Product Description

Brief Introduction
The CRC Coil 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 CRC Coil is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. The CRC Coil is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the CRC Coil 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 CRC Coil may be manufactured in the form of sheets, strips, bars, or other forms.

FAQ

1.What's your MOQ?
25MT, it is for one container.
2.Do you have QC teams?
Yeah, sure, our QC team is very important, they will keep the quality control for our products.
3. What's your normal delivery time?
Our delivery time about 10-20days for standard sizes, if you have other requirements like hardness and width ,it is about 20-40days. But don't worry ,we also try our best for the delivery time ,because time longer and our cost is higher.
4.Are the products tested before shipping?
Yes, all of our PPGI and GI was qualified before shipping. We test every batch every day

Q: What is the (balanced) chemical equation for steel?: I hate to differ but I must. Steel is a mixture of iron and carbon but the carbon content ranges from a small fraction of a percent to no more than 2%. Stainless steel is an alloy of Iron and up to 15% or so of other metals but since there are several types and many varieties in each type it's hardly worth getting into. A good common hardenable high-carbon spring steel is AISI 1095. In this code the 95 refers to 0.95% carbon. When the carbon level goes up to 1.5% to 2% the steel is very brittle and black with the highest carbon steel being pretty much pig-iron.

Q: What are the different methods of painting steel coils?: There are several methods of painting steel coils, including coil coating, spray painting, and powder coating. Coil coating involves applying a liquid coating to the surface of the steel coil, which is then cured and dried. Spray painting involves using a spray gun to apply paint to the coil, typically in multiple layers. Powder coating involves electrostatically applying a dry powder to the coil, which is then cured and fused onto the surface. Each method has its advantages and is chosen based on factors such as durability, cost, and desired finish.

Q: Does anyone know how to make a steel helmet, or does anyone know where to direct me websites-wise? i've just started looking on the web for info, so when i get back here i might've already found some info, but more wouldn't hurt, especially if from people who are interested on the subject. i know nothing about metallurgy, nothing on the art of metal working etc... please help.: The okorder (Artist Blacksmiths) or on the sites of the two organizations that reproduce old costumes and tools - one is called The Society for Creative Anachronism, not sure of the other. Search terms to use might be hammering a helmet and forging medieval armor

Q: What are the dimensions of steel coils used in bridge construction?: The dimensions of steel coils used in bridge construction can vary depending on the specific requirements of the bridge project. However, generally speaking, the dimensions of steel coils used in bridge construction typically range from 0.5 inches to 1 inch in thickness and 36 inches to 72 inches in width. The length of the coils can vary as well, but is commonly around 20 to 40 feet. These dimensions allow for the fabrication of various structural components such as beams, columns, and plates that are essential for the construction of bridges. It is important to note that the dimensions may vary based on the specific design and engineering specifications of the bridge project, as well as the type and load capacity of the bridge being constructed.

Q: What are the common coil handling equipment used in the industry?: Some common coil handling equipment used in the industry are coil cradles, coil reels, coil straighteners, coil feeders, and coil transfer cars. These tools are essential for safe and efficient handling of coiled materials during various manufacturing processes.

Q: If a make a dish antenna of steel and of fiberglass, which would be more heavy and also which would be more expensive?: Steel will be heavier but easier to manufacture. There won't be a huge weight advantage because you can use steel mesh which works the same as solid, near enough, as an electromagnetic reflector. Steel can just be pressed, fiberglass has to be laid up of resin and mat and then allowed to cure. Fiberglass will also need to be coated in something conductive whereas you can just spray paint the steel, or even buy it pre-coated.

Q: Will a 8mm steel ball fired from a 150lbs crossbow kill small game and if so, from how many yards?: People usually compare regular fiber stringed crossbows with the string in steel ball crossbows. steel ball crossbows shoot with steel cables that can take the light weight of the ball . On top of that they are ALLWAYS have cams that reduce the tension when releasing the ball. I own a 160 lbs crossbow that shoots both bolts and 8mm balls and I love it, it can take a raccoon , a rabbit , even a turkey and it is very easy to reload since it keeps several balls in the magazine. About how accurate it is , as most shooting weapons it is a matter of practice. I have a pistol 6 mm balls and is really fun, I don't think you can kill much with that one but it is fun to shoot at around the house. I would give it a try , you might be pleasantly surprised.

Q: Can steel coils be stored in a humid environment?: Steel coils can be stored in a humid environment, but it is not ideal. Humidity can cause steel coils to rust and corrode, leading to potential damage or degradation of the steel. It is recommended to store steel coils in a dry and well-ventilated area to protect them from the negative effects of humidity.

Q: How are steel coils inspected for chemical composition?: Steel coils are inspected for chemical composition through a process called spectroscopic analysis. This involves taking a small sample from the coil and subjecting it to various tests, such as X-ray fluorescence or optical emission spectroscopy, to determine the precise elemental composition of the steel. This ensures that the steel meets the required specifications and quality standards.

Q: Can i make holes in iron and steel with somekind of drill bit. All i have is metal drill bits. Mabey like 68 of them but i dont know wich one to use and if they will penetrate.: If a drill bit will not do the job, you will have to go to something like EDM. But that is a lot of trouble, ask a machinist first.
