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): Actualy, the secrets of forging Damascus steel has been rediscovered. In the 1970s, a Russian scientist found that he could duplicate the steel found in old Damascene swords. While it is true that such swords (which have to be made by hand) would be more expensive than usual, you must keep in mind that the majority of Damascus swords are still forged in Damascus. Syria is a highly inexpensive country, and the price of a Damascus blade, while being expensive to Syrians, would be cheap to Westerners. In reference to your question about wether there is anything special about Damascus steel, the answer is yes. At the time of its creation, Damascus steel was the lightest and most flexiable metal known to man, even lighter than the steel Katana swords used by the Samurai of Japan. During the Crusades, Europeans reported that the Arab blades were capable of bending in the wind, and floating on water. While these are certainly exaggerations, they are proof that Damascus blades were far lighter and stronger than the crude iron weapons used by the Crusaders.

Q: What are the different coil leveling methods used for steel coils?: There are several coil leveling methods used for steel coils, including roller leveling, stretcher leveling, and tension leveling. Roller leveling involves passing the coil through a series of rollers to remove any curvature and create a flat surface. Stretcher leveling involves stretching the coil in different directions to remove any shape irregularities. Tension leveling applies tension to the coil during the leveling process to eliminate any residual stresses and create a uniformly flat product.

Q: The guy at this one pawn shop told me that stainless steel is better because it is just as strong and will not rust. The guy at the other pawn shop said that you need high carbon steel for a good sword because stainless steel breaks easily and that damascis is the best kind of steel for swords.: Modern Sword Steels: Stainless - Used in decorative swords and knives. Stainless steel blades longer than twelve inches are too brittle for full contact use. 1045 Carbon - Strong, but soft compared to higher carbon steels. Reasonably cheap and acceptable for full contact use. 1060 Carbon - Harder than 1045, but not brittle. Holds a keen edge and is very durable. Somewhat expensive, but great for full contact use. 1095 Carbon - Sacrifices the durability of lower carbon steels for better edge retention and increased hardness. Somewhat expensive, but tough enough for full contact use. 5160 Spring - Extremely tough and durable. Great for full contact use when properly heat treated. 9260 Spring - Amazingly resilient and durable, but not unbreakable. Excellent for full contact use. T10 Tool - Exceptionally hard and tougher than other steels with similar carbon content. Keeps a good edge without sacrificing durability. Can be expensive, but is still great for full contact use. L6 Bainite - Can be very expensive, but is the toughest steel on the market when properly heat treat. Excellent for full contact use, but requires additional maintenance to prevent rust and corrosion. About Damascus Steel: Historical Damascus blades were made from wootz, an Indian steel with unique properties. The technique for making this type of steel has been lost, but there have been many attempts to recreate it. The patterns found on Damascus steel blades are a direct result of the sword-making process and are not entirely dependent on the type of steel used. Damascus swords were the finest blades of their time.

Q: A friends of mine says he has balls of steel and i told him i would melt em off with lava. He said it wouldnt work. i disagree: united is right! its hard to tell the temp... Because lava is not just obsidian, or pillow lava... its several different types of elements. It just depend on ground chemistry.

Q: What are the common international standards for steel coils?: The common international standards for steel coils include ASTM A653/A653M, JIS G3302, EN 10346, and GB/T 2518. These standards specify the requirements for the chemical composition, mechanical properties, and dimensions of steel coils used in various industries.

Q: What are the different types of steel coil finishes used in architectural applications?: There are several different types of steel coil finishes that are commonly used in architectural applications. These finishes are applied to steel coils to enhance their appearance and provide additional protection against corrosion and weathering. Some of the most popular types of steel coil finishes used in architectural applications include: 1. Mill Finish: This is the most basic type of steel coil finish, where the coil is left untreated after being rolled. It has a dull, gray appearance and is often used in industrial and structural applications where aesthetics are not a primary concern. 2. Hot-Dip Galvanized: In this finish, the steel coil is immersed in a bath of molten zinc, which creates a thick layer of zinc coating on the surface. This finish provides excellent corrosion resistance and is commonly used in outdoor architectural applications such as roofing, gutters, and siding. 3. Galvalume: This finish is similar to hot-dip galvanized, but instead of pure zinc, it uses a combination of zinc and aluminum. Galvalume-coated steel coils offer superior corrosion resistance and are often used in high-end architectural applications, such as metal roofing and wall panels. 4. Pre-Painted: In this finish, a layer of paint is applied to the steel coil before it is shipped to the customer. This allows for a wide range of colors and finishes to be achieved, making it a popular choice for architectural applications where aesthetics are important. Pre-painted steel coils are commonly used in exterior cladding, garage doors, and decorative panels. 5. Stainless Steel: This finish is achieved by using a steel alloy that contains a high percentage of chromium. Stainless steel coils have excellent corrosion resistance and are often used in architectural applications where a clean, modern look is desired, such as handrails, elevator interiors, and kitchen appliances. Each type of steel coil finish offers unique advantages and is suitable for different architectural applications. The choice of finish depends on factors such as the desired appearance, level of corrosion resistance required, and the specific environmental conditions the steel will be exposed to.

Q: What are the pros and cons to selecting a graphite shaft sand wedge over steel shaft?: First question, are you guy or girl? stronger or weaker? Steel shaft gives you consistency over graphite because of the weight. For example, Tiger once used a steel shaft in his driver because steel shaft's weight gives him consistency. Key point is he can handle the weight (110g +). Same with you, steel shaft is preferred as it gives you consistency. It's also heavy enough that you can let the natural weight, aka gravity, to let you hit thru the rough, sand, etc.. key point is if you can handle the weight.

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: For a structural product you want tubing instead of pipe. ERW (Electric resistance welded) steel tubing is generally a fairly good compromise between cost and strength. They are available in various wall thicknesses for either lighter weight or greater strength. DOM (dimensioned over mandrel) tubing generally uses a stronger steel allow and is more dimensionally uniform but the cost is much higher. These products are probably available at a local steel supplier. They are both mild steel so they can be arc welded or brazed with ease. Strength of these steel alloys is generally about 70,000 psi so you need to analyze the specific applied stress over the specific surface area to determine what wall thickness you need. If you are applying tension or compression to pins in holes in the tubing, you could braze in hardened steel bushings. You would bore a larger hole in the tubing in which to insert the bushing. Bushings would distribute the force over a significantly larger surface area and the holes will not tend to elongate.

Q: I have an old classical guitar, which uses nylon strings. ive never really liked the sound produced by the nylon, so im curious if you can use a classical guitar with acoustic guitar steel strings. thanks!: NO ! NO! NO! Do not put steel strings on a classical guitar!! The increased tension can actually damage the guitar by causing the top to warp and can eventually pull the bridge right off of the guitar! I have seen it happen more than once! Ignore the other post, they are wrong! Classical guitars are designed to use nylon strings only!

Q: What are the different methods of coil flattening for steel coils?: There are several methods of coil flattening for steel coils, each with its own advantages and limitations. Some of the most commonly used methods include: 1. Roller leveling: This method involves passing the steel coil through a series of rollers that apply pressure to flatten the coil. The rollers can be adjustable to achieve the desired level of flatness. Roller leveling is a versatile method that can handle a wide range of coil sizes and thicknesses. 2. Precision leveling: This method utilizes a more sophisticated leveling machine that applies pressure on specific areas of the coil to eliminate any waviness or defects. Precision leveling is often used for high-quality steel coils that require extremely flat surfaces. 3. Stretch leveling: Also known as tension leveling, this method involves stretching the steel coil beyond its yield point, causing it to permanently deform and flatten. Stretch leveling is commonly used for thinner gauge coils and can effectively remove coil set and crossbow defects. 4. Temper rolling: This method involves subjecting the steel coil to a controlled low-temperature heat treatment followed by cold rolling. The combination of heat and cold rolling helps to relieve internal stresses and improve flatness. Temper rolling is particularly suitable for coils that require enhanced surface quality. 5. Laser flattening: This advanced method utilizes laser technology to selectively heat and flatten specific areas of the coil. Laser flattening is highly precise and can correct localized defects or unevenness, but it is typically used for smaller coils due to its higher cost. It is important to note that the selection of the most appropriate method for coil flattening depends on various factors, including the desired flatness requirements, coil dimensions, material properties, and production budget.
