Q:i mean cor ten steel( rusted)
Bill summed it up pretty quick and provided a link. For some reason you are focusing on the copper content when it really is insignificant in the overall picture of the sun hitting its surface. If you could elaborate more, maybe we could offer a better answer.
Q:
There are several different coil leveling machine configurations used for steel coils, depending on the specific requirements of the application. Some common configurations include single-leveler machines, which use a set of leveling rollers to reduce the coil's thickness variations; double-leveler machines, which employ two sets of leveling rollers for enhanced precision; and stretch leveling machines, which utilize a combination of roller leveling and tension to remove coil shape defects. These configurations can be further customized with additional features such as coil feeders, crop shears, or edge trimmers, depending on the desired end product and production requirements.
Q:
Steel coils are an essential component in the production of transportation systems as they are used to manufacture various parts such as car bodies, chassis, and other structural components. These coils are shaped and processed to create different forms of steel, which are then used in the construction of vehicles like cars, trucks, trains, and ships. The durability and strength of steel make it an ideal material for transportation systems, ensuring safety and reliability.
Q:
There are several types of steel coil packaging techniques, including banding, strapping, shrink wrapping, and palletizing. Banding involves securing the coil with metal bands, while strapping uses plastic or steel straps. Shrink wrapping involves wrapping the coil with plastic film and applying heat to shrink it tightly. Palletizing involves stacking the coils on a pallet and securing them with stretch wrap or straps. These techniques help protect the coils during transportation and storage.
Q:
There are several methods of forming steel coils, including hot rolling, cold rolling, and continuous casting. Hot rolling involves heating the steel above its recrystallization temperature and passing it through a series of rollers to shape it into coils. Cold rolling, on the other hand, involves reducing the thickness of the steel by passing it through rollers at room temperature. Continuous casting is a process where molten steel is poured into a mold and then cooled and solidified into coils. These different methods offer varying levels of strength, durability, and surface finish in the resulting steel coils.
Q:I have good quality knives that I sharpen with various things, but mostly with a fine, diamond encrusted dry stone (eze lap) . When I run them over the steel, it doesn't seem to make any difference. I've heard that it aligns the edge, whatever that means. Using a steel, is it all just for show ?
It does NOT sharpen a knife, It helps to keep a sharp knife sharp. Once you have sharpened your knife weather on a stone or other ways you should use the steel before using each time to keep it's edge . Think of an athlete who works out to gain muscles(sharpening) and stretches(steel) before using them. The show part is all in the way you use the steel, some just go downward and some go upward, either way you need to change sides of the blade on each stroke just like sharpening.
Q:Correct me if I am wrong, but steel is an alloy between iron and carbon. Does the carbon in the steel stops the iron from rusting or corroding? Also what is the difference between mild steel and stainless steel?
Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
Q:so why shouldn't one use a steel cased 223 in an ar15?
Steel cased ammo doesn't obturate (expand against the chamber walls) when fired as well as brass cased ammo does. This allows carbon to build on the chamber walls. Leading to failure to extract. But if you can get steel cased ammo for cheap, shoot it up! Just have a cleaning rod with when you shoot. If tapping the butt on the ground doesn't dislodge the spent case, push it out with the rod. Be sure to use a chamber brush when you clean your rifle after shooting steel cased ammo. I would never use steel cased ammo for defensive purposes in an AR however. The occasional failures to extract make it a bad idea. It's plinking ammo only.
Q:
Stainless steel coils are commonly used in various industries such as automotive, construction, manufacturing, and food processing. They are utilized for making a wide range of products including kitchen appliances, metal containers, piping systems, heat exchangers, and architectural components. The high corrosion resistance, durability, and aesthetic appeal of stainless steel make it an ideal material for these applications.
Q:I have some steel wool and a charged 9V Battery, when I connect 2 wires to the battery, then touch the wool with the ends of the wires the wool instantly starts burning, but when I connect 2 wires to the piece of steel wool (a new piece not same one of course) and touch the battery with the ends of the wire nothing happens (see image...)
What's happening in the first case is that the initial contact of the wire to the steel wool is not very good and there is a high resistance as the touch is made and there is probably a slight spark that starts the steel wool burning. Now it is even harder to make good contact and the process continues. In the second case there is initially a good contact to the steel wool and there is no spark when the circuit is completed at the battery. It would be difficult to cause the heating and the spark at a distance unless you had a way to remotely cause the wire to lightly touch the steel wool. A gas lighter which uses a flint to create a spark is good for igniting a gas burner which will continue to burn by itself, but probably wouldn't cause the steel wool to burn without the energy coming from the battery to keep it going. Steel wool WILL continue to burn if it's in a pure oxygen atmosphere. You might try hooking the battery up to the steel wool as in the second case and using a spark lighter to start some burning close to one of the wire connections to see if the extra battery power might keep the burning going.
