Q:where can you find carbon steel in los angeles?? what store?? preferabbly 01 carbon steel: All steel has carbon in it, usually less than 1%. The fancy steels that have enough other elements mixed in are generally called alloy steels. So, carbon steel usually refers to the most basic cheap steel. A36 is a kind of carbon steel that meets specific standards of the A36 specification. I don't know what 01 carbon steel is. Steel is available all over Los Angeles so just look in the phone book yellow pages under steel or metal. If you are near El Monte, my favorite place is Industrial Pipe and Steel, lots of cheap scrap, used machinery, and a huge industrial hardware store built right in. There is a place in Gardena called MK Metals. There's a great place just north of the Burbank airport (can't remember the name) and one in Harbor City called Action Metals (big on recycling). No sense driving all over. Just check the phone book. Two very common carbon steels just go by the terms hot rolled and cold rolled. Hot rolled is the cheapest and softest and still has the mill scale attached so the surface is a little rough and uneven, but this is by far the most commonly used. Cold rolled (usually the AISI 1018 grade) has been work hardened and rolled flat and smooth. It's slightly more expensive but stronger and prettier. If you are going to cut away some of the thickness and you want the steel to remain flat, you probably want hot rolled steel because sometimes the cold rolled steel (CRS) will warp. It does that because the steel is already prestressed from the cold rolling process and when you cut away some of the pre-stressed material the forces holding the material flat are no longer balanced.

Q:Why can't you use a lead shot only choke with steel shot or a steel shot only choke with lead shot? I have used a lead only choke with steel shot and my shotgun shot fine and there was no damage to the choke.: You should not have done this. It not a matter of shooting fine - it's a question of getting the correct distance and shot pattern SAFELY. Lead only chokes squeeze the lead shot a considerable bit. Lead is compressive and soft - it takes more squeeze to get the correct patterns from a shotgun. Steel only chokes do not squeeze as much as the lead version because the steel is very had and does not compress well. When you accidentally shoot lead through a steel chock the pattern will be weird. But, it usually is not an unsafe condition. However, steel through a lead choke will cause unsafe pressure at the choke and can explode. You end up with a bugs bunny/road runner cartoon looking shotgun! Most gun shops all over the USA are decorated with these blown up shotguns from people doing exactly what you did. Unless you want to add yours to the other dead gun collection in some shop - I recommend you take your shotgun and all your chokes into a gun smith and have him look it all over. See if anything is out of tolerance. Guns are not fool proof. If you do not follow the instructions and operate them safely they will blow up and tear a piece of your body off. Just ask any ER doctor or long time shooter.

Q:What is the typical size and weight of a steel coil?: The typical size and weight of a steel coil can vary depending on the specific application and industry. However, in general, steel coils are typically manufactured in widths ranging from 0.5 to 2 meters (1.6 to 6.6 feet) and can weigh anywhere between 1 to 25 metric tons (2,205 to 55,116 pounds). The exact size and weight of a steel coil will depend on factors such as the type of steel used, the intended use of the coil, and the manufacturing process employed.

Q:Steel seems to be much less expensive. What is the reason why? I've heard steel will ruin a barrel after time....is that true? But with the price difference maybe it don't matter? Is steel reliable? What are the negatives about steel I should know before buying?: Steel is a cheaper material than brass. Simple as that. Steel is harder than brass as well so it can cause wear on the chamber and bolt at a faster rate. What some places do it's not pure steel but they mix in other softer metals to make the casing softer so it's not as much as issue as people make it out to be. People tend to dislike steel cased ammo as well due to it running dirtier and the coating on the casing gumming up the insides. But these people from my experience do not clean their guns. Ever. And then when they start to act up they wonder why.

Q:What is the most common bullet resistant steel that is used, can certain bullets just not be stopped, also what type of glass is bullet resistant or is that special made.: any amount of steel, you can find a bullet or cannon big enough to go through it. The WWII battleships had 12 inches of steel, but a torpedo would still put a hole in that. Any bullet, on the other hand, and you can find a thick enough steel to stop it. It's just that the steel may be too heavy to be useful. .

Q:Can steel coils be coated with impact-resistant materials?: Yes, steel coils can be coated with impact-resistant materials. The coating process involves applying a layer of impact-resistant material onto the surface of the steel coils to enhance their durability and protection against impacts or damages. This coating can provide additional strength and resistance, making the coils suitable for various applications requiring impact resistance.

Q:I have heard using the BRASS casing is the best thing for an AR-15? Should i just use Brass or Steel?: Unfortunately, steel case ammo being actually harmful for your AR is a quite popular myth. Steel is less malleable than brass. When you fire a brass cartridge, the brass expands to the chamber walls and helps block any expanding cases from dirtying up your chamber. When firing steel cartridges, the steel doesn't expand as well as brass, so you probably will end up getting a little carbon residue in the chamber. This tiny amount of carbon in the chamber is enough to make extraction of brass cased ammo more difficult. When the brass expands to the dirty chamber after firing steel ammo, it conforms to the carbon residue somewhat, increasing friction. This small amount of friction is sometimes enough to make a normally okay AR malfunction when attempting to eject a fired cartridge. So to give you a short answer, use both! Just make sure to really clean out the chamber after firing steel ammo.

Q:Can steel coils be coated with polymer?: Yes, steel coils can be coated with polymer.

Q:what do we use steel for and whyand why do we use brass for instrumentsplz help its homework and i cant find the answer anywhere : (: Brass and steel are type of metals that mostly use for moist area and also have luxury used cause of ability of shine .Steel definitely is for anti oxide ,mostly use in area that food and liquid such as acid ,milk ,soda,water are in contact .Brass most use for electric parts and decoration for ability of conductivity and shin .

Q:How are steel coils used in the production of industrial shelving?: Steel coils are used in the production of industrial shelving as they are typically cut and shaped into various components, such as uprights, beams, and braces, which are then assembled to create sturdy and durable shelving units. The coils provide the necessary strength and stability required to support heavy loads and withstand the demands of an industrial environment.
