- Q: - I'm considering doing my physics coursework on the uses of Mild Steel in skyscrapers and construction, would this be right? Some sources tell me mild steel is too weak, others say it is fine
- Mild steel doesn't really mean anything, technically. In today's world all steel is mild steel unless it's high carbon or alloy, which are mostly tool steels. You'll need to study steel much deeper than that to accomplish any real physics work relating to steel.
- Q: How are steel coils inspected for oil or rust residues using chemical analysis?
- Chemical analysis techniques can be employed to inspect steel coils for the presence of oil or rust residues. One widely used method is Fourier transform infrared spectroscopy (FTIR), which involves subjecting a small sample of the steel coil to infrared radiation and analyzing the resulting infrared spectrum. By identifying specific chemical bonds indicative of oil or rust residues, this technique can effectively detect their presence. For oil residue detection, a common approach is to examine the FTIR spectrum for a peak at approximately 2920 cm-1, which corresponds to the stretching vibration of C-H bonds in hydrocarbon chains. The observation of this peak signifies the existence of oil residues on the steel coil. To identify rust residues, the FTIR spectrum is scrutinized for characteristic peaks associated with iron oxide or hydroxide compounds. For instance, the presence of a peak at around 560 cm-1 suggests the presence of iron oxide (FeO) or iron hydroxide (Fe(OH)3). Apart from FTIR analysis, other chemical analysis techniques like X-ray fluorescence spectroscopy (XRF) or energy-dispersive X-ray spectroscopy (EDX) can also be employed. These methods provide information about the elemental composition of the steel coil, enabling the identification of specific elements linked to oil or rust residues, such as carbon or iron. In essence, the chemical analysis of steel coils for oil or rust residues offers a dependable and precise means of ensuring the coils' quality and cleanliness before further processing or utilization.
- Q: What is the strongest steel ever made.
- Wootz is laughable. A modern car spring has more tensile strength, not to mention better purity in manufacturing. Alpha B is right. My answer would be NS110. While wootz was the source of the original damascus steel. The manufacturing process was much like many crucible type steels of the past. And they were not used by japanese smiths. A traditional japanese sword was made from the ground up. Smelting the iron laden sand into Tamahagane. Which is a pumice like crude steel. It would be forged, and diamond powder would be applied and hammered into the skin. It would then be folded repeatedly to homogenize the blade. For what you are asking for now. I would say that 1/2 mild steel plate should work nicely.
- Q: How are steel coils inspected for elongation using elongation testers?
- Steel coils are inspected for elongation using elongation testers by following a specific procedure. First, a representative sample is taken from the steel coil, which is then prepared for testing by cutting it into a specific size and shape. The sample is usually in the form of a flat strip. The prepared sample is then placed into the elongation tester, which consists of two clamps. One end of the sample is securely held in one clamp, while the other end is held in the other clamp. The clamps are designed to prevent any slippage during the testing process. Once the sample is properly clamped, the elongation tester applies a tensile force to the sample. This force gradually increases, causing the sample to elongate. As the sample elongates, the tester measures the change in length using a precision measuring instrument, such as a strain gauge or an extensometer. The elongation tester records the original length of the sample before the test and continuously measures the length as the force is applied. The elongation is calculated by subtracting the original length from the final length of the sample and then dividing it by the original length. This gives the percentage of elongation. The obtained elongation value is compared to the specified elongation requirements set by industry standards or customer specifications. If the elongation falls within the acceptable range, the steel coil is deemed to have passed the elongation test. If the elongation value exceeds the allowable limits, the steel coil may be rejected or undergo further investigation to determine the cause of elongation. Overall, the process of inspecting steel coils for elongation using elongation testers involves taking representative samples, clamping them securely, applying a tensile force, measuring the change in length, and calculating the percentage of elongation. This helps ensure the quality and mechanical properties of the steel coils, thereby meeting the desired standards and requirements.
- Q: what is the difference between stainless steel 304 (AISI 304) and stainless steel 310 (AISI 310) COR-TEN A
- Weathering steel will rust, but the rust will be adherant and not flake off and be replaced by new rust. Therefore once it rusts it will pretty much stop rusting any more. One (severe) down side is that anything around it will be streaked with rust stains and it will look awful. Some bozo with the Texas Department of Transportation designed a number of freeway interchange overpasses here in Houston using Cor-Ten steel and all of the concrete supports are streaked with red rust stains and it looks like hell. Cameron built an office building here in Houston with a Cor-Ten facade and it is streaked with rust too. They should have gone ahead and spent the money and painted them, but they didn't.
- Q: How do steel coils contribute to the aerospace manufacturing industry?

- Q: How are steel coils tested for flatness and straightness?
- Steel coils are tested for flatness and straightness using a variety of methods. One common method is to pass the coil through a series of rollers that apply pressure and measure any deviations in the surface. Another method involves using laser sensors to scan the entire coil and detect any irregularities. Additionally, visual inspections are conducted to identify any visible imperfections or distortions.
- Q: Hi all.I'm working on a project which requires about 3 steel pipes at 25mm in diametre and about a foot each in length.The qualities I need with the steel is that:1. I need it to be easy enough to weld together2. I need to be able to drill holes through them with a basic drill (I could buy different bits, that's fine)3. I need the steel to be able to take short intense repeated bursts of strain through said holes4. The lighter the steel the better5. Could I please have a ballpark figure for price. I can't imagine such a small amount of steel would cost too muchThank you in advance for your replyRegardsSean
- I do not understand what is meant by, ...repeated bursts of strain through said holes, but I would think that standard a pipe for home plumbing would do. In my vicinity, and I practice own home plumbing, I buy a whole pipe 6 meters long for about the equivalent of $(20-15). A local plumber might give you the short pieces you after for free.
- Q: I have heard that heating the steel and applying oil will help with corrosion, and will give that aged look. I would like to know finishes available without painting. thanks
- No, I don't think the oil will do what you want. I have heated and quenched metal in oil several times (to harden it) and it did not give a finish to steel. I have heard of heating steel to a high temperature (red) and putting powdered sulfur on it, it will make a black finish. BUT, sulfur stinks and you would not do this indoors. And I don't know what the results would be like for indoor use. At the hardware store, you can find something like POR (paint on rust), a brand name of rust neutralizer. There are others. You spray it on (or paint) and it will turn rust into a glossy black material. Other than that, I think paint is your best option. Check out the new finishes they have now, if you haven't checked, they have come a long way. If you let them dry completely (in the sun) the spray can finishes are very durable. Good luck! Ooops, I forgot about gun finishes. Yes, some are blue, you might be thinking of that, but that is only if you put several coats on. One coat might do it. Plus, there are other colors, such as black (see the parkerizing link on the list). Here is a good company, they can be lots of help, too.
- Q: How are steel coils inspected for camber?
- Steel coils are inspected for camber using various methods to ensure their quality and suitability for further processing. One common method is visual inspection, where trained inspectors examine the coils for any visible signs of camber. They look for any deviation from a perfectly straight surface, such as a bow or a curve, which indicates the presence of camber. Another method involves using specialized equipment like straightedges, measuring tapes, and laser devices. Inspectors place the straightedge along the length of the coil to check for any gaps or spaces between the coil and the straightedge. If there is a significant deviation, it indicates the presence of camber. Measuring tapes are also used to measure the distance between the coil and the straightedge at multiple points along the length of the coil. This allows inspectors to determine the extent of camber and whether it falls within the acceptable tolerance limits. In some cases, laser devices are used to provide a more accurate measurement of camber. These devices emit a laser beam that is reflected off the coil's surface and is then analyzed to determine the presence and magnitude of camber. Additionally, advanced technologies such as computer vision systems and artificial intelligence algorithms are also being employed in the inspection process. These technologies can analyze images or videos of the steel coils and automatically detect any camber, providing accurate and efficient inspection results. Overall, the inspection of steel coils for camber involves a combination of visual inspection, manual measurements using straightedges and measuring tapes, as well as the implementation of advanced technologies. This multi-faceted approach ensures that camber is effectively detected and controlled, thus maintaining the quality and integrity of the steel coils.
