- Q: i'm looking into buying a stainless steel ring for somebody as a gift.i'm on a budget (heh) and the ring is about $50.will it rust or tarnish? it'd be embarrassing if i gave it to someone, and it begins rusting :Pthanks
- Stainless steel is a generic term for a huge variety of different alloys. In manufacturing, each steel has different numbers, etc that they go by. Some steel sold as being stainless actually is not. It rusts, like the cheap kitchen knives you see that are left in the sink too long. However, the stainless in jewelry is pretty legit. Overpriced, but legit. It will not tarnish, but it won't stay shiny forever. It might get a little less glossy over time. When it does get re-polished, it takes a long time to do it. But it will not turn black or rust. Good luck.
- Q: What are the challenges in coil recoiling for high-strength steel?
- One of the main challenges in coil recoiling for high-strength steel is the control and management of residual stresses. High-strength steel has a tendency to retain significant levels of residual stresses, which can lead to coil distortion or springback during recoiling. This requires careful process optimization and control to minimize these effects. Additionally, the high strength of the steel can make it more susceptible to cracking or damage during recoiling, necessitating precise handling techniques and equipment. Overall, the challenges lie in achieving uniform coil geometry, minimizing residual stresses, and avoiding any potential damage to the high-strength steel during the recoiling process.
- Q: How are steel coils uncoiled?
- Steel coils are typically uncoiled using a machine called a decoiler or uncoiler, which gradually unwinds the coil by feeding it through a set of rollers. The rollers apply tension to the coil, allowing it to unwind smoothly and evenly. The speed and direction of the uncoiling process can be controlled to match the specific requirements of the application.
- Q: What dangers were there for the steel workers in Pittsburgh under Carnegie?
- All manufacturing jobs of that era were incredibly dangerous, even textile work, but steel work was likely the worst. Men would fall into vats of molten metal, be crushed under huge metal bars, hit by cranes, burned by simple contact with any of the red hot pieces of metal flying all around, and most commonly, die from asphyxiation or lung ailments from the constantly burning fires. Heat stroke was a big killer, too. There was virtually no form of compensation, either for injured workers, or, in the case of death, for their families. The Bessemer method, which Carnegie introduced into the US, was hoped to improve conditions...instead, it merely improved output, and Carnegie's factories after 1900 worked 200,000 men, twelve hours a day, on wages that barely kept their families alive.
- Q: What are the different types of steel coil cutting machines?
- In the market, there is a wide range of steel coil cutting machines available, each tailored to meet specific needs and requirements. Some commonly used types include: 1. Slitting Machines: These machines are utilized to cut steel coils into narrower strips. Equipped with multiple circular blades, they are capable of making precise cuts along the length of the coil, enabling the production of narrower coils or strips. 2. Cut-to-Length Machines: Designed to cut steel coils into specific lengths, these machines possess the ability to accurately measure and cut the coil to the desired length, ensuring uniformity and precision. 3. Rotary Shears: Rotary shears are robust cutting machines that can handle thicker and larger steel coils. Utilizing a rotating blade, they are suitable for cutting thicker gauge materials. 4. Multi-Blanking Machines: Intended for cutting steel coils into multiple smaller blanks simultaneously, these machines have the capability to cut the coil into various shapes and sizes. This makes them ideal for producing multiple parts from a single coil. 5. Slit and Cut-to-Length Combination Machines: These machines integrate the functionalities of both slitting and cut-to-length machines, enabling the cutting of narrow strips and lengths in a single process. They offer versatility and efficiency, saving time and increasing productivity. Each type of steel coil cutting machine possesses distinct advantages and is suitable for specific applications. The choice of machine depends on factors such as coil thickness, desired strip width, required length accuracy, and production volume.
- Q: bullets are normally made out of lead...are there bullets that are completely steel?? (not plated)
- Yes, mild steel has been used, especially in wartime when shortages of materials become problematic. The trouble with using them, though, is that they don't obturate the rifling well (plus the obvious thing that they're hard) so they tend not to shoot well, and they wear barrels quickly.
- Q: What are the common coil packaging methods?
- The common coil packaging methods include stretch wrapping, strapping, banding, and using coil covers.
- Q: Monopolistic competition means all of their products are identical like things in supermarket like milk. There are no high barriers to entry. Oil and steel are all same in all industries.

- Q: How are steel coils protected from mechanical damage?
- Steel coils are protected from mechanical damage through various methods such as using protective packaging materials like wooden crates or metal bands, applying plastic or paper interleaving, and utilizing specialized handling equipment during transportation and storage.
- Q: What are the different methods of pickling steel coils?
- There are several methods of pickling steel coils, including acid pickling, electrolytic pickling, and mechanical pickling. Acid pickling involves immersing the coils in a bath of acid, typically hydrochloric or sulfuric acid, to remove any scale or impurities on the surface. Electrolytic pickling uses an electric current to dissolve the scale and impurities from the steel coils. Mechanical pickling involves using abrasive materials or mechanical brushes to physically remove the scale and impurities from the surface of the coils.
