- Q: I understand that damascus sword steel was made by folding the strip of steele double , reheating, hammering, folding again and so forth hundreds of times. Was this the same or very nearly the same techmique the japs used making the sword blades the samari swords?(forgive the misspelling)
- Damascus: A folding technique where the steel is folded over itself many (generally up to sixteen) times, leading to hundreds or even thousands of layers (one fold = 2 layers, two folds = 4 layers, three folds = 8 layers, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, etc.). More folds than sixteen are pointless, as the layers would become thinner than one molecule - which is impossible. This method was developed to removed impurities from the steel (it also removes carbon, which is bad, but can be compensated for to some degree), but modern steel is so pure that Damascus folding is no longer needed. It is now used for aesthetic reasons; Damascus steel looks really good; you can see the layers in the blade. San Mai: Translates to three layers. Layers of softer, lower carbon steel (or iron) is forge welded to layers of harder, higher carbon steel. The lower carbon steel forms the core (and sometimes the sides and/or back), and the higher carbon steel forms the edge. The hard edge will hold its sharpness, the softer core provides shock absorption; making the sword harder to break. Unlike Damascus, San Mai is still very practical. San Mai folds should be invisible; if you can see a San Mai fold the forging was flawed and the blade should be discarded - you'll have to trust your seller that the blade is San Mai - you can't tell by looking. San Mai can be revealed by etching the blade with acid, such as lemon juice, but I don't recommend trying this unless you know what you're doing; you can permanently stain the blade. San Mai swords are more durable (and more expensive) than simple blades. They are more durable (and usually less expensive) than Damascus blades. A blade can be either San Mai or Damascus, or it can be both; Damascus steel which is then San Mai folded. Very cool, looks good and lasts long.
- Q: How are steel coils processed and shaped into specific products?
- Steel coils are processed and shaped into specific products through a series of steps, involving various machinery and techniques. The process begins with the steel coils being unwound and flattened using a decoiler and a leveller. This step ensures that the coils are ready for further processing. Next, the flattened coils are fed into a rolling mill, where they undergo a process called cold rolling. Cold rolling involves passing the coils through a series of rollers to reduce their thickness and improve their surface finish. This process also enhances the strength and hardness of the steel. After cold rolling, the steel coils may undergo additional processes such as annealing or galvanizing, depending on the desired properties of the final product. Annealing involves heating the coils to a specific temperature and then slowly cooling them, which helps to relieve internal stresses and improve the steel's ductility. Galvanizing, on the other hand, involves coating the coils with a layer of zinc to protect them from corrosion. Once the necessary treatments are completed, the steel coils are ready to be shaped into specific products. This is achieved through various methods such as cutting, stamping, or forming. Cutting involves using shears or lasers to trim the coils into specific sizes or lengths. Stamping involves using a die and a press to shape the coils into intricate designs or patterns. Forming, on the other hand, involves bending or shaping the coils using specialized machinery to create curved or contoured products. Finally, the shaped steel products are inspected for quality and undergo any necessary finishing processes such as painting or coating. This ensures that the products meet the required specifications and are ready for distribution or further assembly. In summary, steel coils are processed and shaped into specific products through a combination of steps including unwinding, flattening, cold rolling, annealing or galvanizing, cutting, stamping, forming, inspection, and finishing. Each of these steps plays a crucial role in transforming the raw steel coils into high-quality products used in various industries.
- Q: I felt that my nylon strings don't sound as good as steel ones. Is it okay that I replace them with steel ones, even if my guitar is classical? Thanks.
- Don't. okorder /
- Q: Why can hot rolled coils be placed outside?
- Because the stress of participation should be eliminated
- Q: How are steel coils used in the production of roofing systems?
- Steel coils are used in the production of roofing systems as they are formed into sheets or panels that are then shaped, cut, and fastened to create durable and weather-resistant roofs. The coils provide the raw material for manufacturing various components of the roofing system, such as metal tiles, standing seam panels, or corrugated sheets, which offer excellent strength, longevity, and protection against harsh elements.
- Q: I bought a stainless steel water bottle today. I really like it, but there is no drinking spout, it just has a lid that screws on and off, and an open hole to fill it and drink out of. Is this normal for these bottles? Or do they usually come with a spout to drink from? I don't want to look like an idiot at the gym drinking from this cool bottle with no spout if there's supposed to be one! haha.
- That's normal. I'm sure there are caps that you can get that have a built in spout though.
- Q: I was wondering if anyone knew the grade/type of steel for this product. I'd like to use it as stock for a knife blade, but would like to know the specs so I can determine if it is suitable and, if so, how best to heat treat it.Thanks.PS: I know it isn't stainless, but that leaves a lot of other steel types.

- Q: What are the different types of steel coil finishing tools?
- In the metalworking industry, various tools are utilized to finish steel coils, resulting in enhanced appearance and functionality. Common examples of these tools include: 1. Slitting Machines: These machines effectively cut large steel coils into narrower strips by utilizing sharp circular blades. The outcome is multiple smaller coils with desired widths. 2. Levellers: Used to flatten and straighten steel coils, levellers apply pressure to ensure a perfectly flat and even coil. They are particularly beneficial when coils have undergone deformation during the manufacturing process. 3. Recoilers: After slitting or levelling, recoilers rewind steel coils into a tighter and more compact shape. This process is carried out to create coils of specific diameters or sizes. 4. Edge Trimmers: To eliminate excess or uneven edges from steel coils, edge trimmers are utilized. They efficiently remove burrs, rough edges, and any other imperfections, resulting in a clean and smooth finish. 5. Inspection Machines: These machines are employed to examine the quality of steel coils. They detect defects such as surface imperfections, scratches, or dents, ensuring that only high-quality coils are delivered to customers. 6. Coating Machines: To provide protective coatings to steel coils, coating machines are utilized. These coatings, such as paint, zinc, or other materials, prevent corrosion and enhance coil durability. 7. Packaging Machines: Packaging machines securely wrap steel coils, protecting them during transportation and storage. These machines employ plastic or metal straps, shrink wrap, or other packaging materials to ensure the coils remain intact and undamaged. Overall, these diverse steel coil finishing tools are essential in the metalworking industry, enabling manufacturers to produce high-quality and visually appealing steel coils that meet specific customer requirements.
- Q: Specifically, for the main support beam found in a basement.
- Talk to the supplier of both the products on what is involved in installation, weight bearing over the span you are trying to go without supports,the size of beam, will it affect the height of the room below or will the floor have to go up and the cost how much are you prepared to spend, you will then get your answer
- Q: What are the common defects found in uncoiled steel coils?
- Some common defects found in uncoiled steel coils include surface defects such as scratches, dents, or pits, edge defects like burrs or slivers, and dimensional defects such as variations in thickness or width. Other defects may include coil set (curvature), coil breaks (cracks or fractures), or oil stains. These defects can affect the quality and performance of the steel and may require further processing or inspection before use.
