- Q: I know that they have steel shot in smaller sized pellets....say, number 4 shot. I guess it's for waterfowl, etc.Do they make steel buckshot? If not, why not? Would the pellets be too heavy? Wouldn't they have excellent penetration ability?
- No Steel Buckshot ...Yet... The whole idea behind steel shot was because there were a very large number of migratory birds, Geese, Ducks, etc dying after being hit with lead shot and developing infections, and lead poisoning, that ultimately killed or crippled too many birds. The Federal government stepped in and made Steel Shot a requirement for hunting all migratory birds. I think the biggest reason that Steel Buckshot isn't made yet is because it can only be fired out of modern, newly manufactured shotgun barrels and unless you have a shotgun designed to be used with steel shot, it would be damaged along with chokes made for lead shot only..I have no doubts that it's probably coming in the near future....Note* Penetration was never an issue, nor was the weight.........
- Q: How are steel coils processed and shaped into specific products?
- Steel coils are processed and shaped into specific products through a series of steps, involving various machinery and techniques. The process begins with the steel coils being unwound and flattened using a decoiler and a leveller. This step ensures that the coils are ready for further processing. Next, the flattened coils are fed into a rolling mill, where they undergo a process called cold rolling. Cold rolling involves passing the coils through a series of rollers to reduce their thickness and improve their surface finish. This process also enhances the strength and hardness of the steel. After cold rolling, the steel coils may undergo additional processes such as annealing or galvanizing, depending on the desired properties of the final product. Annealing involves heating the coils to a specific temperature and then slowly cooling them, which helps to relieve internal stresses and improve the steel's ductility. Galvanizing, on the other hand, involves coating the coils with a layer of zinc to protect them from corrosion. Once the necessary treatments are completed, the steel coils are ready to be shaped into specific products. This is achieved through various methods such as cutting, stamping, or forming. Cutting involves using shears or lasers to trim the coils into specific sizes or lengths. Stamping involves using a die and a press to shape the coils into intricate designs or patterns. Forming, on the other hand, involves bending or shaping the coils using specialized machinery to create curved or contoured products. Finally, the shaped steel products are inspected for quality and undergo any necessary finishing processes such as painting or coating. This ensures that the products meet the required specifications and are ready for distribution or further assembly. In summary, steel coils are processed and shaped into specific products through a combination of steps including unwinding, flattening, cold rolling, annealing or galvanizing, cutting, stamping, forming, inspection, and finishing. Each of these steps plays a crucial role in transforming the raw steel coils into high-quality products used in various industries.
- Q: Is it just because brass is reloadable? But what makes it reloadable? What does brass bring to the equation that the steel cased ammo can't do?
- Ok folks, BOTH Brass and Steel work harden. That's what happens when you get into the plastic deformation part of the stress - strain curve. In the case of brass it can take significantly more deformation before it hardens than steel, steel can take significantly more stress before it goes into plastic deformation. Steel is unattractive in plastic strain environments because it has an unstable plastic deformation region before it stress hardens. Brass has much smoother performance. I don't know a heck of alot about making casings, but certainly for necked casings steel will wear out tooling much faster than brass. In a straight wall case it probably doesn't matter as much since it is just tubing. Typical Brass has a brinnell hardness of around 60, mild steel around 130. Steel is a LOT harder than Brass.

- Q: What are the challenges in coil leveling for coated steel?
- Coil leveling for coated steel presents several challenges that need to be addressed in order to achieve high-quality, flat, and smooth coils. Firstly, one of the main challenges is the potential for coating damage during the leveling process. Coated steel coils are typically coated with materials such as zinc or paint, which can be easily scratched or marred if not handled properly. The leveling process involves passing the coil through a set of leveling rolls, which can potentially cause friction, abrasion, or other mechanical damage to the coating. Therefore, it is crucial to carefully control the speed, pressure, and alignment of the leveling rolls to minimize coating damage. Secondly, the thickness variation across the coil presents a significant challenge. Coated steel coils often have thickness variations due to inherent material properties or production processes. These variations can result in uneven leveling and can lead to coils with waviness or uneven flatness. Achieving uniform leveling across the entire coil surface is essential to ensure consistent quality and appearance of the final product. Another challenge in coil leveling for coated steel is the possibility of coil shape distortion. Coating processes can introduce stresses into the steel, which can cause the coil to warp or distort during the leveling process. This distortion can result in coils with uneven edges or inconsistent flatness. Proper control of the leveling process parameters, such as the number of leveling passes and the tension applied to the coil, is necessary to minimize shape distortion. Additionally, the coil leveling process can generate internal stresses in the steel itself, particularly in coated steels that have been cold-rolled or heat-treated. These internal stresses can cause coil spring-back, where the coil tries to return to its original shape after leveling. Spring-back can result in coils with unwanted curvature or uneven flatness. Effective strategies, such as stress relief annealing or using counteracting leveling techniques, are essential to minimize spring-back and achieve the desired flatness. Finally, the handling and storage of coated steel coils present challenges in maintaining the quality of the leveled coils. Coated steel coils are sensitive to environmental conditions such as humidity, temperature, and exposure to corrosive agents. Proper storage and handling practices are crucial to prevent coating damage, rust, or other forms of deterioration that can occur during transportation or storage. In summary, the challenges in coil leveling for coated steel include minimizing coating damage, addressing thickness variation, controlling shape distortion and spring-back, and ensuring proper handling and storage. Overcoming these challenges requires precise control of process parameters, the use of appropriate leveling techniques, and adherence to strict quality control measures throughout the entire process.
- Q: I am doing a project on how revolvers work and what materials they use and would like to know what specific grade of stainless steel they use for the manufacturing of the frame and cylinder?
- *Rifle barrels are usually made from steel alloys called ordinance steel, nickel steel, chrome-molybdenum steel, or stainless steel, depending upon the requirements of the cartridge for which they are chambered. The higher the pressure and velocity of a cartridge (pressure and velocity usually go up together), the faster it will wear out a barrel. To give a satisfactory service life, barrels for high velocity cartridges must me made from tougher and harder steel than barrels for lower pressure cartridges. *The 400 (416) series SS commonly known as ordnance grade , is what barrels are made from . *If you want your barrel to be made from super alloy then it is 718 Inconel ,but a costly affair.
- Q: What is the process of pickling and oiling steel coils?
- To ensure the quality and protection of steel coils, a series of steps are undertaken in the process of pickling and oiling. The first step involves pickling, wherein impurities and scale are removed from the surface of the steel coil. This is achieved by immersing the coil in an acid bath, such as hydrochloric acid or sulfuric acid, which effectively dissolves any oxides, rust, or contaminants present on the surface. This step is critical as it readies the steel for further processing and safeguards against potential defects or corrosion. Following pickling, the steel coils are rinsed with water to eliminate any residual acid and then dried. Once they are clean and dry, a layer of oil is applied to provide temporary corrosion protection and lubrication during subsequent handling and transport. The oil coating acts as a barrier, preventing rusting or oxidation before the steel undergoes further processing or is utilized in various applications. The oiling process can be executed through various methods. One common approach is to apply the oil using a roller or brush, ensuring an even coating across the entire surface of the coil. Alternatively, the coils can be passed through a bath or spray chamber where the oil is administered. The choice of oil depends on the specific requirements of the steel and its intended use, with options ranging from mineral oil and synthetic oils to specialized rust-preventive coatings. Once the oiling process is complete, the steel coils are typically stacked, wrapped, or packaged for storage or transportation. It is crucial to handle the coils with care to avoid damaging the oil coating and compromising the corrosion protection it provides. Overall, the pickling and oiling of steel coils are indispensable steps in the steel manufacturing process. They ensure the quality, cleanliness, and protection of the steel, thereby prolonging its lifespan and enhancing its performance in various applications.
