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.

FAQ

1. Do you have QC team?
Yeah, sure, our QC team is very important, they will keep the quality control for our products.for quality inspection every day.

Q:a picture of the atomic structure of carbon steel: This is actually a quite complex question... The atomic arrangement in steels can be controlled over a pretty wide range of different structures. This is really the fundamental reason why steel is such a commonly used material. The different atomic structures produce different physical properties so metallurgists have developed many different processes to control the atomic structure to get the properties they want. One simple answer is that Fe is BCC, body centered cubic at room temperature at equilibrium conditions. When you heat Fe up, it transforms to FCC, face centered cubic. If you continue heating Fe, it goes back to BCC, then it melts. The addition of C makes these structures (and the transformation temperatures) different. Deviating from equilibrium conditions by, for example, cooling very quickly (quenching) creates different atomic structures (one of the most important is known as martensite). Depending on how much C is in the steel, you can also have two different atomic structures (two different phases) present in equilibirum, for example, pearlite which is a mix of alpha Fe (BCC) and iron carbide Fe3C (orthorombic crystal structure). So... you need to think a little more about exactly what you want a picture of. I hope this helps

Q:Ok, so I'm obsessed with learning how to play the guitar (I preffer acoustic)... I'm a teenage girl that wants to play rock/pop/folk music... I want to learn first how to strum... then eventually how to pick...so what type of string is better? nylon or steel?: This Site Might Help You. RE: Steel or Nylon guitar? Ok, so I'm obsessed with learning how to play the guitar (I preffer acoustic)... I'm a teenage girl that wants to play rock/pop/folk music... I want to learn first how to strum... then eventually how to pick... so what type of string is better? nylon or steel?

Q:Explain why a steel nail sinks but a steel ship floats.: The vertical buoyancy force is equal to the weight of displaced fluid. Therefore, for a steel nail to sink, the weight of fluid it displaces is less than the weight of the nail itself. While the steel ship displaces a very large amount of fluid, thus generating a sufficiently high buoyancy force to keep the ship afloat.

Q:How are steel coils used in the manufacturing of railway tracks?: Steel coils are used in the manufacturing of railway tracks as they provide the necessary strength and durability. These coils are processed and cut into specific lengths to form the rails, which are then laid on a bed of ballast. The steel coils are also used to create other components of the railway track, such as sleepers and fasteners, ensuring a secure and stable infrastructure for trains to travel on.

Q:Im going to buy T-304 Stainless Steel exhaust tips for my truck. Is T-304 Stainless Steel good metal?: Surprisingly any stainless steel is considered soft or tough metal. A hardness tester will bare this out. It resists work hardening which means you can bend it many more times than cold rolled or hot rolled steel before it will break. Your choice is a good one for your intended purpose.

Q:Two different shaving razors I'm looking to buy have different specs. in terms of the metals used for the blade; one being 1045 surgical stainless steel, the other 440 stainless (not sure if its A B or C, but probably 440A or 440B because it's not specified). So which one is better for the intended use as a shaving razor?: yes a stainless steel 440 knife is really good my uncle bought one back in 1979 and has been having it without any problems the blade is still razor sharp even at 35 years old

Q:I just purchased this Benchmade knife with m390 steel blade and it cost me a fortune but I wanted to know if this new steel is a tool steel. what classifies a tool steel. M390 = 1.9 carbon, 20. chromium, .30 manganese, 1. molybdenum, .60silicon, .60 tugsten, 4. vanadium at 60-62 HRC: Not all tool steels work well in knife blades, but some of them are very popular. D2, M2, M4 and many others.

Q:How do steel coils contribute to the manufacturing of steel furniture?: Steel coils are an essential component in the manufacturing of steel furniture as they serve as the raw material for creating various steel components. These coils are used to form and shape the different parts of the furniture, such as frames, legs, and supports. The coils are unwound and cut into the required lengths, then passed through various machines like presses and rollers to bend, shape, and join them together. This process allows for the customization and fabrication of the steel furniture, ensuring strength, durability, and the ability to withstand heavy loads. Overall, steel coils play a crucial role in shaping and forming the structural elements of steel furniture, providing the necessary strength and stability to the finished product.

Q:I'm writing a book, and there is a part where there is a death arena with a white-hot river of steel. How hot would that be?: For the best answers, search on this site okorder White Hot XG is the best from those two.

Q:What are the different types of steel coil surface treatments for corrosion resistance?: To enhance corrosion resistance, different methods are utilized for treating the surface of steel coils. These treatments create a protective layer that prolongs the lifespan of the steel and prevents corrosion. Some commonly used treatments for corrosion resistance include: 1. Galvanizing: Widely recognized as an effective method, galvanizing involves applying a layer of zinc to the steel coil's surface. The zinc acts as a sacrificial anode, corroding before the steel, thus safeguarding it against rust and corrosion. 2. Chromate conversion coating: This treatment entails applying a chromate-based solution to the steel coil's surface. The chromate forms a thin film that serves as a protective barrier against corrosion. Moreover, it improves the adherence of paint or other coatings that may be applied subsequently. 3. Phosphating: Phosphating is a process where a phosphate coating is added to the steel coil. This coating establishes excellent corrosion resistance by chemically bonding with the steel surface. It also enhances the adherence of subsequent coatings or paints. 4. Organic coatings: These coatings comprise paint or epoxy and are applied to the steel coil to create a barrier between the steel and its surroundings. They offer corrosion resistance and enhance aesthetic appeal. The selection of organic coating depends on the specific application and the desired level of corrosion protection. 5. Zinc-rich paint: Similar to galvanizing, zinc-rich paint contains a high concentration of zinc particles. When applied to the steel coil, these particles provide sacrificial protection, preventing corrosion. This coating is commonly employed in harsh environments or for steel coils exposed to frequent moisture or saltwater. It is important to consider various factors such as the application, environment, budget, and required level of corrosion resistance when choosing a surface treatment. Consulting with a steel coil manufacturer or corrosion specialist is advisable to determine the most suitable treatment for a specific situation.
