Q: Molton is formed at 2800 F. Thats a fact. Now jet fuel at its hottest is 1800. Where does the other 1000 degress come in? And it was found at the WTC 7 site. Was this hit by a plane? A simple fire COULD NOT produce molton. This is a fact. Molton is formed during controlled demoliton of a building since all the bombs in the buiding go off and its very very hot. The fact there was MOLTON at the site is shocking to some since it is IMPOSSIBLE for molton to form from jet feul alone. Impossible. It needed another source. Now the claim that I'll get is that it weakened the stell but then we would find weak steel not molton. Why do you seem to throw this off of your shoulder? Do you not want to belive it? I'm no jet fuel guy but I know you cannot make molton by using just jet fuel. This is really proof that 9/11 was an inside job.: I think there are things that you are missing here. First of all I looked up the MSDS sheet for Steel from US Steel. Steel is made of all kinds of different metals to start with and the melting/freezing point for steel is 1750 F not 2800 according to US Steel. In addition in the World Trade Center buildings there were all kinds of other materials that are normally used in construction that were all burning at the same time which would have added to the temperatures. Not only was it steel but it was iron, calcium and other building materials too. NIST provides a maximum gas temperature due to WTC fires of 1,000 °C: In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, figure 6-36) Okay I don't know if you know who NIST is but that is the National Institute of Standards and Technology and they are some pretty smart people. They did not say that the steel melted due to the fires, but they did say that the temperatures surely did get high enough to to melt the steel. If US Steel says the melting point for steel is 1750 and NIST says that the temperatures were around 1800 F then that is high enough to melt the steel. I think the key is that there were other materials burning too.

Q: What is the size range of steel coils?: The size of steel coils can vary depending on the specific application and industry, offering a wide range of options. Steel coils are available in various sizes to meet different needs. The width of steel coils can range from a few inches to several feet, accommodating different requirements. Similarly, the thickness of steel coils can vary from very thin gauges, like 0.005 inches, to thicker gauges that exceed 0.5 inches. The length of steel coils is typically determined by the manufacturing process, but it can be customized to meet specific demands. In general, the size range of steel coils is extensive, providing flexibility and adaptability in industries like automotive, construction, and manufacturing.

Q: Why is the selection of steel building erector of extreme importance while starting a new steel building project?: Because if the beaming is screwed up, everything in the building is at risk. Also, if the erector runs late, everything else is delayed. An incompetent erector can actually cause damage to the beams [especially if inadequate bracing leads to collapse] and getting new ones can severely delay the project.

Q: where can i get a thick sheet of steel ? and is steel bullet proff for example if you shoot a bullet on steel will that bullet bounce right off the steel ?: Try the business-to-business yellow pages in your area. A local hardware store can also tell you who to contact. Or search steel plate or sheet metal on the internet to find a local supplier. No, sheet steel is not bullet proof, unless you get heavy plate. Depending on how thick it is, the plate will deform if hit by a high velocity bullet, but usually not enough to matter. Bullets have velocities from about 500 ft/sec up to roughly 3000 ft/sec, depending on the type of weapon used. I wouldn't try to use anything thinner than 3/4 inch. You'll have to experiment and see what it will actually stop. I can't guarantee it'll stop a high-velocity rifle slug. Try it and see.

Q: which is the most tough and durable steel type ??: Speaking of Building Construction, we use grade 450 and 450B not because of toughness, its because it best serves its purpose, reinforcing concrete structure should provide the enough ductility of structure to resist flexure/bending when loads are imposed on it.

Q: I saw this really pretty ring online and it was made of steel. Is this a good ring? If I were to wash my hands with it on, would it rust and turn my finger green?: Steel rust is brown not green! Very much expected to be of one type of stainless steel, and you should have no problem.

Q: What are the different surface finishes of steel coils?: There are several different surface finishes of steel coils, including hot rolled, cold rolled, galvanized, and coated finishes. Hot rolled coils have a rough and textured surface, while cold rolled coils have a smoother and more refined surface. Galvanized coils are coated with a layer of zinc to protect against corrosion, while coated coils have additional layers of paint or other materials for aesthetic or functional purposes.

Q: What are the different types of steel coil surface protection methods?: There are several types of steel coil surface protection methods, including oiling, painting, galvanizing, and plastic film coating.

Q: Are steel coils susceptible to damage during storage or transportation?: Yes, steel coils are susceptible to damage during storage or transportation. Steel coils are often heavy and can be prone to deformation, bending, and scratching if mishandled. Additionally, improper stacking or securing during transportation can lead to shifting or movement of the coils, which can cause damage. Furthermore, exposure to moisture, extreme temperatures, or corrosive substances can also affect the integrity of the steel coils. Therefore, it is crucial to handle, store, and transport steel coils carefully to minimize the risk of damage and ensure their quality and usability.

Q: I know that the steel is significantly harder than when air cooled, but why is the quenched steel harder?: When steel is slowly cooled, lots of carbon diffusion takes place because it is not very soluble in steel at room temperature. The carbon is in solution at high temperatures, and is rejected out of the lattice as it cools. And when this happens, the microstructure will consist of ferrite and pearlite, and the lattice structure will be base centered cubic (bcc). If it is cooled fast enough, then the carbon gets trapped in the interstitial sites of the lattice and distorts it to a body centered tetragonal (same as bcc, but elongated in one direction) This elongation strains the lattice and makes it harder. Also, when cooled fast enough the atoms do not have time to diffuse like they normally would and they shear into place. This forms the hard phase of martensite that is desired of heat treated steel. But then it must be tempered back some because it is too brittle.
