Q: How are steel coils inspected for bendability?: Steel coils are inspected for bendability through a combination of visual examination, mechanical testing, and dimensional analysis. Visual inspection involves identifying any visible defects such as cracks, dents, or surface irregularities that could affect the coil's bendability. Mechanical testing is conducted to measure the coil's resistance to bending and evaluate its flexibility. This includes performing bend tests to determine the coil's ability to withstand a specified degree of bending without breaking or cracking. Additionally, dimensional analysis is performed to ensure that the coil meets the required thickness, width, and length specifications, as these factors also impact its bendability.

Q: What is the minimum temperature that steel coils can withstand?: The minimum temperature that steel coils can withstand depends on the specific grade of steel and its intended application. However, in general, most steel coils can withstand temperatures as low as -40°C (-40°F) without significant damage or structural failure.

Q: I am looking at website on google based on the terms structural steel fabrication and simply steel fabricationI know that there must be a difference between the two terms, but it seems that many website authors use the two terms interchangeably.Do you know the key differences between the two terms?: Structural steel is steel construction material, a profile, formed with a specific shape or cross section and certain standards of chemical composition and strength. Structural steel shape, size, composition, strength, storage, etc, is regulated in most industrialized countries. Fabrication, when used as an industrial term, applies to the building of machines, structures and other equipment, by cutting, shaping and assembling components made from raw materials. Small businesses that specialize in metal are called fab shops. Steel fabrication shops and machine shops have overlapping capabilities, but fabrication shops generally concentrate on the metal preparation, welding and assembly aspect while the machine shop is more concerned with the machining of parts.

Q: Can steel coils be rewound?: Yes, steel coils can be rewound. Rewinding steel coils involves uncoiling the existing steel coil and then recoiling it to the desired specifications. This process is commonly done to adjust coil size, improve coil shape, or remove defects in the original coil. Rewinding steel coils allows for better quality control and ensures that the coils meet the specific requirements of the customer.

Q: How are steel coils shaped into specific forms?: Steel coils are shaped into specific forms through a process called cold forming or cold rolling. This involves passing the steel coil through a series of rollers that gradually shape and form it into the desired shape, such as sheets, strips, or tubes. The precise dimensions and specifications of the final form are achieved by adjusting the pressure and alignment of the rollers.

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 wondering if steel casings are bad for a 1911. I know that an AK-47 will eat up steel casings all day long, but steel casings are bad for, and can be hard on an AR-15. I only have brass for my AR and that will never change. I'm curious as to how a 1911 fairs with steel casings. Is it bad for the gun or does it not matter? I'm asking because steel cased rounds seem to be the only readily available ammo these days. Thanks: This better placed in the hunting section of sports. That is the area for gun questions. I've never used that Russian stuff in my guns. I would stick with brass or Aluminum Blaser ammo.

Q: y does 1095 steel on a katana weight about a pound less for the same amount than 1045? the 1095 is better right? but then why is 1045 steel more comenly used for practical use than 1095, even though i no its cheaper to use 1045 for tami mats. so is 1095 steel the better investment for buying and minor tami mat use?: 1045 is a medium carbon steel is used when greater strength and hardness is desired than in the as rolled condition. Extreme size accuracy, straightness and concentricity combine to minimize wear in high speed applications. 1095 is a high carbon steel, but does not hold as sharp an edge. 1095 high carbon steel is harder and more durable than 440C stainless steel, but will rust much more easily. Stainless steel is more brittle than both 5160 and 1095 carbon steel, but is still very useful due to its resistance to rust and corrosion.

Q: How do steel coils perform in corrosive environments?: Steel coils typically perform well in corrosive environments due to their inherent resistance to corrosion. This is primarily because steel is an alloy composed of iron and other elements, such as carbon, which provides it with a protective layer known as a passive film. This passive film acts as a barrier between the steel surface and the corrosive elements, preventing direct contact and thus minimizing the risk of corrosion. In addition to the passive film, steel coils can also be coated with various protective coatings to enhance their resistance against corrosion. These coatings, such as zinc or epoxy, provide an additional layer of protection and further extend the lifespan of the steel coils when exposed to corrosive environments. However, it is important to note that the performance of steel coils in corrosive environments can still be influenced by factors such as the specific corrosive agent, exposure duration, and the presence of other contaminants. In highly aggressive environments, such as those with high humidity, saltwater exposure, or acidic chemicals, the protective layers on steel coils may deteriorate over time, leading to potential corrosion. To ensure optimal performance in corrosive environments, it is advisable to select steel coils with corrosion-resistant properties, such as stainless steel or galvanized steel. Regular maintenance and inspections are also crucial to identify any signs of corrosion early on and take appropriate measures to prevent further damage. Overall, steel coils offer good resistance to corrosion in most environments, but the severity of the corrosive conditions can ultimately impact their performance.

Q: What is the use for spring steel that take advantage of its unique properties?: The primary use is for springs. It can be deflected to a large extent by applying a force it will return to its original shape when the force is removed. The force/displacement relationship tends to be a constant. A lesser use is to use spring steel wire as a vibrating string on a stringed instrument.
