- Q: Well the other day i told my friend that when you put a compass near steel it will screw up and he said only magnets do that then i showed him and it worked then he said: that'ss because steel has its own magnet in it coz it builds up static electricity is that correct what he said? thanks
- If you sprinkle iron filings near a bar magnet (on paper, etc.) the filings will try to line up with the magnetic field (because iron atoms behave like tiny magnets). Bringing the compass near steel (mainly iron with a little carbon) will cause the iron to try to align with the magnet of the compass needle, however, because the needle is free to swing it also aligns with the magnetic field set up between the needle and steel. Any static electricity would have nil effect on the magnetic field.
- Q: What are the common sizes of steel coils used in the industry?
- The common sizes of steel coils used in the industry vary depending on the specific application and requirements. However, some standard sizes include 36-inch, 48-inch, and 60-inch widths, with thicknesses ranging from 0.014 inches to 0.125 inches. Ultimately, the size of the steel coil is determined by factors such as the intended use, manufacturing process, and transportation considerations.

- Q: What are the different methods of shearing steel coils?
- There exist various approaches to shearing steel coils, each with its own unique pros and cons. Some of the most prevalent methods include: 1. Guillotine Shearing: This technique involves the use of a guillotine-like machine that vertically moves a blade to slice through the steel coil. Guillotine shearing provides high efficiency and accuracy, making it suitable for large-scale industrial production. However, it can lead to deformation or burrs on the cut edges. 2. Rotary Shearing: In rotary shearing, a set of rotating blades is employed to cut through the steel coil. This method enables continuous cutting, making it ideal for high-speed production lines. It ensures a clean and precise cut, but necessitates regular maintenance and blade sharpening. 3. Slitting: Slitting entails passing the steel coil through circular blades that create multiple parallel cuts. This method is commonly used to produce narrower strips from wider coils. It offers great precision and the ability to generate multiple strips simultaneously. However, slitting may result in edge burrs or camber on the strips. 4. Laser Cutting: Laser cutting utilizes a high-powered laser beam to melt or vaporize the steel coil along a predetermined path. This method offers exceptional precision and can cut intricate shapes or patterns. It is commonly employed for specialized applications where accuracy is crucial, although it can be relatively costly. 5. Waterjet Cutting: Waterjet cutting employs a high-pressure stream of water mixed with abrasive particles to cut through the steel coil. This method is versatile and can handle various materials and thicknesses. It is especially useful for cutting heat-sensitive materials or for applications requiring minimal distortion. 6. Plasma Cutting: Plasma cutting involves ionizing a gas to create a plasma arc that melts and blows away the steel coil. This method is fast and efficient, making it suitable for cutting thick steel coils. However, it may produce a wider heat-affected zone compared to other methods. 7. Electrical Discharge Machining (EDM): EDM employs electrical discharges to erode the steel coil and achieve the desired shape. This method is commonly used for intricate or delicate cutting tasks that demand high precision. It is particularly effective for hard materials. Each method of shearing steel coils possesses its own set of advantages and limitations, and the choice depends on factors such as the required precision, speed, material thickness, and the desired end-product.
- Q: What are the different methods of surface treatment for steel coils?
- There are several methods of surface treatment for steel coils, including hot-dip galvanizing, electro-galvanizing, chromating, and painting.
- Q: How are steel coils used in the manufacturing of springs?
- Steel coils are used in the manufacturing of springs by being formed into a helical shape, allowing them to store and release energy when subjected to force or pressure.
- Q: We are going to build a house with a steel frame.Someone told me today that these houses have problems with humidity.Is that true?Please tell me all you know..
- That's a first for me. The only draw back to a steel frame home is the cost, not only in material but also in labor. They do make a great home with proper installation. Make sure your contractor and framing crew have experience with metal frame construction. There is some differences in building codes, etc. Good Luck and happy building.
- Q: What are the different testing methods used for steel coils?
- There are several testing methods used for steel coils, including visual inspection, dimensional measurements, hardness testing, chemical composition analysis, and various non-destructive testing techniques such as ultrasonic testing, magnetic particle testing, and eddy current testing. These methods help ensure the quality and integrity of steel coils by detecting any defects, flaws, or deviations from the required specifications.
- Q: Are they made using the same processes, or is tempered steel made without the quenching process?
- No. Not quite. The term 'Hardened steel' is often used to refer to 'Heat treated steel'. There are two separate steps in heat treatment. First the red hot steel is 'quenched' (rapidly cooled). This yields maximum hardness ,but the steel may be too brittle for the intended purpose. The next stage, 'tempering' is heating to a limited temperature, and slow cooling. This reduces the hardness somewhat, depending on the re-heat temperature, but restores some of the toughness lost in the first stage.
- Q: Search the internet for 'Frost Clipper Knife'. This knife comes in either stainless or carbon steel. I have a friend who has one (stainless steel) and he is very impressed with it, but I have heard that Carbon Steel blades are better? Discuss...
- If your talking about a folding pocket knife, I think that it's basically six one way and a half dozen the other. I actually do prefer stainless for my pocket knives. I don't want to oil a knife to the degree I feel carbon requires, only to then stick it my pocket to attract dirt to the knife and oil to my pants. I'm the exact opposite on sheath knives though. I like 1095 carbon steel, plain edge sheath knives. I'll thrash on them HARD, and I rarely have major edge problems. Of course, I require them to be coated with some kind of powder coat or the like, because they can rust, but I do try and keep them clean and dry when in the sheath, so they won't pit the uncoated edge. My reasons for this sheath knife preference is multi-fold. First, these knives are simply affordable. I don't spend $80 dollars on a outdoors sheath knife. I use the tool too hard to want to spend more. I don't like the more traditional stainless steels such as AUS-8, 420HC, and 440C (not to mention the HORRENDOUS 440A) because I feel that the all else being equal, a stainless blade will bend before a carbon blade will break. I also think that carbon holds an edge at least as well, if not better, than traditional stainless, and it's much easier to hone. I don't know much about these new laminates, other than the very hard, but not so tough. They seem to be POSSIBLY too brittle for my use. That, combined with the fact that they cost a FORTUNE, means that I just won't be considering them.
