- Q: I am wondering what the highest quality steel is used in handgun production.
- The first answer was correct. The type of steel used in most blued handguns is the highest. After that I prefer stainless. Then the Scandium framed pistols.
- Q: How are steel coils used in the production of metal partitions?
- Steel coils are an essential component in the production of metal partitions. These coils are typically made from high-quality steel and serve as the raw material for manufacturing the partitions. Firstly, the steel coils undergo a process called slitting, where they are cut into narrower strips of the desired width. This enables manufacturers to customize the size of the metal partitions according to specific project requirements. After slitting, the steel strips are then fed into a roll forming machine. This machine gradually shapes the strips into the desired profile for the metal partitions. The roll forming process involves passing the steel strips through a series of rollers, which progressively bend and form the metal into the desired shape and dimensions. Once the metal has been formed into the desired shape, it is cut into appropriate lengths to create individual partitions. These partitions are then further processed, such as through welding or spot welding, to join different components together and enhance their structural integrity. Steel coils are preferred for metal partition production due to their strength, durability, and versatility. The use of steel ensures that the partitions can withstand heavy loads, resist corrosion, and provide long-lasting performance. Additionally, steel coils offer a high degree of design flexibility, allowing for the creation of various partition styles, such as solid panels, perforated screens, or mesh partitions. Overall, steel coils play a crucial role in the production of metal partitions by providing the necessary raw material, strength, and customization options required for these versatile architectural elements.
- Q: What is the average cost of shipping steel coils?
- The average cost of shipping steel coils can vary depending on various factors such as the distance, weight, size, and mode of transportation. It is recommended to obtain quotes from shipping companies or freight forwarders to get a more accurate estimate based on your specific requirements.
- 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?
- When 9mm was short I bought some steel Tula ammo, it was cheap and available. When at the range I was shooting it and it sounded different and felt different, way less kick. So I loaded up a mix of Tula and some Federal. Big difference between them. I also had failure to eject on the steel, then put brass in and did not have that problem. I do not buy cheap steel ammo anymore.
- Q: How do steel coils contribute to the automotive manufacturing sector?
- Steel coils are essential in the automotive manufacturing sector as they are used to produce various components such as body parts, frames, and suspension systems. The high strength and durability of steel coils make them ideal for ensuring the safety and structural integrity of vehicles. Additionally, steel coils are easily moldable, allowing manufacturers to create complex shapes and designs, contributing to the overall aesthetics and functionality of automobiles.
- Q: what is the difference between stainless steel 304 (AISI 304) and stainless steel 310 (AISI 310) COR-TEN A
- Weathering steel will rust, but the rust will be adherant and not flake off and be replaced by new rust. Therefore once it rusts it will pretty much stop rusting any more. One (severe) down side is that anything around it will be streaked with rust stains and it will look awful. Some bozo with the Texas Department of Transportation designed a number of freeway interchange overpasses here in Houston using Cor-Ten steel and all of the concrete supports are streaked with red rust stains and it looks like hell. Cameron built an office building here in Houston with a Cor-Ten facade and it is streaked with rust too. They should have gone ahead and spent the money and painted them, but they didn't.
- Q: Does anyone know if there is any info on Steel Manufacturing techniques, utilyzing electro/mechanical methods in order to create carbon nanotubes from the %C already inherant in the steel. In other words just modifying the Geometry of the Carbon the already makes up some of the steel.
- I don't think that would work. First off, there's not enough carbon in steel - even very high carbon steels are only about 2% carbon. Second, the iron atoms in steel form a crystal lattice, in the shape of a cube, with another iron atom in the middle of the cube. Each cube is about 0.3 nm per side. Carbon atoms work their way into the crystals and displace the iron atoms. But a carbon nanotube is around 1 nanometer in diameter - that's 3 times as big as the iron lattice! So a nanotube wouldn't fit. One thing you might do, however, is make a composite - mix the materials together on a scale a little bigger than the atomic scale that the iron and carbon mix to make steel. Just like a carbon fiber bicycle frame or ski pole is strands of carbon (much bigger and not as strong as nanotubes) held together with epoxy, you could hold nanotube strands together with metal. Not sure it would be good for armor, but if you can figure out a way to do it, I'm sure someone will come up with a use for it!
- Q: I'm assuming that brass is flexible, expands and then bounces back to it's original shape. But if aluminum and steel expand and don't contract wouldn't they cause guns to jam more often for example?
- Steel is magnetic, and can spark...Sparks are not good things around gun powder....CCI loads some pistol rounds with aluminum cases, but they are not re loadable, as the aluminum is so soft the primer pockets will wear out quickly..Aluminum, metallurgical, has a valence of +3, which means that moisture would cause electrolysis to set up between the steel primer cup and the aluminum case, which would pit the primer pocket...Steel is harder than brass, and would not uniformly expand on the firing sequence, and would be likely to rupture instead of expanding and sealing...Also, the hardness of steel would make resizing cases difficult, as steel needs to be heated before reshaping.......Hope this helps....
- Q: case hardening steel is adviced or thru hardening steel is most suitable?
- I don't know your application, but here is some advice. Case hard provides a hard shell around soft steel, depending on the bake, the case is usually .002-.008 thick. (thousands of an inch) Heat treated steel or tool steel is hard all the way thru. Case hardening, provides toughness with flexibility, however, once it's compromised, the part is scrap. Hardend tool steel is extreemly hard throughout and the harder it is, the more brittle it becomes. The application of the part will help you to determine the material needed. For instance; Plastic injection molds are very hard so the hot plastic wont erode them over years of use. Punch Press dies aren't as hard but are tougher to withstand the shock. Machine bolts are case hardened so they can last, but soft enough to allow some stretching during tightening. Either way, the time in mfg will be about the same. Most tool steels today cut like cheese, but take time to be heat treated. Tool steel will cost a bit more than low carbon steel. Low carbon steel is as machinable, and cheaper, but, again, the baking period is as long or longer than tool steel. There are a lot of materials on the market today that maintain the durability of heatreated steel without having to go thru that process. 4140, ( or chrome/moly) comes to mind. There are also some 400 series stainless that work as well, and others. You need to determine strength, flexibility, ease of mfg, cost and repairability when considering which steel to use.
- Q: Does aluminum or steel hold up better? We found a steel for 1/2 the price of aluminum, obviously its heavier but any other downsides? rust faster ect? also, does anybody know, in PA do you pay sales tax on trailers? and do dealers normally give you license plates to get the trailer home with? we live 3 hours away from the dealer so thats why i want all details :) would stink if i messed up!!
- I bought a steel trailer. It was much heavier than the aluminum, as you said. But really, they are equivalents. As long as you have enough power to haul the trailer, you can use steel. We never had a rust problem with ours. In PA you do pay sales tax on horse trailers, stock trailers, etc. I forget about the plates, though. It's been a few years since we got our trailer. I would assume they would give you something to get the trailer home with though.
