Q: For some reason, if you rub iron oxide or lodestone (both very crumbly, dark, mineral-like materials) into soft, unhardened steel, their particles actually get stuck into the surface of the steel (that is, darkening it). My question is, how does this work? How come iron oxide and lodestone can get stuck, and how come other materials (like silicone carbide, for example) do not?My second question is, are there any materials that can get stuck into steel, that is also blue in color, and how would I best obtain it?: Funny! 100!

Q: On a free standing carport with an 8 inch, 22 foot long aluminum i-beam, would a steel 8-inch i-beam be just as strong? I am looking into it since they are cheaper.: Yes-- just make sure that your connection to the beam is secure. Since you call it an I beam -- I assume that it is steel. Don't do any drilling -- use two heavy duty c-clamps to hang your bar from.

Q: I'm doing a project on stainless steel dining utensils and its a little more difficult than i thought it would be. There are no sites on the web that tells the creator or when it was first used. There's no sites that that i can see of that talk about the history of stainless steel dining utensils, only dining utensils in general. Please help, i can't change my project now ):: The booklet 100 years of WMF (WMF: Württembergische Metallwarenfabrik / Wurttemberg Metal Ware Factory) includes the patent application (or better: trade mark application) for stainless Cromargan Steel for the production of cutlery in 1926. Cromargan was the company's fantasy name for stainless Krupp V2A steel. Page 86 (unfortunately WMF is a German company, the booklet therefore is in German). Has nice pictures anyways. Appendix: I found the text (a bit cut however) in English language (without images and booklet, just HTML). See below.

Q: What are the different methods of cutting steel coils into sheets?: There are several methods used to cut steel coils into sheets, including shearing, slitting, and laser cutting. Shearing involves using a straight blade to cut through the coil, while slitting uses circular blades to make multiple cuts simultaneously. Laser cutting, on the other hand, utilizes a high-powered laser beam to melt through the steel. Each method has its own advantages and is chosen based on factors such as the desired precision, speed, and cost-effectiveness.

Q: How are defects in steel coils repaired?: Defects in steel coils can be repaired through several methods depending on the type and extent of the defect. One common approach is known as welding repair, which involves using specialized welding techniques to fix the defect. This method is typically used for minor defects such as cracks or small holes in the coil. The damaged area is cleaned, prepped, and then welded using appropriate welding rods or wires to ensure a strong and durable repair. For more severe defects, such as large holes or significant damage to the coil, a patching technique may be employed. This involves cutting out the damaged section and replacing it with a new piece of steel. The patch is usually welded to the intact areas of the coil, ensuring a secure and seamless repair. In some cases, defects can also be addressed through grinding or sanding techniques. This is often used for surface defects like scratches or blemishes that do not compromise the structural integrity of the coil. Grinding or sanding the affected area smooths out the defect, improving the appearance and preventing further damage. It is worth noting that the repair method chosen depends on factors such as the specific defect, the material of the coil, and the intended application of the steel. The repair process may also involve additional steps such as heat treatment or surface finishing to restore the coil to its original condition. Overall, repairing defects in steel coils requires the expertise of skilled technicians and specialized equipment. It is crucial to address these defects promptly to prevent further damage and ensure the coil's performance and longevity.

Q: The length of a steel beam increases by 0.78 mm when its temperature is raised from 22 degrees C to 35 degrees C. What is the length of the beam at 22 degrees C (in meters)?I used: L = (0.78 mm)/[(9/5)(.00000645 F)(13)] = 5.17 meters but Mastering Physics said Not quite. Check through your calculations; you may have made a rounding error or used the wrong number of significant figures. I'm confused because this is how we learned this kind of problem in class, so if anybody knows what I did wrong, feel free to correct my errors! Thanks: ? got me is that the whole problem or is there more?

Q: Why is the steel tape tape head not fixed?: It makes sense to be irregular;You can see the standard ruler of steel roll head is a gap, when you take the time to object quantity, the head will indent the gap, so you measure is the size of the head from the head of steel;When you hook the object, the head will pull apart and you'll take the dimension from the end of the steel head.

Q: What are the current trends in the steel coil industry?: Some current trends in the steel coil industry include the increasing demand for high-strength steel coils due to their durability and lightweight properties. There is also a growing focus on sustainability and environmentally friendly practices, leading to the development of eco-friendly coatings and recycling initiatives. Additionally, digitalization and automation are becoming more prevalent, enhancing efficiency and productivity in steel coil manufacturing processes.

Q: I just bought a dpms ar15 and it says if I shoot steel cases (laquer coated) or foreign ammo it voids the warranty. But before I knew this I bought 200 rounds of Russian steel cased anmo. Think I should just shoot there two hundred and not buy anymore? Some people say all they shoot is steel cased ammo and have no problemAny advice is appreciated: I would probably buy a box of 20 brass cased ones and shoot them first to see that the gun works if you really believe that steel cased/foreign ammo voids the warranty. That way you will know that the rifle is functional from the factory. My son has a Rem 700 SPS Varmint that has only fired handloads and there are a couple of other rifles that have never had a factory round in them and the manufacturers claim that hand loads void warranties too.

Q: So...I'm learning about how steel is made and I'm wondering if there is a more environmentally friendy method. I view it as unfriendly b/c of the oxygen that is injected when the steel is in the blast furnace or electric arc furnace. This oxygen bonds w/ the carbon to produce CO and CO2. THis is necessary to reduce the amount of carbon content to produce harder steels. So what other methods are there that can be used w/o having to end up w/ co and co2? thanks: From what I understand of it, US steel is better as the steel is more recycled than Canadian, so a lot of that oxygen / CO2 has already taken place compared to working from ore. The second reason US steel is environmentally ahead of Canadian is that US tends to use Electric Arc, while Canadian uses Basic Oxygen, Basic Oxygen uses more energy than electric arc, and I think it also uses more oxygen, but I would suspect that oxygen that it uses is 'waste oxygen' and not converted into Co2 because the Co2 process is limited by the carbon, and steel only has so much carbon.
