Product 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:What is the highest quality carbon steel or cold steel a katana can be?
Types of steel are one issue. But the quality of steel no matter what type is even more important. The only way to be sure that you are getting a good blade is to buy from someone that already has a reputation for producing great blades. Stop the questions about who thinks what type of steel is best and investigate the steel blades offered by companies like Bugei Trading company. they have good blades. Opinions vary, but Bugei has proven that they make good swords. That is all that is needed to be known. Any questions you have are best directed to them, not here.
Q:What are the end uses of steel coil? galvanized steel coil?
Steel coil is the name given to thinner sheet steel when it is manufactured - it comes out of the machine and is formed into a coil for ease of handling storage and transportation. Thin sheet steel is used for plenty of stuff. It can be slit (cut) into thin strips as well as just cropped and used at one of the standard lengths x widths it leaves the mill. There is a big market for this material. It is used in many construction and engineering applications for things like ducting, boxes, gutters, down pipes, flashings, panels, car bodies etc., anything made of thin steel Galvanising is a flash coating of zinc which improves it's corrosion resitance. Cost wise it is a relatively cheap material. The chemical composition of steel varies, it is mostly iron but has various other elements added or present as impurities that change it's characteristics, depending on the end use. These additional elements can be selected to give better weld ability, hardness, tensile strength, corrosion resistance, flexibility and so on. In many applications excess of these chemicals is undesirable. For example sulphur and carbon are generally better at lower levels. The chemical composition data is contained in a material data sheet and expressed as a percentage of the chemical present and which gives the composition of a particular batch of steel, allowing it to be selected for particular applications and traced for quality assurance purposes. The list you have there shows presence and quantity of other elements in a particular batch of coil. The thickness is 0.23mm, quite thin.
Q:Steel Cage Matches: Should they end by pinfall, escape or either?
That exists.. Ts called hell in a cell. And normal cage matches are fine the way they are
Q:mild steel?
i thnk 7.85 the density of ms is 7.85 kg/cm2 and formula is density=mass/volume u have volume=1m3 7.85*1=mass so 7.85 kg
Q:Maple Story Steel Polearm?
Steel polearm was from the Aran Welcome Event, which ended a few weeks ago. Now is the worst time to buy one, since the craze just ended and steel polearms are now heavily in demand (sadly). Your best bet is the free market, but they will cost you a few mil.
Q:Can carbon steel be solution annealed?
No. Carbon steel has two different crystal structures, FCC and BCC , depending on the temperature. when you heat steel up and then quench it, it locks the crystal structure into the BCC form. this makes it hard. whereas precipitation hardened austentic stainlesses remain BCC regardless of the temp, so the hardness change is not a function of thermally induced strain. you can anneal carbon steel but the thermal profile is closer to the precipitation profile of PH stainlesses than it is to the Solution annealing profile.
Q:Can your sweat tarnish real silver & steel jewelry?
steel shouldn't really tarnish, it rusts and moisture increases that. Silver tarnishes when exposed to air and sulfur. Moisture increases the process a bit, but it happens anyway. Sweat is not gross, it's a necessary function of your body, otherwise you would die. A lot of sports people wear jewelry and they sweat a lot. If you wear the jewelry all the time, that will prevent the tarnish a bit. If you take it off, clean it (water and dish washing liquid), dry it and put it in a zip lock back to keep it away from air and moisture. In the end, cleaning the jewelry is quick and easy so don't worry about it.
Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
Q:what imperfections or problems arise with casting steel?
It contains too many air bubble spacing and too many impurity that make it easily to be broken apart. Melt it down again with high heat to remove most impurity, after this process,it becomes iron.
Q:difference between steel and fiberglass?
Steel will be heavier but easier to manufacture. There won't be a huge weight advantage because you can use steel mesh which works the same as solid, near enough, as an electromagnetic reflector. Steel can just be pressed, fiberglass has to be laid up of resin and mat and then allowed to cure. Fiberglass will also need to be coated in something conductive whereas you can just spray paint the steel, or even buy it pre-coated.
