Q:How are steel coils inspected for surface finish after processing?: Steel coils are typically inspected for surface finish after processing using visual and tactile methods. Trained inspectors visually examine the coils for any imperfections, such as scratches, dents, or uneven coating. They also run their fingers over the surface to detect any irregularities. Additionally, advanced technologies like digital imaging systems and laser scanners are employed to provide accurate and detailed analysis of the surface finish.

Q:I want to experiment with making steel and want to especially make it stronger. And also I want to know if its possible to turn a meteorite into steel?: If you really want to do this, you should be getting some books on steel metallurgy rather than asking on Yahoo. ASM sells a Metallurgy for the non-metallurgist that would be a good introduction. Most university libraries will have the full ASM handbook that includes detailed information for different grades of steel (vol 1), heat treatment and surface hardening (vol 4), testing (vols 8-12), and casting (vol 15). A reference for continuous cooling transformation diagrams will also help in designing a heat treatment process. If you want to make something stronger than most commercial steels, you'll need to get into nanotechnology and unconventional steel processing methods like powder metallurgy. You can increase the strength of steel by about 1000% by reducing the grain size from 50 micron (typical for conventional processing methods) to 100 nm (achievable through high-energy ball milling). Though you'd also need to customize the chemistry to stabilize the grain size during the necessary thermal processing, I believe zirconium works well with iron.

Q:Is there any other way of testing whether or not you have a 1944 Steel penny that won't damage the penny. The magnet test doesn't seem to work cause even when I try to get a 2007 penny to stick to the magnet...it won't. So is there some kind of magnet needed? Like power wise or anything like that, if not then I need to know what are other ways of testing the 1944 penny.: Weigh it. I'm not an expert on coins, but if the 1944 was 100% steel, I would expect it to weigh something different then modern pennies. Another test would be to measure the resistance with a micro-ohm meter. This is a specialized device that can measure resistance to a millionth of an ohm. Steel should have a different resistance than the metals used on other pennies. Here are some comments from wikipedia: In 1943, at the peak of World War II, cents of zinc-coated steel were made for a short time due to war demands for copper. A few (the U.S. Mint reports forty) copper cents from 1943 were produced from the 1942 planchets remaining in the bins. Similarly, some 1944 steel cents have been reported. Following 1943, salvaged ammunition shells made their way into the minting process, and it was not uncommon to see coins featuring streaks of brass or having a considerably darker finish than other issues.

Q:I know that mild steel is more brittle than cast iron....but that is all.......please help??Thank you in advance......Ruby:D: Actually, the opposite is true. CAST IRON is generally brittle, while mild steel is not. Cast iron has a carbon content from about 2%-4%. Mild steel has less than one tenth as much carbon as cast iron- around 0.2% - 0.3%. Cast iron also typically has from 1%-3% silicon. Most mild steel contains no more than 0.3% silicon. Steel melts at ~1450 degrees C. The addition of large amounts of carbon and silicon to C.I. lower the melting point to around 1200 C and make it more fluid than molten steel. Obviously this makes it easier to melt and to pour. The main advantage of cast iron is it's cheap to produce. It also has some desirable properties despite it's brittleness. For example it's easy to cut and carve with machine tools. It's also very heat resistant and excellent at absorbing vibration. For this reason C.I. was commonly used for engine blocks and exhaust manifolds in cars and trucks in the past, (Cast aluminum engine blocks are more common these days because Al is much lighter and conducts heat better.) Cast iron also rusts much more slowly than steel which is why it's still commonly used for pipes. C.I. pipes have been known to last 300 years.

Q:Will a stainless steel mesh screen scratch a titanium cup, or vice versa?I have a titanium french press and am thinking about replacing the included press with an all steel one. I am worried about little flakes of titanium or steel getting ground off into the coffee when the press slides in and out. The original press has a polyester cloth for a screen, so nothing scratches.: Steel is usually harder than titanium, at least when both materials are hear-treated to give their best strengths. And a harder material can scratch a softer one. So I imagine that the answer is that it will scratch. However much of the rest of your question is unclear and it may be that the amount of friction between the two is so small that no wear will take place, so there could be no problem. The function of the polyester cloth may be vital in reducing this friction, so that unless you keep this part of the original design, the scratching will become worse no matter which combination of metals are used.

Q:I Don't have a Oxy act. torch but can Get a Propane one. The finished part(s) are .375 x .550 x .185: I think 12L14 is NOT heat hardenable, because it is low-carbon. You may try heating and quenching it, but it won't harden much. It can be hardened by cold-working - drawing or rolling processes. However, these are usually done by the material manufactures, and most machine shops do not have the capability to do this in house. Can you try 1144 steel instead? 1144 is medium-carbon (0.44%), and heat treatable. It is also free machining grade like 12L14. Other medium carbon steels are also heat hardenable: 1040, 1050, etc.

Q:What are the common methods of slitting or shearing steel coils?: The common methods of slitting or shearing steel coils include: 1. Rotary Shearing: This method involves using a rotary shear machine that uses a set of rotating blades to cut through the steel coil. The blades move in a circular motion, slicing through the coil to create individual strips of the desired width. 2. Scissor Shearing: Scissor shearing is another common method of cutting steel coils. It involves using a pair of scissor-like blades to make the cuts. The blades are typically operated by hydraulic or mechanical systems, and they cut through the coil by exerting pressure on the material. 3. Slitting: Slitting is a popular method used to cut steel coils into narrower strips. It involves passing the coil through a set of circular blades, known as slitters, which are set at specific distances apart. The slitters cut through the coil, creating multiple narrower strips of the desired width. 4. Guillotine Shearing: Guillotine shearing is a method that uses a large, powerful guillotine machine to cut through the steel coil. The machine features a long blade that moves vertically to shear the coil. This method is often used for thicker steel coils and can produce clean, straight cuts. 5. Laser Cutting: Laser cutting is a more advanced method that uses a high-powered laser beam to cut through steel coils. The laser beam is directed by computer-controlled systems, allowing for precise and accurate cutting. Laser cutting is often used for complex shapes or when high precision is required. Each of these methods has its advantages and is suitable for different applications. Factors such as the thickness of the steel coil, desired strip width, and the level of precision required will determine the most appropriate method to use.

Q:How are steel coils used in the production of industrial boilers?: Steel coils are used in the production of industrial boilers to form the main body and components of the boiler, such as the shell, tubes, and headers. The coils are shaped and welded together to create a strong and durable structure that can withstand high pressure and temperature conditions. Additionally, the use of steel coils ensures the boiler's efficiency and longevity, as steel is known for its excellent heat transfer properties and resistance to corrosion.

Q:What are the dimensions of steel coils used in the automotive industry?: Steel coils used in the automotive industry come in various dimensions, which are determined by the specific application and requirements. Normally, the thickness of these coils falls between 0.5mm and 3mm, while the width ranges from 500mm to 2000mm. The length of the coils is subject to variation, depending on the production process and customer specifications. Furthermore, the weight of the coils can range from a few hundred kilograms to several tons. It is worth mentioning that these dimensions serve as general guidelines and may differ based on the particular needs of the automotive manufacturer.

Q:How do steel coils contribute to the construction sector?: Steel coils contribute to the construction sector in several ways. Firstly, they are used to manufacture structural components such as beams, columns, and steel frames, which provide strength and support to buildings and infrastructure. Secondly, steel coils are used to produce reinforcement bars that are embedded in concrete, enhancing its tensile strength and durability. Additionally, steel coils are utilized in the construction of bridges, pipelines, and other large-scale projects that require robust and long-lasting materials. Overall, steel coils play a vital role in the construction sector by providing the necessary materials for sturdy and resilient structures.
