Q:I know that they have steel shot in smaller sized pellets....say, number 4 shot. I guess it's for waterfowl, etc.Do they make steel buckshot? If not, why not? Would the pellets be too heavy? Wouldn't they have excellent penetration ability?: This Site Might Help You. RE: Do they manufacture steel buckshot? I know that they have steel shot in smaller sized pellets....say, number 4 shot. I guess it's for waterfowl, etc. Do they make steel buckshot? If not, why not? Would the pellets be too heavy? Wouldn't they have excellent penetration ability?

Q:Is steel cut really better? The nutritional profiles are nealy identical. Which one has the best flavor??Thanks!: The biggest difference, is steel cut oats tend to be a European way, and Rolled oats are more North American, Irish and Scottish Oats tend to be steel cut, take longer to cook as the germ and whole grain is almost shredded, where with rolled oats it is process to were only a portion of the bran remains, that is why you can by Oat Bran in North America. We have instant, quick and large flake from Quaker, all cook in a matter of between 2-10 minutes, steel cut can take up to 25-30 minutes and do better in a double boiler, my mother tells a story were her grandmother would prepare it at night and let it sit on the back of the wood stove all night for breakfast the next day.

Q:Can steel coils be coated with aluminum?: Yes, steel coils can be coated with aluminum through a process called coil coating.

Q:How are steel coils protected during transportation?: Steel coils are kept safe and free from harm during transport through a range of precautionary measures. One widely used technique involves utilizing top-notch packaging materials like heavy-duty plastic wrap or waterproof paper. These materials form a protective shield against external factors such as moisture, dust, and debris. Moreover, steel coils are typically placed on wooden pallets or skids to elevate them from the ground and prevent direct contact with surfaces that may cause scratches or dents. To provide further protection, the coils are securely fastened to the pallets using strong, corrosion-resistant metal strapping or bands. This ensures that the coils remain in position and do not shift or move during transport, significantly reducing the risk of damage. Additionally, specialized equipment like coil cradles, coil racks, or coil bunks are used to load and secure the steel coils onto flatbed trailers or shipping containers. These devices are specifically designed to firmly hold the coils in place and evenly distribute their weight, preventing any stress or strain during transit. Apart from physical safeguards, steel coils may also undergo various surface treatments before being transported to prevent corrosion. This may involve applying a protective coating or oiling the coils to create a barrier between the steel and the surrounding environment. This process is particularly important when the coils are exposed to adverse weather conditions or long shipping durations, as it helps to prevent rust or other forms of corrosion. In conclusion, a combination of appropriate packaging, secure fastening, and proper loading techniques are employed to ensure the safety of steel coils during transportation. These measures guarantee that the coils arrive at their destination without significant damage.

Q:How are steel coils used in the production of steel tanks?: Steel coils are used in the production of steel tanks by being cut and shaped into the desired size and shape of the tank. These coils are typically made of high-quality steel, which provides strength and durability to the tanks. The coils are processed through various manufacturing techniques like rolling, bending, and welding to create the tank's body, ensuring a seamless structure. Additionally, the coils can also be used to create the tank's base, lid, and other components, resulting in a complete and sturdy steel tank suitable for various applications.

Q:I have a set of steel pans with copper bottoms. When I cook with oil it always burns the oil to the pan and takes days to clean. I don't think I should use steel wool, since it might scratch the surface. Does anyone know a faster way to clean scorched oil off a steel pan?: Get a can of Barkeeper's Friend. It's a powdered cleanser. It's gentle enough to be used on a ceramic cook top but still strong enough to get metal clean. Cheap and made from rhubarb leaves! Dampen the pan with water, sprinkle generously and smear around with a sponge with one of those non-stick safe nylon scrub pads. Wait about 10-15 minutes to let the product do some of the work for you. Come back and give it a good scrub. Reapply if necessary. I have all stainless steel cookware and use the Barkeeper's to keep them looking nice; especially since they are on display with my pot rack. I also have some copper pieces used for decoration and I use the Barkeeper's to keep them looking nice. It cleans them up faster and better than any of the homemade concoctions or metal cleaners without the residue. And I do use it on my ceramic cook top too! Be sure to wash and rinse the pan after you get it clean; it does leave a haze if you don't.

Q:Which one would be stronger? And should damascus steel be tempered?Thank You: Damascus steel is not a good choice. Gun barrels were once made of Damascus but no longer. Mono steels have come a long way in the past 100 years along with methods of tempering. The skill required to create a functional, strong, and safe Damascus steel sword is rare and extremely labor intensive. A cheap Damascus sword should never be used for cutting anything but air. While you can buy a fine Damascus sword expect to pay a high price. Although any fine sword will cost quite a bit, $500 to thousands. Modern Mono steels now out perform even traditional folded blades. Folding was to change the carbon content and not primarily for strength. Lots of info on the web, make sure to check it for yourself and don't believe the romantic notion that antique blades out perform anything made today. That's just not true.

Q:Will a 8mm steel ball fired from a 150lbs crossbow kill small game and if so, from how many yards?: People usually compare regular fiber stringed crossbows with the string in steel ball crossbows. steel ball crossbows shoot with steel cables that can take the light weight of the ball . On top of that they are ALLWAYS have cams that reduce the tension when releasing the ball. I own a 160 lbs crossbow that shoots both bolts and 8mm balls and I love it, it can take a raccoon , a rabbit , even a turkey and it is very easy to reload since it keeps several balls in the magazine. About how accurate it is , as most shooting weapons it is a matter of practice. I have a pistol 6 mm balls and is really fun, I don't think you can kill much with that one but it is fun to shoot at around the house. I would give it a try , you might be pleasantly surprised.

Q:Maybe it is obvious. But i have thought alot about it.I thought steel at a cool temperature was unbreakable. I am not one for science or physics or engineering (i am a political science major). But i don't understand why the planes that struck the world trade center on 9-11 didn't just dent the side and fall,How did the place break the steel? Was it the velocity? Is steel easily broken?I realized that i wasn't taught how the planes broke the steel, and that no one ever asked. I searched the web and i couldn't find the answer or even anyone who had asked the question before.(i don't care about conspiracy theories, i just want scientific facts): steel is not unbreakable. the world trade centers had a steel infrstructure, but were mostly glass and materials with many other flaws. steel is not the top of the rocwell scale(materials rated by thier hardness) when the planes impacted the outside of the buildings, you have to take into account that the planes skins and infrastructure where made of aluminum(too keep weight down) so once the outer skin of the planes was breached, you have to account for the heat created by burning fuel, friction, and the momentum of a vehicle that weighs tons hitting an immovible object. just keep in mind that if you propel a piece of straw at an proper speed, you can have it impale a full grown palm tree

Q:What is the thickness range of steel coils?: The thickness range of steel coils can vary depending on the specific application and industry requirements. However, generally, the thickness range of steel coils can range from as thin as 0.005 inches (0.13 mm) to as thick as 0.5 inches (12.7 mm) or even more.
