DC03 COLD ROLLED STEEL COIL
Cold Rolled Steel is steel thathas been worked below its recrystallization temperature by passing it between apair of rollers. Recrystallization temperature is the temperature at whichgrains in the lattice structure of the metal have been rearranged, leaving it freeof strain and deformations. Cold Rolled Steel is pre-treated before being coldrolled with a process known as pickling, which uses strong acids to removescale and other impurities. The Cold Rolled Steel is then passed throughrollers to reduce its thickness. Most cold rolling takes place in multiplepasses and as the size of the Cold Rolled Steel is further reduced, itsstrength and hardness both increase, but its ductility decreases. After coldrolling, heating the metal up in a process known as annealing can restore someof its ductility. The final Cold Rolled Steel may be manufactured in the formof sheets, strips, bars, or other forms.
Application
It’s widely used in outdoor andinterior decoration, furnishing manufacturing, home appliance, automobile etc.

- Q: What are the different types of steel coil packaging techniques?
- There are several different types of steel coil packaging techniques that are commonly used in the industry. These packaging techniques are designed to protect the steel coils during storage, transportation, and handling, ensuring that they arrive at their destination in optimal condition. One type of steel coil packaging technique is known as "eye-to-the-sky" packaging. In this method, the steel coils are stacked vertically with the eye of the coil facing upwards. They are then secured using steel strapping or banding. This technique is often used for smaller coils and provides good protection against damage caused by handling and transportation. Another common packaging technique is known as "eye-to-the-wall" packaging. In this method, the steel coils are stacked horizontally with the eye of the coil facing the wall. They are then secured using steel strapping or banding. This technique is often used for larger coils and provides better stability during transportation. A third packaging technique is known as "shrink-wrapping." In this method, the steel coils are wrapped tightly in a plastic shrink-wrap material. This provides protection against moisture, dust, and other contaminants. Shrink-wrapping is often used when the steel coils need to be stored or transported outdoors or in harsh environments. Additionally, some steel coil packaging techniques involve the use of wooden pallets or skids. The coils are placed on these pallets or skids, which provide a stable base and allow for easy handling with forklifts or other equipment. The coils can then be secured to the pallets or skids using steel strapping or banding. Overall, the choice of steel coil packaging technique depends on factors such as coil size, transportation requirements, and environmental conditions. By selecting the appropriate packaging technique, steel coils can be effectively protected and delivered to their destination without damage or deterioration.
- Q: Iron too heavy for Ulysses but if there was any iron used id imagine it was steel. Can steel go deeper into sun than iron? Compare two bolts.. 1steel 1iron..is there a difference to what the steel can do?
- Dont understand are you going to put them in sun ? Sun made from gas wich is on fire. Its impossible to get to the sun and not to get burn. Steel is really more solid and strong than iron so its more hard to break it or to bend. But in camparing of fusion temperature - iron is a bit more better, though it would not make a big difference .From metals - tungsten has the highest fusion temperature - near to 3400 C . Iron is near to 1530 C, steel is near to 1300 -1500 C. So according to this tungsten can go most close to sun. Right near the sun temperature is millions of degrees so anything will fuse and burn there.
- Q: I am thinking about getting a cold steel tilite or a kershaw leek or possibly a buck sirus. If you have had any experience with these knives please give it to me. thanks
- Cold Steel while not made in the U.S. are still good knifes. I EDC a 2 Mini Tanto as my third knife for over 16 years. Recently the scales fell off and were lost, they are no longer available. My #2 EDC for the last 11 years has been a Kershaw Chive and it is still on my belt behind my Blackberry. I move between 2 EDC primary knives a 1996 Benchmade/Emerson CQC-7 and a Emerson Model I folder. I have gotten great service from all of them, and I rate them as follows: 1) Emerson 2) Cold Steel or Benchmade (Blue or Black Box product) 3) Benchmade (Red Box - made outside of US) or Kershaw All of the 2nd and 3rd tetieruys have non US products, not neccessarily bad. I have had good results all of them. Value for the dollar = Benchmade Blue Box. Decent value for entry price Kershaw is good as a first knife. Hope this helps.
- Q: How are steel coils affected by global trade policies?
- Steel coils are significantly affected by global trade policies as they are subject to various tariffs, quotas, and trade restrictions imposed by different countries. These policies can impact the cost, availability, and competitiveness of steel coils in the international market. Changes in trade policies can lead to fluctuations in demand and supply, impacting the prices and trade volumes of steel coils.
- Q: What is steel made of? What are the elements other than iron?

- Q: What are the common challenges faced in steel coil production?
- Some common challenges faced in steel coil production include ensuring consistent quality and thickness of the coil, maintaining efficient production rates, managing inventory and storage of coils, addressing issues related to coil surface defects and handling, and adhering to strict safety regulations. Additionally, fluctuations in raw material prices and market demand pose further challenges for steel coil producers.
- Q: My 8-year-old and 9-year-old boys have approached me with an interesting question. Does fire burn steel? One says yes, the other says no. Help me to settle yet another debate :)
- Fire doesn't burn steel, fire is the catalyst for steel to react with oxygen and burn though technically it's oxidizing. An intense flame like that found in an Oxy-Acetylene torch will bring the steel to melting point, then the operator would toggle a lever on the torch blasting pure oxygen into the steel causing it to oxidize and fall away from the workpiece. The afore mentioned steel wool exercise illustrates the principle on metal so thin that the heat provided by a candle allows for oxidization with the oxygen present in the atmosphere.
- Q: How long does the coating on steel coils last?
- The longevity of the coating on steel coils can vary depending on a variety of factors including the type of coating, environmental conditions, and usage. However, with proper maintenance and protection, a well-applied coating can typically last anywhere from 10 to 30 years.
- Q: What are the factors that affect the quality of steel coils?
- The quality of steel coils can be influenced by various factors. To begin with, the composition of the steel itself plays a vital role in determining its quality. Impurities like sulfur or phosphorus can have a negative impact on the strength, durability, and overall performance of the steel. Additionally, the quality of the steel is affected by its carbon content, alloying elements, and heat treatment. Furthermore, the quality of the steel coils is greatly affected by the manufacturing process and techniques utilized during production. Factors such as the cleanliness of the production environment, the precision of the rolling and cooling processes, and the control of temperature and pressure throughout manufacturing all contribute to the final quality of the coils. Additionally, the surface quality of the steel coils is a crucial factor. Any defects or imperfections on the surface, such as scratches, dents, or corrosion, can compromise the integrity and functionality of the coils. It is essential to handle, store, and transport the coils properly to maintain their surface quality. Moreover, the mechanical properties of the steel coils, including tensile strength, yield strength, and elongation, are essential indicators of their quality. These properties depend on various factors, such as the type of steel, its thickness, and the processing conditions. Lastly, external factors such as environmental conditions, like humidity and temperature, can affect the quality of steel coils. Exposure to moisture or extreme temperatures can lead to corrosion or other forms of degradation, impacting the overall quality and lifespan of the coils. In conclusion, the quality of steel coils is influenced by several factors, encompassing the composition of the steel, the manufacturing process, surface quality, mechanical properties, and external environmental conditions. It is crucial to carefully control and monitor these factors to produce high-quality steel coils that meet the desired specifications and standards.
- Q: Does steel have a valence number and if so, what is it?
- Steel is a mixture, so it doesn't have any valence number. On the other hand, all of the components of the steel mixture are in their elemental forms, so all the various valences are zero.
