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: Recently I bought Bleach's Grimmjow's replica sword from swordsswords and I was wondering how strong is 440 steel when used for a 21 inch blade? Can it cut effectively? Is it dangerous?: You were seriously ripped off. I own a 440 stainless sword that I paid $29 for on eBay. It ain't a half bad sword actually, and like you said, I have never failed to cut straw mats with it. The 440 stainless is about as good as you can get without paying for a folded steel katana. However, I also own a Bugei company folded steel katana and the difference is night and day. The balance is better, the edge is incredible (you could literally shave with it) and there's just something....ELSE. There's a different FEEL. It's like the difference between using a tool and a weapon. As far as the shingami, again, you were ripped off. You can buy a traditional shingami from eBay and actually get it from a reputable company and not take your chances with the stuff you find at a mall. Even then, you will only pay maybe $50-$75 for a good set including shipping. Generally speaking, nothing you get from a mall or COULD get from a mall will be as good as something from a reputable company like Bugei. However, like in the case of your katana, some things might be good ENOUGH for you. However, you do need to look around and do some price checking before you drop that much money for anything. Hope this helps... Sensei Cox

Q: How are steel coils used in the automotive stamping industry?: Steel coils are used in the automotive stamping industry to provide a continuous supply of flat steel sheets that are then fed into stamping machines. These coils are unrolled, straightened, and then fed through the stamping presses to create various automotive parts, such as body panels, chassis components, and other structural parts. The use of steel coils ensures efficiency, precision, and a consistent quality in the production of automotive parts.

Q: I have a steel support beam can you remove one of the poles . the steel beam set on sender blocks on both side of the foundation. I have three steel beams support beam across the basement,I just want to remove one pole, can that be done.: i would say no. it sounds like it is a baring wall. so if you take out one pole it is going to weaken the entire house.

Q: I want to buy a machete made of 1055 carbon steel, and want to know if this steel is durable for repeated use, or even combat use.: 1055 Carbon Steel

Q: Okay, I have looked all ovcer the net and it says diamonds are stronger, but why? I mean, why is diamonds used for the top equiptment rather than steel?: Diamonds okorder

Q: What is the maximum length of a steel coil?: The maximum length of a steel coil can vary depending on various factors such as the manufacturing process, transportation limitations, and storage capabilities. However, it is common for steel coils to have a maximum length of around 30 meters (100 feet) or even longer in some cases.

Q: How do steel coils perform in high-pressure applications?: Steel coils perform well in high-pressure applications due to their inherent strength and durability. The high tensile strength of steel allows it to withstand the intense pressure without deformation or failure. Additionally, steel coils can be manufactured to precise specifications, ensuring they can handle the specific pressure requirements of the application. Overall, steel coils are a reliable and efficient choice for high-pressure applications.

Q: What is the lifespan of a steel coil?: The lifespan of a steel coil can vary depending on various factors such as the quality of the steel, its usage and maintenance. However, on average, a well-maintained steel coil can last anywhere from 10 to 30 years.

Q: What are the disadvantages of using steel coils?: One disadvantage of using steel coils is their weight and size, which can make transportation and handling challenging. Additionally, steel coils are susceptible to corrosion, requiring regular maintenance and protective measures to prevent rusting. The production of steel coils also contributes to environmental pollution due to the energy-intensive manufacturing process. Lastly, the upfront cost of steel coils can be relatively high compared to other materials, which may not be suitable for budget-constrained projects.

Q: What are the typical lead times for steel coil orders?: The typical lead times for steel coil orders can vary depending on various factors such as the quantity and specifications of the coils, current market conditions, and the supplier's production capacity. However, lead times commonly range from a few weeks to a couple of months. It is always best to confirm with the specific supplier for accurate and up-to-date lead time information.
