- Q: I have heard using the BRASS casing is the best thing for an AR-15? Should i just use Brass or Steel?
- Many people have to jam a cleaning rod muzzle end first, using a hammer to bang out steel cased ammo out of an Ar rifle. This has happened to me 3 times and will Never happen again. It said its harder on the extractor, well that is not so but the case will be badly damaged by the extractor and I don't think that is a good thing for any extractor. Any individual pushing steel cased ammo must be selling it...Don't Buy It!!!
- Q: What are the common methods of packaging steel coils for transportation?
- There are several common methods of packaging steel coils for transportation. One widely used method is to use steel strapping or bands to secure the coils together. This method involves tightly wrapping the coils with steel bands and securing them with metal buckles or seals. The strapping helps to keep the coils in place and prevents them from shifting or rolling during transportation. Another common method is to use wooden pallets or skids to stack and transport the steel coils. The coils are placed on the pallets and secured with steel strapping or bands. This method provides stability and allows for easy handling and loading onto trucks or other transportation vehicles. Some steel coils are also packaged in wooden crates or boxes. These crates are typically made of strong and durable wood and are designed to protect the coils from external impacts or damage during transportation. The crates are often reinforced with steel bands or strapping to provide additional strength and stability. In addition to these methods, some steel coils are packaged in specialized containers or units. These containers are specifically designed to hold and secure steel coils for transportation. They often have built-in mechanisms or features that make loading and unloading the coils easier and safer. It is important to note that the specific method of packaging steel coils for transportation may vary depending on factors such as the size and weight of the coils, the mode of transportation, and any specific requirements or regulations in place.
- Q: How much does a steel coil weigh?
- The weight of a steel coil can vary depending on its dimensions and thickness. However, on average, a steel coil can weigh anywhere between 2 to 20 tons.
- Q: What are the common methods of protecting steel coils from corrosion?
- There are several common methods used to protect steel coils from corrosion. 1. Coating: One of the most effective methods is to apply a protective coating on the surface of the steel coil. Various types of coatings such as paint, epoxy, or zinc can be used to create a barrier between the steel and the corrosive environment. These coatings provide excellent corrosion resistance and prevent moisture and oxygen from reaching the steel surface. 2. Hot-dip galvanizing: This method involves immersing the steel coil in a bath of molten zinc, which creates a thick layer of zinc coating on the surface. The zinc coating acts as a sacrificial barrier, protecting the steel from corrosion. Hot-dip galvanizing is particularly effective in harsh environments or for long-term outdoor exposure. 3. VCI (Volatile Corrosion Inhibitor) packaging: VCI packaging is a method where steel coils are wrapped in a specially designed film or paper that contains volatile corrosion inhibitors. These inhibitors vaporize and form a protective layer on the surface of the steel, preventing corrosion. VCI packaging is commonly used for short-term storage or transportation of steel coils. 4. Desiccants: Moisture is a major contributor to corrosion. Therefore, using desiccants such as silica gel or activated alumina can help absorb moisture and maintain a dry environment around the steel coils. Desiccants are often used in conjunction with other protective methods to enhance corrosion protection. 5. Proper handling and storage: Proper handling and storage practices can significantly reduce the risk of corrosion. Steel coils should be stored in a dry environment away from moisture sources. They should also be handled with clean gloves to prevent the transfer of corrosive contaminants. Regular inspection and maintenance of the storage area are essential to identify and address any potential corrosion risks. By employing one or a combination of these methods, steel coils can be effectively protected from corrosion, ensuring their durability and integrity.

Slivers can cause difficulties in further processing and may also affect the surface quality of the final product. 5. Weld defects: In steel coils that are made by welding multiple strips together, weld defects can occur. These defects can include incomplete fusion, porosity, or cracks in the weld area. Weld defects can weaken the steel and affect its mechanical properties, making it unsuitable for certain applications. 6. Shape defects: Shape defects in steel coils can include camber, coil set, or crossbow. These defects can be caused by uneven cooling, improper winding, or tension variations during the manufacturing process. Shape defects can make it difficult to process the steel and may lead to dimensional inaccuracies in the final product. It is essential for manufacturers and users of steel coils to be aware of these common defects and take appropriate measures to prevent or mitigate them. Quality control measures, proper handling procedures, and regular inspections can help in identifying and addressing these defects to ensure the production and use of high-quality steel products.
