- Q: How long can steel coils be stored before they need to be used?
- The storage duration for steel coils can vary depending on various factors such as the type of steel, environmental conditions, and proper storage techniques. However, generally, steel coils can be stored for an extended period, ranging from several months to a few years, as long as they are stored in a controlled environment to prevent corrosion and damage.
- Q: How are steel coils used in the energy sector?
- Steel coils are used in the energy sector primarily for the construction of power plants and transmission infrastructure. They are used to manufacture various components, such as pipes, tanks, and structures, which are essential for the generation, distribution, and storage of energy.
- Q: Can steel coils be cut or trimmed after delivery?
- Yes, steel coils can be cut or trimmed after delivery using various cutting methods such as shearing, slitting, or laser cutting, depending on the desired specifications and requirements.
- Q: How does the steel coil market vary regionally?
- The steel coil market varies regionally based on factors such as demand, production capacity, and market dynamics. Different regions have different levels of industrial development and infrastructure, which can affect the demand for steel coils. Additionally, variations in raw material availability, labor costs, and government policies also contribute to regional differences in the steel coil market. For example, developing regions may have higher demand for steel coils due to infrastructure projects, while mature markets may focus on specialized steel coil products for specific industries. Overall, regional variations in the steel coil market reflect the unique economic and industrial characteristics of each region.
- Q: How are steel coils inspected for defects?
- Steel coils are inspected for defects through visual inspection, non-destructive testing methods such as ultrasonic testing or magnetic particle inspection, and dimensional measurements. These inspections help identify any surface defects, cracks, or irregularities in the steel coils.
- Q: what do they use to make stainless steel?and can stainless steel be melted again and again without losing it's Specifications
- The stainless steel is a family of ferrous alloys containing at least 11% chromium. The effect of this amount of chromium in steel in reducing corrosion is dramatic. There are many grades of stainless steels. By varying the chemical composition, heat treating, and cold-working, a wide range of properties is achieved. There are three types of precipitation hardening stainless steels: *martensitic types, which are supplies in the martensitic condition, are hardened by a simple aging treatment of the fabricated part. *Semi austenitic types, which are supplied in the austenitic condition, are transformed to martensite by special heat treatment before precipitation hardening. *the austenite in the austenitic types is precipitation hardened directly. The heat treatments of precipitation-hardening stainless steels are chosen to optimize mechanical properties. Precipitation hardening generally results in a slight increase in corrosion susceptibility and an increased susceptibility to hydrogen embrittlement.
- Q: What are the different coil edge options?
- There are several different coil edge options available, including open coil, continuous coil, offset coil, and pocket coil. Each type of coil edge offers unique features and benefits. Open coil edges are interconnected and provide a durable and supportive foundation. Continuous coil edges are made from a single piece of wire and offer enhanced stability and motion isolation. Offset coil edges have an hourglass shape for improved contouring and pressure relief. Pocket coil edges consist of individual fabric-encased coils that move independently, offering personalized support and minimizing motion transfer. Ultimately, the choice of coil edge depends on personal preferences and desired sleeping experience.
- Q: I personally don't believe the story of 8 guys who flew small planes can navigate passenger jets into buildings hundreds of miles away with that precision. It just doesn't make sense.I am wondering what the story surrounding the molten steel was, how could molten steel have been produced when fuel from the planes wasn't hot enough (it melts at 2850 degrees)?
- that's just it: there wasn't very much molten steel for the very reason you point out. Jet fuel burns at 800° to 1500°F. This is not hot enough to melt structural steel. However, engineers say that for the World Trade Center towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength. Steel will lose about half its strength at 1,200 degrees F. The steel will also become distorted when heat is not a uniform temperature. after the collapse, a LOT of folks took a look at the remains. the result was the conclusion that the fire caused the central core of the building to weaken. When the floors collapsed one on top of the other, the weight was too much for the weaked core to bear, causing the result we are all familiar with. hope this helps
- Q: How are steel coils inspected for surface finish using profilometry?
- Steel coils are inspected for surface finish using profilometry by measuring the surface topography using a profilometer. The profilometer scans the surface of the steel coil and records the deviations from the ideal surface. This data is then used to determine the roughness, waviness, and other surface parameters of the steel coil, providing a quantitative assessment of its surface finish quality.
- Q: I'm ordering a Pair of tongs(a tool used to dig quahogs in bays that scrapes the bottom constantly) and what type of metal would be the best to fabricate it, steel or stainless steel?
- Stainless Steel is an allow of Chrome and Steel and several other additives. There are at least 100 types of Stainless.. Most common is 300 Series , that the cheapest and used in household stuff. Then there is the 400 series in that series is a stainless that can be heat treated because it contains sufficient carbon to do so. I would say if its wear you are looking for Stainless is not wear resistant to the extent other steels are. You want a heat treatable oil hardenting steel for that purpose. A good example and an old reliable one is what is called O-1 or oil hardening one. It can be heated with a torch at the wear end and quenched in oil right on the fab site. to a hardness of Rockwell C of about 55 or so and wears well. I suppose the best basket would be a 300 Series stainless to reduce rusting with end pieces that are probably bolted on made of O-1 heat treated to RC of about 55 or so. Of course if you make the wear ends removable with bolts, you can really get some wear steels for those wear parts You can use High Speed Steel RC=95, Drills are high speed steel. and even a material called Hasteloy next to carbide in hardeness. I suspect those baskets are made of Stainless Steel with wear ends of another material as ive discussed above.
