Product Description

Brief Introduction
The Cold Rolled Steel is steel that has been worked below its recrystallization temperature by passing it between a pair of rollers. Recrystallization temperature is the temperature at which grains in the lattice structure of the metal have been rearranged, leaving it free of strain and deformations. The Cold Rolled Steel is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. The Cold Rolled Steel is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the Cold Rolled Steel is further reduced, its strength and hardness both increase, but its ductility decreases. After cold rolling, heating the metal up in a process known as annealing can restore some of its ductility. The final Cold Rolled Steel may be manufactured in the form of sheets, strips, bars, or other forms.

Q: i have a question on a test and the questions before it are about blast furnace, wrought iron and cast iron...question 16 is..What is Steel?i dont really get what im being asked.. there could be many answers, what answer are they looking for?: as steel is an alloy i thinkl they are looking for what elements it is made up of

Q: I bought a steel pendant on eBay, but it turned out to be too shiny.I've read on a couple forums that if I leave it soaked in urine for 2 days, it will get duller.Now, if it really does get duller, will the pendant get rusty afterwards?So is the shiny surface the only thing that prevents it from rusting?Any simple, non-urine ideas on how to make it duller are welcome too.Thanks!: Stainless steel will rust under proper conditions. I live on a boat on salt water, trust me. If the urine works it won't be prone to rusting any more than before. It's not the shine that inhibits rusting with stainless steel, it the % of carbon in the steel, compared to regular steel. IF the urine works it's because it is acidic (a mild acid). Wash it with a small brush and some baking soda to neutralize the acid when your done. A much stronger acid would be swimming pool acid. (Muriatic acid) but be careful you might test a spot with a Q tip on the back. If you try Muriatic acid it would take seconds.Then wash in baking soda water to remove all acid.. SS

Q: How are steel coils cut into smaller sizes?: Steel coils can be cut into smaller sizes using various methods, depending on the desired dimensions and quantities. One common method is called slitting, which involves passing the coil through a set of circular blades. These blades make multiple cuts simultaneously, creating narrower strips of steel. Slitting is often used to produce narrow coils or strips for specific applications such as automotive parts or electrical components. Another method is called shearing, which involves using a straight blade to cut the coil into smaller lengths. This method is typically used when precise dimensions are required, such as for manufacturing flat sheets or plates. Shearing can be done manually or using automated machinery. Additionally, some steel coils can be cut using laser or plasma cutting techniques. These methods allow for more flexibility in terms of shape and size, as they can create intricate cuts or contours. Laser or plasma cutting is commonly used when specific shapes or profiles are needed for applications like construction or fabrication. Overall, the process of cutting steel coils into smaller sizes involves various techniques such as slitting, shearing, laser cutting, or plasma cutting. The choice of method depends on factors such as the desired dimensions, quantities, and specific requirements of the end product.

Q: How are steel coils used in the manufacturing of braking systems?: Steel coils are used in the manufacturing of braking systems as they are shaped and formed into various components such as brake discs, brake pads, and brake calipers. These coils are made of high-quality steel that provides strength and durability, ensuring efficient and reliable braking performance for vehicles.

Q: I'm pretty sure that this topic has been beaten to death by now. But, I still can't get a definite answer. With stainless steel, you get better corrosion resistance, and you will hold and edge longer. With carbon steel, you will hold a sharper edge, and you could forge a knife blade longer than 2 ft without breakage. I'm personally a fan of stainless steel ( the 440 grade stuff ), just because it seems to hold up to use and abuse better in the long run. HOWEVER, I have NEVER had a factory made knife break on me. I don't think that they would try to sell you a knife that didn't do what it was meant to do, at least to a reasonable degree. (I work for a living, and can't afford a custom $600 knife.) What do you think? Is this a pointless topic? Will there ever be a winner?: I hate stainless steel! I hate shiny blades also! When I was a kid knifes were awesome! You could actually sharpen them! :) If we bought a new knife we would take an orange and slice it and leave the juice on the blade to purposefully darken it. If you had a shiny blade that looked like stainless you were not cool. :) I think most anyone who had an old knife from back in the 70's or before would agree that these new stainless knives are crap. I have not seen anything perform close to the old blades in stainless. Today I bought a case CV Sod Buster hoping it will perform like the old knives. What reading I have done the Chrome Vanadium is supposed to be like the old steel. I sure hope it is. Now to find some fruit to get rid of this annoying shiny blade! :)

Q: How are steel coils processed for specific applications?: Steel coils are processed for specific applications through a series of steps including cleaning, annealing, cold rolling, and coating. Cleaning removes any impurities from the surface of the steel, while annealing improves its ductility and strength. Cold rolling reduces the thickness and improves the surface finish of the steel, making it suitable for various applications. Finally, coating is applied to enhance corrosion resistance or to provide specific aesthetic properties.

Q: like, what can steel make?: buildings bridges automobiles elevators railroads and railroad equipment appliances and many many more. Steel is used almost everywhere. reference: Iron and steel are used widely in the construction of roads, railways, infrastructure, and buildings. Most large modern structures, such as stadiums and skyscrapers, bridges, and airports, are supported by a steel skeleton. Even those with a concrete structure will employ steel for reinforcing. In addition to widespread use in major appliances and cars (Despite growth in usage of aluminium, it is still the main material for car bodies.), steel is used in a variety of other construction-related applications, such as bolts, nails, and screws.[66] Other common applications include shipbuilding, pipeline transport, mining, offshore construction, pipeline transport, aerospace, white goods (e.g. washing machines), heavy equipment (e.g. bulldozers), office furniture, steel wool, tools, and armour in the form of personal vests or vehicle armour (better known as rolled homogeneous armour in this role). .

Q: How do steel coils contribute to energy savings in buildings?: Steel coils contribute to energy savings in buildings by being used in various applications that help improve insulation and reduce heat transfer. They are commonly used in HVAC systems, where they act as heat exchangers, transferring heat between air streams. Steel coils with high thermal conductivity ensure efficient heat transfer, allowing for effective cooling or heating of air without excessive energy consumption. Additionally, steel coils are utilized in the construction of insulated walls and roofs, forming an integral part of the building envelope. This helps minimize thermal bridging, preventing heat loss or gain through the building's structure. By improving insulation and reducing energy transfer, steel coils play a crucial role in enhancing the overall energy efficiency of buildings, leading to significant energy savings.

Q: My teacher says if they were that they would still be standing today. I'm not sure if he means the reinforced steel in the concrete beams, columns etc or if the whole beams and columns floor etc were were made of reinforced steel.: There is no way you could make a 110 floor building out of concrete.
