1.Structure of Hot-Dip Galvanized Steel Sheet in Coils EN 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:Why was there molten steel at Ground Zero?
that's just it: there wasn't very much molten steel for the very reason you point out. Jet fuel burns at 800° to 1500°F. This is not hot enough to melt structural steel. However, engineers say that for the World Trade Center towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength. Steel will lose about half its strength at 1,200 degrees F. The steel will also become distorted when heat is not a uniform temperature. after the collapse, a LOT of folks took a look at the remains. the result was the conclusion that the fire caused the central core of the building to weaken. When the floors collapsed one on top of the other, the weight was too much for the weaked core to bear, causing the result we are all familiar with. hope this helps
Q:Is steel in spacecraft Ulysses?
Steel might have been used in some bolts sure. But.....are you under the impression that Ulysses was ever intended to crash into the Sun or something? You know it wasn't right? It was launched (in the 1980's) to study the Sun. But....uh.....not by crashing into it. Ulysses was even sent out to use Jupiter as a gravitational assist. We are closer to the Sun than Ulysses is..... Even if it did go crash into the Sun though there is absolutely no way that ANY material, natural or manmade, could survive intact all the way to the core of a star. It takes photons of LIGHT something like 100,000 years just to make it out from the core of the Sun to the surface because it is so dense. How do you propose a metal probe making it back the other way? Would it have worse effects than what? The effects, no matter what it was made out of, would be that as it got CLOSE to the Sun it would vaporize. No matter what it was made out of though it would have no affect whatsoever on the Sun. Every single element, without exception, that exists on the Earth and everywhere else in our solar system also exists in the Sun already, in far greater quantities. The planets and Sun all formed out of the same nebula at the same time. The Sun just got massive enough that fusion began and it became a star. There is already more iron in the Sun than there is everything on Earth. If you took every single atom of every element there is on the Earth it would still not add up to even a fraction of the total amount of iron in the Sun.
Q:What is the energy used in making steel?
Making steel is very energy intensive. Mining the raw ore requires a lot of machinery that uses fuel or electricity . Transporting the ore requires a lot of fuel. Refining not only uses a lot of electricity but coal is added to change the iron ore into steel.
Q:fallout 3 before broken steel?
Yes. The Broken Steel add-on goes automatically where ever you are. The thing is, I would like stand around the control room for a little while until the Broken Steel add-on is completely downloaded (Basically pop A LOT of rad-x and radaway). You should see a pop-up message saying that Broken Steel is installed and the level cap is now at 30.
Q:Casting Stainless Steel?
You have 2 options. Sand casting or investment casting. Stainless steel can be cast with either of these methods. In either case a model or pattern will have to be created. For sand casting the pattern is all that is needed to go to casting. For investment casting the pattern is used to make a wax casting, which is then coated with the investment. The wax is burned out and the metal is then poured into the cavity. If you are making just 1 or 2 pieces you can have waxes machined. This saves the intermediate step Depending on the size machining may still be your best option. Especially if you want just 1 part.
Q:What's the difference between stainless steel and surgical steel...?
Surgical stainless steel is a variation of steel usually consisting of an alloy of chromium (12–20%), molybdenum (0.2–3%), and sometimes nickel (8–12%). The chromium gives the metal its scratch-resistance and corrosion resistance. The nickel provides a smooth and polished finish. The molybdenum gives greater hardness, and helps maintaining a cutting edge. In metallurgy, stainless steel (inox) is defined as a ferrous alloy with a minimum of 10% chromium content.[1] The name originates from the fact that stainless steel does not stain, corrode or rust as easily as ordinary steel. This material is also called corrosion resistant steel when it is not detailed exactly to its alloy type and grade, particularly in the aviation industry
Q:Question about the strength if steel?
The term tensile potential refers back to the quantity of tensile (stretching) rigidity a textile can stand up to in the previous breaking or failing. the in simple terms suitable tensile potential of a textile is calculated by making use of dividing the element of the textile examined (the pass area) by making use of the strain located on the textile, regularly expressed in terms of pounds or much consistent with sq. inch of fabric. Tensile potential is an considerable degree of a textile's skill to accomplish in an utility, and the scale is extensively used whilst describing the residences of metals and alloys.
Q:Is Tempered Steel synonymous with Hardened Steel?
Hardening is the preliminary process. The fully hardened state may be far too brittle for practical use. The tempering process is tailored to reduce the actual hardness, to introduce more flexible alloys. The tempering method employed may be done at relatively low temperatures, but some alloys require prolonged soaking at elevated temperatures. Some may be cooled in air, but others may require quenching to end the process.
Q:what is the difference between white steel and blue steel in reference to sushi knives?
Blue Steel Knife
Q:Is carbon steel a type of alloy?
Yes. it's an alloy of iron and carbon. Carbon steel can either mean plain carbon steel which is steel that doesn't have significant amounts of other elements, like chromium, manganese, or molybdenum. It can also be used to refer to ANY steel that is NOT a stainless steel. Alloy steel is any steel that has greater than 1% of other elements added to it besides carbon. Stainless steel might be in a certain sense be considered alloy steel but I think most people in the steel business consider it as it's own separate material from carbon steels. Many stainless steels contain only trace amounts of carbon, so they should rightly be considered iron-chromium alloys, not steel, which by default refers to iron-carbon alloys. Note that nearly all modern carbon steels also contain 0.2%-0.5% manganese and silicon. Even steels that are otherwise considered plain carbon and not alloy steels. Mn and Si are added because they prevent defects in cast steel ingots, and hot rolled items like billets and plates. However at low levels they don't affect the properties of the steel greatly.
