Ultimately, the choice of coil edge depends on personal preferences and desired sleeping experience.

Q:I'm kind of confused as to how the difference between a stainless steel and blued steel firearm is sometimes only $20 or so. Isn't stainless steel fairly more expensive to manufacture than plain carbon steel? Are some stainless steel firearms simply stainless steel finished with carbon steel underneath?

No, there are no rifles produced that are carbon steel underneath with a stainless steel finish. Typically, gun prices are set by whatever people will pay for the finished product, NOT based on what the material costs actually are. Even if the stainless were CHEAPER to produce, manufacturers could still charge a premium on those products because it offers an advantage to the user (less maintenance). Stainless is seen as an upgrade because of the maintenance and the good looks, so it's like an upgrade option on a sports car, even if it doesn't improve actual performance, it improves the marketability for the product, so it increases the product price. For rifle barrels, many manufactures do NOT charge a high mark up for stainless steel because even though YES is is harder to machine, they don't have to blue the part, which is an extra processing step, and extra materials cost. So when a stainless steel blank is made, it is machined, washed, and finished, but a chrome-moly barrel much be machined, washed, prep'd, hot blued, and finished.

Q:How are steel coils inspected for flatness?

Steel coils are inspected for flatness using various methods, such as visual inspection, measuring the crown or center buckle, and conducting a straight edge test. These techniques help assess any deviations or unevenness in the coil's surface, ensuring that it meets the required flatness standards.

Q:What are the different methods of coil end welding for steel coils?

Steel coils can be welded together using various methods. Some of these methods include: 1. Resistance Welding: By applying an electric current to the coil ends, the heat causes them to melt and join. This method is popular for its efficiency and speed. 2. Laser Welding: A high-energy laser beam is used to melt and fuse the coil ends precisely. This technique ensures high-quality welds. 3. Tungsten Inert Gas (TIG) Welding: TIG welding creates a protective atmosphere around the welding area using a non-consumable tungsten electrode and an inert gas like argon. It produces clean and strong welds, making it suitable for steel coil end welding. 4. Plasma Arc Welding: This method involves using a plasma torch to create an electric arc between the electrode and the workpiece. The intense heat generated melts the coil ends for welding. 5. Electron Beam Welding: A high-velocity beam of electrons heats and melts the coil ends. This technique is used for thick steel coils and offers deep penetration and high welding speed. 6. Friction Stir Welding: By using a rotating tool to generate friction and heat, the coil ends soften and fuse together. Although commonly used for joining aluminum coils, it can also be applied to steel coils. These are just a few examples of the different methods available for welding steel coil ends. The choice of method depends on factors such as desired weld quality, production speed, material thickness, and application requirements.

Q:What are the common thicknesses available for steel coils?

The specific requirements and applications determine the available common thicknesses for steel coils. However, various industries commonly produce and use certain standard thicknesses. Typically, steel coils can range in thickness from 0.005 inches to 0.5 inches or more, depending on the type of steel and its intended use. For instance, in automotive manufacturing, where steel coils are utilized for body panels and structural components, the thicknesses commonly range from 0.5 mm (0.020 inches) to 3 mm (0.118 inches). In the construction industry, steel coils are employed for roofing, siding, and structural framing. The common thicknesses can vary from 0.014 inches to 0.062 inches, depending on the specific application and structural requirements. Similarly, appliances manufacturing, such as refrigerators, washing machines, or HVAC systems, frequently employ steel coils with thicknesses ranging from 0.018 inches to 0.035 inches. It is important to note that these are only a few examples of common thicknesses, and variations can occur based on the specific requirements of different industries and applications. Custom thicknesses can also be produced upon request to meet unique needs in various sectors.

Q:Hi,Well, I live near almost across the street from a forest, and my neighborhood is full of raccoons!!! Recently, I just purchased a bunny and have kept it at my cousin's house for the time being. He has a steel cage, and is about 6 months old. I am considering bringing him home and leaving him in the back yard with his steel cage. I am just afraid that raccoons can bite through the steel and get to him. So the question is... Is is possible for raccoons to bite through steel? Btw,Please don't answer hate comments about me being a bad rabbit owner. I simply want to know if raccoons can bite through steel. If it doesn't work out, the rabbit will stay at my cousins house until further notice. But please, I did not waste 5 points for unneeded answers. Thanksss!

Well the raccoons can't bite through steel unless it is very thin steel, like aluminum foil thickness. But they have long arms and can reach into the cage so that would be my worry. They are also very clever so I don't know if it is safe for the bunny. That would depend upon the size of the cage and how hungry the raccoons are. The raccoons might be tempted to try to steal the bunny's food so that is a concern. Check with a pet shop owner or forester or someone like that who has knowledge about raccoons in the area.

Q:I feel really stupid asking this question but i feel like a put metal/steel strings on my classical guitar how do you tell the difference?

you do NOT want to put steel strings on a nylon string guitar, it will ruin it. It does get a little confusing. With steel strings, all 6 strings are metal. (usually steel, but not always, nickel, copper may be used too) And they use a steel core. with nylon strings, the high 3 strings, are obviously nylon/plastic. the 3 bass strings look metal, but they have a silk type core, with metal wrapped around it. The steel strings have a LOT more tension,, they can break the plastic tuners, beak the nut, pull the top up, and pull the bridge off, If you're not sure yet, have a real music store explain it, not a toy store, or costco or walmart.

Q:What are the different coil winding methods used for steel coils?
