- Q:Correct me if I am wrong, but steel is an alloy between iron and carbon. Does the carbon in the steel stops the iron from rusting or corroding? Also what is the difference between mild steel and stainless steel?
- Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
- Q:I need to know a name of any site which provides information on Steel structures??
- What information are you looking for specifically? information on steel structures could refer to lots of things. Try the American Institute of Steel Construction, or the American Society of Civil Engineers. Google to find them.
- Q:What are the common coil inspection techniques?
- Common coil inspection techniques include visual inspection, magnetic particle inspection, eddy current testing, ultrasonic testing, and radiographic testing.
- Q:I was just thinking, is their a way to make steel qualities inherent in concrete, therefore eliminating the need for re bar?
- There is an iron powder reinforced concrete flooring that improves abrasion resistance. However, you cannot get the tensile strength enhancement that is possible with rebar.
- Q:What is the process for uncoiling and recoiling steel coils?
- The process for uncoiling and recoiling steel coils involves several steps to ensure the safe and efficient handling of the coils. 1. Unloading: The steel coils are typically transported to the desired location using cranes or forklifts. They are carefully unloaded from the transportation vehicle and placed in a designated area. 2. Inspection: Before uncoiling, it is crucial to inspect the steel coils for any damage or defects. This step ensures that only quality coils are processed further. 3. Securing: Once inspected, the steel coils are secured to prevent any movement during the uncoiling process. This is done by using clamps or straps to hold the coils firmly in place. 4. Uncoiling: Uncoiling involves the gradual unwinding of the steel coil. This can be done manually or using specialized machinery such as uncoilers or decoilers. The coil is typically fed through a series of rollers that help guide the unwinding process. 5. Straightening: In some cases, the steel coil may need to be straightened before further processing. This can be done using straightening machines that apply pressure to remove any bends or twists in the steel. 6. Cutting: If required, the uncoiled steel coil may be cut into smaller sections or sheets. This can be done using shearing machines or other cutting tools. The dimensions and size of the cuts depend on the specific requirements of the project. 7. Recoiling: Once the desired processing steps are completed, the steel coil can be recoiled. This involves rewinding the steel into a new coil shape. Recoiling can be done manually or using recoilers, which wind the steel evenly and tightly to maintain its integrity. 8. Packaging and storage: After recoiling, the steel coils are typically packaged and stored for further transportation or use. They may be wrapped in protective materials such as plastic or metal sheets to prevent corrosion or damage. Overall, the process for uncoiling and recoiling steel coils requires careful handling, inspection, and the use of specialized machinery. By following these steps, steel coils can be efficiently processed and prepared for various applications in industries such as construction, automotive, and manufacturing.
- Q:How are steel coils processed for slitting or edge conditioning?
- Steel coils are processed for slitting or edge conditioning through a series of steps. First, the coils are unwound and flattened using a decoiler. Then, they are fed through a slitting machine, which cuts the wide coil into smaller strips of the desired width. These strips are then recoiled to create narrower coils. For edge conditioning, the coils are passed through an edge trimmer, which removes any rough or uneven edges. Finally, the coils are recoiled again and packaged for further use or distribution.
- Q:My musical saw has, despite my best efforts, got little patches of rust on it. How Do I go about removing the rust without spending too much on rust-removal products and without affecting the properties of the steel?
- I would suggest rust removal by electrolysis. Search youtube for that. It probably will not affect the metal but there are no guarantees. I would run a test on another metal. Also this process can be dangerous because hydrogen gas is a by-product - remember not to smoke or be cooking nearby! The Easy way is with BlackStar Rust Remover. It will turn the metal black and convert the rust to metal which can then be painted or left black.
- Q:What are the typical tolerances for steel coils?
- The typical tolerances for steel coils can vary depending on the specific requirements and standards of the industry. However, common tolerances for steel coils typically range between +/- 0.005 to 0.020 inches in terms of thickness, width, and length. These tolerances ensure that the steel coils meet the desired specifications and can be used effectively in various applications.
- Q:How do steel coils contribute to the manufacturing of HVAC systems?
- Steel coils are used in the manufacturing of HVAC systems primarily for their strength and durability. They form the core structure of various components such as heat exchangers, condenser coils, and evaporator coils. The steel coils provide stability and support, ensuring the longevity and efficiency of HVAC systems by withstanding high temperatures, pressure, and constant use.
- Q:A 100 kg solid steel ball with a radius of 5 m is being spun on ice with an angular velocity of 5 rev/s pointed into the ice (clockwise rotation when viewed from above).A student shoots a 10 kg marble at the steel ball. The marble hits the ball along its side as shown with an initial velocity of 5 m/s to the left. If, right after the collision, the final velocity of the marble is 2.5 m/s to the left, what is the angular velocity of the steel ball after the collision?
- You need to do conservation of angular momentum about the steel ball's axis. Angular momentum = I.ω The steel ball's initial ω = 5 rev/s = 5*2pi rad/s = 31.4 rad/s The steel ball's moment of inertia I = (2/5)*m*r^2 = 40*25 kg.m^2 = 1000 kg.m^2 The marble's initial ω = v / r where r is the perpendicular distance from the steel ball's axis You need to look at the diagram for this. The marble's I about the steel ball's axis is I = m*r^2 where r is the same as above. (marble is treated as a point mass). Then work out the total initial ang. momentum = final ang. momentum and solve for ω...
