Q:I was wondering what material most common motorcycle gas tanks are made out of? is it steel? stainless steel? aluminum? what are the advantages and disadvantages or each?
Aluminum Motorcycle Gas Tank
Steel coils can be welded together using various methods. Some of these methods include: 1. Resistance Welding: By applying an electric current to the coil ends, the heat causes them to melt and join. This method is popular for its efficiency and speed. 2. Laser Welding: A high-energy laser beam is used to melt and fuse the coil ends precisely. This technique ensures high-quality welds. 3. Tungsten Inert Gas (TIG) Welding: TIG welding creates a protective atmosphere around the welding area using a non-consumable tungsten electrode and an inert gas like argon. It produces clean and strong welds, making it suitable for steel coil end welding. 4. Plasma Arc Welding: This method involves using a plasma torch to create an electric arc between the electrode and the workpiece. The intense heat generated melts the coil ends for welding. 5. Electron Beam Welding: A high-velocity beam of electrons heats and melts the coil ends. This technique is used for thick steel coils and offers deep penetration and high welding speed. 6. Friction Stir Welding: By using a rotating tool to generate friction and heat, the coil ends soften and fuse together. Although commonly used for joining aluminum coils, it can also be applied to steel coils. These are just a few examples of the different methods available for welding steel coil ends. The choice of method depends on factors such as desired weld quality, production speed, material thickness, and application requirements.
To ensure uniformity, steel coils undergo a series of visual and mechanical tests. First, the coil's external appearance is carefully examined for any visible defects like dents, scratches, or rust. This is crucial to maintain the coil's integrity and prevent potential issues during further processing. Next, non-destructive testing techniques such as ultrasonic or magnetic particle inspection are used to measure the coil's thickness at various points. This helps identify any variations in thickness that could affect the overall quality and performance of the coil. Precise instruments are also employed to measure the coil's width and ensure it adheres to the required specifications. This is important for compatibility with downstream processes and applications. Furthermore, the weight of the coil is measured to verify if it falls within the specified range. Weighing scales or load cells are typically used for this purpose, ensuring consistent weight that meets the required standards. For internal inspection, steel coils may undergo eddy current testing, a non-destructive method that detects surface and near-surface defects. By utilizing electromagnetic induction, this technique can identify irregularities in the metal, such as cracks, voids, or inclusions. In summary, a comprehensive combination of visual inspections, thickness measurements, width checks, weight verification, and internal testing methods ensures thorough inspection for uniformity in steel coils. These rigorous processes guarantee the quality and reliability of the coils, enabling them to meet industry standards and customer requirements.
The maximum load capacity for steel coil storage racks can vary depending on factors such as the design, dimensions, and construction materials of the rack. It is recommended to refer to the manufacturer's specifications or guidelines for accurate information on the maximum load capacity of a specific steel coil storage rack.
Q:Ok I have a neodymium magnet, stuck to my fridge holding a old bottle cap opener for my beer it works fine. At the local rummage sale there was a beautiful cap opener my freind was selling for $0.25 she said had never beenUsed it was like 40 years old it is made a stainless steel. The magnet will not stick to it. I don't understand this looked this up and certain steels are not magnetic, I tried a experiment with my compass it don't point north as should it follows the bottle opener as I move it around it. If not magnetic why is this happening? Also tried placing near another neodymium magnet with a pull of about 200 lbs. Not I tiny bit of attraction to the metal. If so why is the tiny magnet in the compass attracted to it. But not a huge powerfull magnet.
That's interesting that it caused deflection in the compass. A lot of stainless steels may be SLIGHTLY magnetic, because they have small amounts of ferrite or alpha-iron in them. Ferrite is one of the crystal phases of steel. It has a body-centered cubic (BCC) structure and it's responsible for the magnetism of ordinary steels. Adding certain elements like nickel, manganese, or molybdenum, changes the crystal structure of the steel to a face-centered cubic (FCC) structure, which is NOT magnetic. This crystal phase is known as Austenite or gamma-iron. However most iron alloys contain some impurities that may cause the steel to be not completely transformed into the FCC austenite phase, small areas remain as ferrite.
The size range of steel coils can vary depending on the specific application and industry. Generally, steel coils come in a wide range of sizes to accommodate different needs. The width of steel coils can range from as narrow as a few inches to as wide as several feet. Similarly, the thickness of steel coils can vary from very thin gauges, such as 0.005 inches, to thicker gauges exceeding 0.5 inches. The length of steel coils is typically determined by the manufacturing process, but it can be customized to meet specific requirements. Overall, the size range of steel coils is quite extensive, allowing for flexibility and adaptability in various industries, such as automotive, construction, and manufacturing.
Q:In the game RuneScape, the concept of the fictitious metal, Rune has intrigued me. On an equal area AND weight basis (with a possible 10 lb exception) what metal is 256% stronger than steel?
Depending on carbon content, alloy content and heat treatment, steel can have almost any yield strength you want it to. It can be as low as 250 MPa or as high as 1700 MPa. That's more than your 256% difference right there. So maybe the answer should be itself.
Q:Is boron steel or carbon steel a harder metal? Which one is more flexible?
There is really no simple answer to this question. Boron is usually used for a handful of reasons, but most center on high volume low cost production of durable hardened steel. Boron is a very cheap way to get very durable parts with very minimal alloying of expensive materials. It was born of necessity during WW2 and is currently in WIDE use in bulldozer undercarriage. Probably in place of what would otherwise be 4140. Boron steel is quite a bit more difficult to properly heat treat. Better suited to mass production facilities with tight controls, but when done properly provides material just as durable as higher alloys. Not a backyard endeavor such as ht/tempering carbon steel or tool steels without appropriate homework and treatment controls.
Q:Having a new kitchen and would like to know the pros and cons of stainless steel as opposed to white appliances. I can only think of finger marks on the SS, which I believe are difficult to remove. Anyone had both that they could advise please?
A relative had a stainless steel range. It always looked a fingerprinted mess. I have never liked it. To me, it is grey with a sheen. I hate grey. I am a white appliance person all the way. White makes the room look cleaner, brighter and larger and it is easy to keep clean. Stainless is a nightmare to keep clean. Almost forgot to mention, when we bought our house a few years ago, it had a stainless steel range, horribly marked and scratched. I got rid of it, in keeping with white.
In the manufacturing and processing of steel coils, various steel coil edge treatments are employed. These treatments serve to improve edge quality, protect against damage, and facilitate the handling and processing of the coils. Some of the prevalent types of steel coil edge treatments are as follows: 1. Mill Edge: The steel mill provides this standard edge treatment, which is the raw edge of the steel coil generated during the hot rolling process. The mill edge is typically sharp and may exhibit some irregularities. 2. Slit Edge: Slit edge treatment involves slitting the coil to the desired width and subsequently processing the edges to eliminate any burrs or unevenness. Compared to mill edge coils, slit edge coils have smoother edges. 3. Deburred Edge: The deburring process removes any sharp or rough edges from the coil using specialized equipment or techniques, resulting in a smoother and safer edge. Deburred edges find common use in applications where safety and handling are of utmost importance. 4. Rounded Edge: Rounded edge treatment entails rounding the edges of the coil to minimize the risk of damage during handling and processing. This treatment is frequently employed in applications where the coil must be uncoiled or fed into machinery without incurring any damage. 5. Beveled Edge: Beveling involves chamfering or cutting the edges of the coil at an angle. Beveled edges are utilized in applications where easy insertion, joining, or welding of the coil is required. The beveling process also enhances the strength and durability of the edge. 6. Sheared Edge: Shearing is a cutting process that employs high-pressure blades or scissors to cut the coil to the desired width. Sheared edge treatment yields a clean and straight edge, devoid of burrs or irregularities. It is commonly employed in applications that necessitate precise dimensions and a smooth edge. These are merely a few examples of the various steel coil edge treatments commonly employed in the industry. The selection of edge treatment depends on specific application requirements, such as handling, processing, safety, and aesthetics.
