Q: Can a steel at 0.0055 of thickness still be powerful enough to bash skulls? As well as stop handgun cartridges or at least weaken them?You see, i had an idea of making a cylindrical Knuckles made from steel. By my dimensions, 5in diameter, 12 inch h1 and 15 in h2. Half-Sphere: a sphere that is cut in half for the dome at the fist:( [ pi x ( d ^ 3) ] / 6 ) / 2Cylinder: I don't follow your calculations. It seems to me that the piece you show could be made from .01 steel and still be less than a pound. Also, it is hard to get steel thinner than .015 because anything thinner is not very useful. If you made it out of .015 steel and used a high strength steel, it might be useful. You wouldn't be bashing any skulls, but with some spikes on the end, it could do some damage, and protect against knives or other hand weapons. You also won't get any bullet resistance out of anything that thin. If you want to bash skulls and deflect bullets, you have to get up to at least .10 and several pounds. Any weight on your hands slows down the speed of your punch, but this is compensated for by the increased energy of impact carried by the extra mass. Also, having something hard to protect your hands allows for harder hits and more damage to the opponent. An interesting idea, but it would take some testing to figure out the optimum configuration. One problem I see is that it completely encloses the hand, making it impossible to use the hand for anything else. So you would have to put it on and take it off a lot, and there would be cases where you wouldn't be able to put it on when you needed it. For that reason, I would not wear two at one time. I would make it heavier and wear it on one hand for bashing skulls and deflecting weapons, and keep the other hand free for other things.

Q: What temp does fire have to be to melt steel?: more than 300° F

Q: What are the common methods of painting steel coils?: Painting steel coils can be done using various methods, depending on specific requirements and desired outcomes. Below are some commonly used techniques: 1. The most frequently employed method for painting steel coils is coil coating. It involves applying a layer of paint to the coil's surface before it is formed into its final shape. The coil is initially cleaned and treated with chemicals to ensure proper paint adhesion. Various techniques, such as roll coating, spray coating, or dip coating, are used to apply the paint. Finally, the coil is cured in an oven to ensure the paint dries and adheres correctly. 2. Electrostatic painting is another method where an electrostatic charge is used to apply paint to the steel coil. After cleaning and pre-treatment, an electrostatic charge is applied to the paint particles. These charged particles are attracted to the grounded coil, resulting in an even and efficient paint application. This method is commonly used for high-performance coatings due to its excellent coverage and adhesion. 3. For applications requiring a durable and long-lasting finish, powder coating is a popular method. Dry powder paint is electrostatically applied to the coil's surface. The powder adheres to the coil due to the electrostatic charge, and then the coil is heated in an oven to melt and cure the powder, creating a smooth and protective coating. 4. Spray painting is commonly used for smaller steel coils or touch-up applications. A spray gun is used to apply the paint in a controlled and even manner after the coil is cleaned and pre-treated. This method allows for precise control and customization of the paint application. The choice of painting method depends on factors such as desired finish, durability requirements, cost considerations, and the specific application of the steel coil. Each method has its own advantages and limitations, so it is crucial to select the most suitable one based on the project's specific needs and constraints.

Q: I'm not really sure if carbon steel is considered a metallic material.: Carbon and iron are both metallic.... so yes. You leave the iron laying in the forge - and it soaks up carbon atoms from the charcoal - so that as the steeling process goes on, the original iron becomes harder and harder.

Q: How are steel coils used in the production of electrical devices?: The production of electrical devices heavily relies on steel coils. These coils, typically made from high-quality steel, are precisely wound into a circular shape. They have a crucial function in various electrical devices, including transformers, motors, generators, and inductors. Transformers, for instance, heavily rely on steel coils. These devices are essential for adjusting voltage levels in electrical circuits. They consist of two separate coils, the primary and secondary coils, which are wound around a magnetic core. The steel coil plays a vital role in providing stability and support to the windings, ensuring proper alignment and preventing any deformation. Moreover, the high magnetic permeability of steel helps enhance the efficiency of energy transfer between the coils. In motors and generators, steel coils are utilized to create magnetic fields that either generate mechanical energy or convert it into electrical energy. These coils are wound around an armature or rotor, which rotates within a magnetic field created by a stator. As the current flows through the coils, a magnetic field is produced, resulting in the rotation of the armature or the generation of electrical power. Steel coils are also used in inductors, another type of electrical device. Inductors consist of a coil of wire wound around a core material, often made of steel. Steel coils in inductors help increase the inductance, which measures the device's ability to store energy in a magnetic field. By storing energy in this manner, inductors can regulate currents, filter out noise, and provide stability to electrical circuits. All in all, steel coils are indispensable in the production of electrical devices. They provide stability, support, and enhance the necessary magnetic properties for efficient functioning. Without steel coils, the performance and reliability of electrical devices like transformers, motors, generators, and inductors would be greatly compromised.

Q: How are steel coils processed before they are used in manufacturing?: Steel coils are processed before they are used in manufacturing through a series of steps including cleaning, pickling, cold rolling, annealing, and coating. These processes remove impurities, improve surface quality, reduce thickness, enhance mechanical properties, and provide corrosion resistance to ensure that the steel coils meet the required specifications for various manufacturing applications.

Q: How are steel coils handled during transportation to prevent damage?: Steel coils are typically handled with extreme care during transportation to prevent damage. They are secured tightly using steel strapping or bands to prevent any movement or shifting during transit. Additionally, protective packaging materials, such as wooden or steel crates, are often used to provide extra cushioning and stability. Specialized equipment, such as forklifts or cranes, are used to lift and load the coils onto trucks or containers, ensuring safe and secure transportation.

Q: I remember my dad saying something about steel toed boots but I forgot =#92; I went and checked out all the stores and got a pair with good ankle support but they also have steel toes. Would this interfere with the shifter or anything? I figure if anything my dirt bike shoes have the steel toes too. Any opinion?: Very good to have steel toed boots while riding

Q: bullets are normally made out of lead...are there bullets that are completely steel?? (not plated): I personally know of no steel bullets. In order to be soft enough to engage the rifling in the barrel, it would have to have a jacket at least the thickness of the groove depth. Separate loading(those which a projectile is loaded followed with various sized powder charges) howitzer projectiles are cast steel with copper driving bands set in grooves to engage the rifling.

Q: How is the quality of steel coils determined?: The quality of steel coils is determined through various tests and inspections, including visual examination, dimensional inspection, mechanical properties testing, and chemical analysis. These assessments help identify defects, such as surface imperfections, cracks, or variations in thickness and width, as well as ensure the desired mechanical properties and chemical composition of the steel.
