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.

Q: Can steel coils be customized in terms of size and shape?: Yes, steel coils can be customized in terms of size and shape.

Q: Explain how you could make plastic sink and steel float?: Plastics that are more dense than water will sink. For floating, you need to displace more water than you weight, so assuming steel is 10 times denser than water you will need to displace 10 times as much water weight as your steel occupies. This is easy for a wide hull ship (barge)

Q: What are the different types of steel coil surface treatment options?: There are several different types of steel coil surface treatment options available, each serving a specific purpose and providing various benefits. Some of the common surface treatment options include: 1. Hot-dip galvanizing: This process involves immersing the steel coil in a bath of molten zinc, which forms a protective zinc coating on the surface. Galvanizing provides excellent corrosion resistance and helps in extending the lifespan of the steel coil. 2. Electro-galvanizing: Similar to hot-dip galvanizing, but instead of immersing the coil in molten zinc, an electric current is used to deposit a thin layer of zinc onto the steel surface. Electro-galvanizing provides a smoother and thinner zinc coating, making it suitable for applications that require a more aesthetic finish. 3. Pre-painted or coated: Steel coils can be coated with a layer of paint or other protective coatings before they are formed into various products. This type of treatment provides additional protection against corrosion and enhances the aesthetic appearance of the steel coil. 4. Organic coating: Organic coatings are typically applied to steel coils to provide protection against corrosion and improve the overall durability of the product. These coatings can be in the form of epoxy, polyurethane, or other types of polymer-based materials. 5. Pickling: Pickling is a surface treatment process that involves removing impurities and scale from the steel coil by immersing it in an acid solution. This treatment helps in improving the adhesion of subsequent coatings and prepares the surface for further processing or finishing. 6. Oil coating: Steel coils can be coated with a thin layer of oil to protect the surface from oxidation and rust during storage or transportation. This coating is typically used as a temporary measure and is usually removed before further processing. 7. Shot blasting: Shot blasting involves propelling small metal particles at high velocity onto the steel coil surface. This process helps in removing rust, scale, and other contaminants, providing a clean and roughened surface for better adhesion of subsequent coatings. These are some of the commonly used steel coil surface treatment options. The choice of treatment depends on the specific requirements of the application, such as corrosion resistance, aesthetic appearance, or improved adhesion.

Q: How are steel coils processed for edge trimming or slitting during processing?: Steel coils are processed for edge trimming or slitting during processing by utilizing specialized machinery. The coils are unwound and fed into the machine, where the edges are trimmed off to achieve the desired width. For slitting, the coil is passed through multiple sets of circular blades that cut it into narrower strips. This process ensures precise dimensions and smooth edges, making the steel coils ready for further applications.

Q: How are steel coils used in the production of steel handles?: Steel coils are used in the production of steel handles by being processed and shaped into the desired form for the handle. The coils are first uncoiled and then cut into specific lengths. These lengths are then shaped, bent, and welded to create the handle's structure. The steel coils provide the raw material necessary for the production of sturdy and durable steel handles.

Q: But we've had a problem with bears being attracted to the water in the Intex Inflatable pools, the bear would come at night every so often and push on the sides letting out the water.Would a bear be able to bend a steel frame before I go and spend money?: depends how thick the steel is. Looking at it, I would say yes. Not the frame pieces, but just the walls of the pool.

Q: Where are the coils and the steel plates used? Where did the steel plate come from?: The use of steel coils, refrigerators, washing machines, household appliances, and other industries, parcels are winding.Steel plates can also be found everywhere: airplanes, guns, trains, ships, space shuttles, spaceships, automobiles, etc..Steel plate through mining - sintering - iron smelting - smelting - forming.

Q: What are the trends and developments in the steel coil industry?: Some of the current trends and developments in the steel coil industry include increased demand for high-strength and lightweight steel coils due to their use in various industries such as automotive and construction. Technological advancements have also led to the development of advanced coating methods, improving the durability and corrosion resistance of steel coils. Additionally, there is a growing focus on sustainability and environmental friendliness, leading to the use of recycled steel and the implementation of energy-efficient manufacturing processes in the industry.

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.
