- Q: What are the common applications of pre-painted steel coils?
- Pre-painted steel coils are commonly used in various industries for applications such as roofing, siding, wall cladding, and appliances. They provide a durable and aesthetically pleasing finish, making them ideal for both residential and commercial construction projects. Additionally, pre-painted steel coils are also utilized in automotive manufacturing, electrical enclosures, and industrial equipment due to their corrosion resistance and versatility.
- Q: I bought a damascus steel knife. It will be used for display. Nothing like hunting/skinning. If It is just sitting around, will it rust? (assuming that it isn't getting wet) Thanks for the help.
- Damascus Steel Rust
- Q: I am doing a project on how revolvers work and what materials they use and would like to know what specific grade of stainless steel they use for the manufacturing of the frame and cylinder?
- *Rifle barrels are usually made from steel alloys called ordinance steel, nickel steel, chrome-molybdenum steel, or stainless steel, depending upon the requirements of the cartridge for which they are chambered. The higher the pressure and velocity of a cartridge (pressure and velocity usually go up together), the faster it will wear out a barrel. To give a satisfactory service life, barrels for high velocity cartridges must me made from tougher and harder steel than barrels for lower pressure cartridges. *The 400 (416) series SS commonly known as ordnance grade , is what barrels are made from . *If you want your barrel to be made from super alloy then it is 718 Inconel ,but a costly affair.
- Q: Iron melts faster when there will be low carbon in Iron.During steel making the molten Iron gets purified and alloying being done through the process. How the carbon is being controlled at Iron melting stage and what it is called?
- Steel is usually made in a two-step process. As you may know, carbon, in the form of coke, is added to the iron ore during the initial smelting process. This is the first step. The conversion of iron ore into raw iron is accomplished with a blast furnace. Carbon dissolves with the iron during the smelting process. The amount of carbon in the iron is generally not controlled at this point as this would be too difficult, the excess carbon is removed in the next step. The result is pig iron which is crude iron that has a very high carbon content, and a large amount of impurities. Pig iron is almost as brittle as glass, and it is useless in this form. In most modern steelmaking operations, molten pig iron is tapped from the blast furnace three or four times per day- it is not allowed to cool. The liquid pig iron is carried in ladles directly to a Basic Oxygen Furnace which converts the pig iron into steel. The basic oxygen converter uses a stream of pure oxygen to burn off the excess carbon. Impurities are also burned off, particularly phosphorus, silicon, and sulfur (which damage the steel's properties.) These elements all have a much higher affinity for oxygen than iron does, so the iron itself remains unchanged. Once the carbon content and the impurities are reduced to the desired level. The oxygen is shut off, and the iron has now become steel. At this point other alloying elements may be added, such as chromium, manganese, or molybdenum. These elements improve the steel's properties, but also add to it's price. If necessary, more carbon can be added as well if the carbon content has accidentally dropped too low. Finally, molten steel from the basic oxygen furnace is poured off. It can be cast into ingots, billets, or thin slabs.
- Q: Can steel coils be returned if they are damaged?
- Yes, steel coils can be returned if they are damaged. Most suppliers and manufacturers have return policies in place for damaged goods, including steel coils. It is important to contact the supplier or manufacturer promptly and provide documentation or evidence of the damage to initiate the return process.
- Q: Why is steel a stiff material?I'm doing a project on the use of steel in the construction of skyscrapers - and obviously, for the inner steel skeleton of a skyscraper the steel support beams and girders will have to be stiff so that they don't fall apart or the building doesn't shake due to wind or other natural forces.But in my research I've found that steel (mild steel to be more exact) is ductile and malleable, meaning it can be shaped fairly easily. However, how can steel ALSO be stiff - the definition of stiffness is the tendency to withstand bending and stretching - so my question is. How can this material be BOTH ductile/malleable, AND stiff? and why? :)Thank you in advance if anyone takes the time to answer this, would be appreciated - I'll give you 10 points straight away if the answers conclusive
- Steel is NOT stiff. In fact it is worldly accepted metals (steel is a metal) are not rigid in mechanical terms, and rigid means stiff. Steel easy to shape, but is strong and therefore hard to break. Thermosetting polymers (hard plastic) which is stiff, is in fact easy to break (weak) and also hard to reshape without changing its state (solid to liquid). Whoever told you steel is stiff is wrong and possible meant steel is strong, or you misheard/misunderstood.
- Q: What are the common coil diameters available for steel coils?
- Steel coils come in a range of common diameters depending on the industry and purpose. Generally, the most frequently used coil diameters for steel range from 24 inches to 72 inches. These diameters are commonly utilized in sectors like automotive, construction, and manufacturing. It should be noted that the required coil diameter might vary depending on factors such as the material's size and weight, the equipment used for coil handling, and the specific requirements of the end-use application.
- Q: Are steel coils used in shipbuilding?
- Yes, steel coils are commonly used in shipbuilding. They are used primarily for the construction of the ship's hull and other structural components due to their strength, durability, and ability to withstand harsh marine environments.
- Q: How are steel coils inspected for chemical composition?
- The chemical composition of steel coils is examined using spectroscopy, a process that involves the utilization of a spectrometer. This instrument analyzes the light emitted or absorbed by a sample to determine its chemical makeup. Normally, a small portion of the coil is taken and prepared for analysis in the case of steel coils. This portion is then placed in the spectrometer, where a beam of light is emitted onto it. The light interacts with the atoms and molecules in the sample, causing specific wavelengths of light to be emitted or absorbed. The spectrometer measures the intensity of the emitted or absorbed light at different wavelengths and generates a spectrum, which is essentially a distinct fingerprint for the sample. This spectrum is then compared to a database of known spectra for various elements and compounds to ascertain the chemical composition of the steel. Through spectroscopic analysis, the presence and concentration of different elements like carbon, manganese, phosphorus, sulfur, and other trace elements in the steel can be identified. These elements have a significant impact on the steel's properties, strength, and suitability for different applications. Ensuring that the steel complies with the required specifications and standards, inspection for chemical composition is crucial in the steel industry. Any deviation from the desired chemical composition can potentially compromise the steel's performance and result in structural failures or other defects. In conclusion, spectroscopy offers a highly precise and dependable method for examining the chemical composition of steel coils. This aids in maintaining the quality and integrity of the steel products.
- Q: Explain your answers please. I was watching mythbusters and they bought a steel coffin over a wooden one because they thought it would hold more dirt. Now how come bridges that have been made of wood lasted way longer than steel bridges? Or rollercoasts for example.
- steel bridges that have been made of wood lasted way longer than steel bridges NOT true. Why do you think bridges are made from steel or concrete, and not wood? wood rots and splinters and doesn't last more than 10 years when exposed to the weather. .
