mostly going to be a food processing, and skinning knife, then I would suggest a QUALITY stainless as well. Remember that all high carbon blades need to be kept oiled or they will start to rust very fast. Btw, I suggest anyone looking into knives to check out mora fixed blades. Incredibly cheap, sharp and durable. They are the rockstars of bushcraft.
Q:Who or Where can I buy a Steel Pipe Making Machine?
I'll answer both those questions. Your first question is: Who can I buy a Steel Pipe Making Machine? To which I reply: anyone. I'd put great consideration on the age of the person you are giving this machine to, and perhaps their physical ability. Cripples don't work well with steel pipes. Unless you are...beating them with one. Second question is: Where can I buy a Steel Pipe Making Machine? My reply: OKorder, or Steel Pipe Makers Incorporated. You could probably just steal one out of their factories. They have billions, and the actual machines are no bigger than...a bus or two. Just pop one in your backpack on the way out. But honestly, I don't know where to get a steel pipe making machine. BUT! I do know where to get a steel pipe making machine making machine. Ask santa. (BTW: Why do you need the steel pipes? I smell conspiracy!)
Q:What are steel cut oats?
It does NOT look or cook like oatmeal but is made from the same grain. It takes much longer to cook since it is a whole grain, and tastes very good by the way. If you hate the slimy feel of oatmeal, this is the one to try, with all the same nutritional goodness of oatmeal. You can find it in most grocery stores in the hot cereal aisle. EDIT: you are right Mnt. Camp, steel cut is better that the regular oatmeal.
Q:Question about the strength of steel..?
If done correctly it should increase the tensile strength at least.
Q:How do you calculate density of the steel ball in grams per cubic centimeter?
To calculate the density of any object you will always use the formula: Density = Mass / Volume (P=M/V). You have recorded the known values of the mass and the diameter of the ball (sphere), so we have everything needed to calculate the Density. Mass is 66.80g, but we shall need to use another formula to calculate the volume of the sphere. The formula to use is 4/3 X Pi X radius cubed. However, first of all we need to turn your measurement of the diameter of the steel sphere into the radius of the steel sphere (So that it can be substituted in place of the “radius” in the above formula). Simply half the diameter to find the radius. So 2.51 cm divided by 2 is 1.255 cm. Now insert the radius 1.255cm into the above formula. It would be read like this: 4/3 X 3.14159… X 1.255 ¬cubed (OR 4/3 X 3.14159 X 1.255X1.255X1.255), = 8.2798. So, now we know that the sphere has a volume of 8.2798 cm cubed, we can use this number in place of the “V” in the density formula P=M/V, and we can also substitute in the Mass (66.80g). So now P=66.80 / 8.2798, which = 8.07g/cm cubed. Now we know that from your measurements, steel has a density of 8.07g/cm cubed! This is fairly close to the real life average density, which if I remember correctly is around 7.8 g/cm cubed. Just remember, though, that as steel is an alloy it’s density is not standard and varies due to carbon content etc. Anyway, I hope that helped you!
Q:does this density are same for all type of steel? re : 7850kg/cu.m?
90% of the steels used today are plain mild carbon steels consisting of iron with less than 1% carbon content and as such have a density of about 7750 kg/cubic meter. Some special steels which have a significant percentage of alloying elements such as chrome or manganese or other elements will have greater density bringing the steel up to about 8000 kg / cubic meter. There are a greater many factors influencing the exact density of a steel. Even for steels of exactly the same content of iron , carbon and other alloying elements, there may be a difference ( very small mind you ) in density due to work hardening. The difference in this case is due to movement of dislocations which become locked in the grain boundaries and this forms a more dense crystal structure. For this same reason, the theoretical density of steel (which does not take into account dislocations) is greater than the measured density of steel.
Q:How did the growth of the steel industry influence the development of other industries?
At least three ways: 1. Steel as a material that other industries could use to do things that couldn't be done before (for example, construction (skyscrapers, long bridges, etc.)) or could now be done at much lower cost and hence increased the size of the industry (automobiles, bearings, etc.)
Q:white gold engagement ring with stainless steel wedding band?
Stainless Steel Matching Wedding Bands
Q:Why buy recycled steel?
Where you buy all your steel. The recycled and new steel are indistinguishable from each other. You won't recognize the one from the other. Same thing with glass. A certain percentage must be used glass, to enhance the quality of the total batch. Peace.
