Q:which one(glass or steel)has more power and velocity? im planning on using my slingshot for hunting.: definitely steel. i used to hit bullseyes with a good slingshot, and you need heavy, perfectly spherical small steel shot. smaller than a marble, bigger than a bb.

Q:I know there is soft steel and sturdier steel they use in products. The sturdier often used for equipment that requires more durability when in operation.: harder steel has a higher carbon and chromium content

Q:How are steel coils used in the manufacturing of automotive parts?: Steel coils are used in the manufacturing of automotive parts as they are shaped and formed into various components such as body panels, chassis frames, and suspension parts. The coils are processed through a series of steps including cutting, bending, and stamping, to create the desired shape and size for each specific part. These steel components provide strength, durability, and structural integrity to the automobiles, ensuring their safety and performance on the road.

Q:ok I got a dpms ar 15 and all i have put though it is good brass 223 ammo but is it ok to shoot the old crappy steel cased wolf ammo out of it will it hurt its function or will it hurt it cosmetically?: The primary complaint about wolf steel cased stuff besides it being dirty is that is wears out the chamber and extractor faster than brass. That is not true. It would be true if the cases were actually steel instead of a mixture that has a hardness that is close to brass. Now to prove how pervasive this myth is I expect a minimum of 4 thumbs down for this statement alone. In any case the only issue is that is you do use steel cased ammo the chamber has to be better cleaned. The residue left behind from the coating on the steel casings will build up. If you keep firing the cheap steel cased stuff this tend to be less of an issue but when you use brass cased ammo without cleaning the chamber out or in the same session once it heats up the stuff will actually grip the brass tightly causing case head tears. And your only option is to wait for the gun to cool down yank it out by hand because at that point the casing is in essence glued into the chamber.

Q:How do steel coils contribute to seismic resistance in structures?: Steel coils contribute to seismic resistance in structures by providing strength, flexibility, and energy dissipation. When steel coils are incorporated into the structure's design, they act as seismic dampers, absorbing and dissipating the energy generated during an earthquake. The coils help to distribute and reduce the seismic forces, minimizing structural damage and enhancing the overall stability and resilience of the building. Additionally, the flexibility of steel coils allows them to withstand forces without breaking, ensuring the structure's integrity and safety during seismic events.

Q:Can steel coils be coated with anti-fingerprint materials?: Yes, steel coils can be coated with anti-fingerprint materials. These materials are designed to reduce the visibility of fingerprints and smudges on the surface of the steel, providing a cleaner and more aesthetically pleasing appearance.

Q:How are steel coils inspected for surface finish using profilometry?: Steel coils are inspected for surface finish using profilometry by measuring the surface topography using a profilometer. The profilometer scans the surface of the steel coil and records the deviations from the ideal surface. This data is then used to determine the roughness, waviness, and other surface parameters of the steel coil, providing a quantitative assessment of its surface finish quality.

Q:What are chemical properties of high speed steel? Physical properties?What is high speed steel used for? One interesting fact about high speed steel?: wikipedia: High speed steel (often abbreviated HSS, sometimes HS) is a material usually used in the manufacture of machine tool bits and other cutters. It is often used in power saw blades and drill bits. It is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high speed steel. At room temperature, in their generally recommended heat treatment, HSS grades generally display high hardness (above HRC60) and a high abrasion resistance (generally linked to tungsten content often used in HSS) compared to common carbon and tool steels. see reference for more info .

Q:what happened to all the steel beams from the WTC buildings? did anyone do any forensic analysisof any of the steel?: some of the steel was recycled into a warship. I am not sure at what you are trying to get at with the forensic analysis of the steel. There is no conspiracy involving the towers outside of planes crashing into them despite what a lunatic fringe want you to think.

Q:Having a greater amount than 2% carbon in steel causes steel to suddenly become brittle. Why is this?: Carbon fiber has better tensile capability then steel meaning its better while pulled aside. Plus you could mould the fiber to make autos-or homes-out of carbon fiber.
