Q:if steel is heated from room temperature (20c) to (500c) what would be the change in density?coefficient for linear expansion of steel 12x10^-6 k density of steel 7800 kg: First you have to convert the coefficient of linear expansion to a coefficient of volumetric expansion. Multiply the coefficient of linear expansion by 3: Coefficient of expansion of steel,β:12E-6/°K x 3 = 36E-6/°K Difference in temperature: 480°K ΔV = VoβΔT ΔV = Vo x (0.000036) x 480 ΔV = 1m? x 0.017 ΔV = 0.017m? Originally, the steel was at 7800 kg/m? Now, the steel was at 7800 kg/ 1.017m?, or 7670 kg/m? Change in density = 7670 - 7800 = -130kg/m?

Q:so i just bought a stainless steel bracelet.......and recently found out that stainless steel isnt actually stainless..........will turpentine ruin it: real s/steel is nickel and chrome, however manufacturers of kitchenware, e.g s/teel cutlery use the cheaper version of nickel chrome and iron, that is why some s/steel products rust, so if you want to test any products carry asmall magnet and test the article

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:Can steel coils be used in marine environments?: Yes, steel coils can be used in marine environments. However, it is essential to ensure that the steel coils are properly protected against corrosion, as the saltwater and high humidity in marine environments can accelerate the process of rusting. Various coatings and treatments can be applied to steel coils to enhance their resistance to corrosion and make them suitable for use in marine applications.

Q:I'm going to see Man Of Steel this weekend, and the reviews that I've been hearing aren't that good. I've been hearing that it's this depressing, dark, dramatic film with no humor, loud noises, and action on top of action (which is kind of what I expected from this movie). With that said, I was quite positive that this was what the fans wanted, a more serious Super Man interpretation. I'm ultimately going to judge the movie when I see it, but for now, I have 3 short questions for you:1) What did you think of Man Of Steel?2) Superman Returns got somewhat better reviews than Man Of Steel. Does it seem logical?3) There is a huge fan battle between Man Of Steel and Christopher Reeve's version of Super Man. Which one do you favor?: saw it yesterday and it was great. all the complaints about it being gloomy...nonsense really. how would u feel if u found out ur life was a big question mark THEN u grow up only to get tossed in giant sh*t storm. many right now are excluding this is a story driven movie/character. u can't go in expecting anything with this movie especially ANY comparison to precious films. between Reeves and Cavill... I'm not gonna make that decision yet. this portrayal was one of a complete serious nature. u only get a couple glimpses of other emotions. the ending was a great lead off in which the sequel will showcase a lot more emotion within the character guaranteed. for now Reeves is still the best. until we all see Cavill display a full form of charm and charisma then the entire debate is really pointless

Q:How are steel coils priced?: Steel coils are priced based on various factors including the current market demand and supply, raw material costs, production and processing expenses, transportation and logistics costs, as well as any additional charges or fees imposed by the manufacturer or supplier.

Q:I was looking at my Great-Grandfather's immigration form from when he immigrated from Scotland and he listed his occupation as a steel dresser. What does a steel dresser do?: I'm not sure, but it could be like and engineer working in steel design or steel polisher. I checked Wikipedia and Yahoo but found nothing. It may be a description of something only in Scotland. Sorry

Q:Can steel coils be customized in terms of size and thickness?: Yes, steel coils can be customized in terms of size and thickness. Manufacturers have the capability to produce steel coils in various sizes and thicknesses to meet the specific requirements of different industries and applications.

Q:What are the common coil lengths available for steel coils?: The common coil lengths available for steel coils vary, but typically range from 5,000 to 15,000 feet.

Q:How do steel coils withstand extreme temperatures?: The unique composition and manufacturing process of steel coils enable them to endure extreme temperatures. Steel, the primary material in coils, consists of iron and carbon, forming an alloy with exceptional thermal properties. With a high melting point of up to 2,500 degrees Fahrenheit (1,370 degrees Celsius), steel remains structurally stable even in intense heat. Additionally, the annealing process is commonly applied to steel coils. This involves heating the steel to a specific temperature and gradually cooling it down. By relieving internal stresses, annealing enhances the steel's resistance to thermal expansion and contraction. It also reduces internal defects, thereby improving the overall strength and durability of the steel, enabling it to better withstand extreme temperatures. Furthermore, protective coatings are often applied to steel coils to provide additional resistance against temperature fluctuations. These coatings, such as galvanized or zinc coatings, act as a barrier between the steel and the external environment. They effectively prevent oxidation, corrosion, and other forms of degradation that can occur when exposed to extreme heat or cold. In conclusion, the ability of steel coils to withstand extreme temperatures can be attributed to the inherent properties of steel, the annealing process that relieves internal stresses, and the protective coatings that offer an extra layer of resistance. These factors work in harmony to ensure that steel coils maintain their structural stability and performance, even in the most challenging temperature conditions.
