Description of Z47 BMP Prepainted Rolled Steel Coil for Construction
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.
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.

- Q: How are steel coils processed at the steel service centers?
- Steel coils are processed at steel service centers through a series of steps to transform them into finished products that meet the specific requirements of customers. The process typically begins with the arrival of the steel coils at the service center. These coils are typically large and heavy, and may have been produced by a steel mill or imported from overseas. Once the steel coils are received, they are typically inspected for quality and any defects. This ensures that only high-quality coils are used in the production process. The coils are then stored in a warehouse until they are ready to be processed. Next, the steel coils are uncoiled. This involves unwinding the coil to create a flat sheet of steel. This can be done manually or using automated machines depending on the size and thickness of the coils. The uncoiled steel is then leveled to remove any residual stress and ensure a flat and consistent surface. After leveling, the steel sheets may undergo various processes depending on the desired end product. These processes can include cutting, shearing, slitting, and forming. Cutting and shearing involve cutting the steel sheets into specific sizes or shapes. Slitting involves cutting the steel into narrow strips, while forming involves bending or shaping the steel into the desired form. Once the desired processing operations are complete, the steel sheets are often treated with surface finishes to enhance their appearance or protect them from corrosion. These finishes can include painting, coating, or galvanizing. Finally, the processed steel sheets are inspected for quality again to ensure they meet the required specifications. They are then packaged and ready for shipment to customers, who may use them in various industries such as construction, automotive, or manufacturing. Overall, the processing of steel coils at steel service centers involves a combination of inspection, uncoiling, leveling, cutting/shearing/slitting/forming, surface finishing, quality control, and packaging. This process allows for the transformation of steel coils into finished products that are tailored to meet the specific needs and requirements of customers.
- Q: What are steel coils used for?
- Steel coils are used for a variety of applications, including manufacturing automobiles, construction materials, appliances, and machinery. They are also used in the production of pipes, electrical appliances, and packaging materials.
- Q: What are the different types of steel coil leveling methods?
- There are primarily two types of steel coil leveling methods: roller leveling and stretcher leveling. Roller leveling involves passing the coil through a series of rollers to remove any unevenness, resulting in a flat and level surface. Stretcher leveling, on the other hand, stretches the steel coil to remove any internal stresses and achieve a flat and level surface. Both methods are commonly used in the steel industry to produce high-quality and dimensionally accurate steel coils.
- Q: Correct me if I am wrong, but steel is an alloy between iron and carbon. Does the carbon in the steel stops the iron from rusting or corroding? Also what is the difference between mild steel and stainless steel?
- Mild steel is an alloy. It is the most common form of steel. Mild steel (a so-called carbon steel) is a general term for a range of low carbon (a maximum of about 0.3%) steels that have good strength and can be bent, worked or can be welded into an endless variety of shapes for uses from vehicles (like cars and ships) to building materials. The carbon does not stop the material rusting or corroding. In addition to iron, carbon, and chromium, modern stainless steel may also contain other elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, niobium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minimum of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel. The chromium in the steel combines with oxygen in the atmosphere to form a thin, invisible layer of chrome-containing oxide, called the passive film. The sizes of chromium atoms and their oxides are similar, so they pack neatly together on the surface of the metal, forming a stable layer only a few atoms thick. If the metal is cut or scratched and the passive film is disrupted, more oxide will quickly form and recover the exposed surface, protecting it from oxidative corrosion.
- Q: If you were selecting a tool steel for an extreme impact load application, which one would you pick? why?thanks
- It all depends what the application actually is. For hammers I would select a hammer grade B1 steel. For impact loading where an edge is needed I would be going for O1 or similar (oil quenching steels tend to be a little tougher than air hardening). For mining tools a very high manganese steel (Hadfields steel) - this is not a true tool steel. The best place to start is by looking at the ranking of the properties which you want - hardness v toughness v strength - and then use this to put the steels in rank order. Price and availablity then sort the problem out for you (in the real world).
- Q: How are defects in steel coils detected and resolved?
- Defects in steel coils are detected through various methods such as visual inspection, ultrasonic testing, magnetic particle inspection, and eddy current testing. Once a defect is identified, it is resolved through processes like grinding, welding, or cutting out the affected area. In some cases, the entire coil may need to be rejected or sent for further processing to eliminate the defect.
- Q: case hardening steel is adviced or thru hardening steel is most suitable?
- I don't know your application, but here is some advice. Case hard provides a hard shell around soft steel, depending on the bake, the case is usually .002-.008 thick. (thousands of an inch) Heat treated steel or tool steel is hard all the way thru. Case hardening, provides toughness with flexibility, however, once it's compromised, the part is scrap. Hardend tool steel is extreemly hard throughout and the harder it is, the more brittle it becomes. The application of the part will help you to determine the material needed. For instance; Plastic injection molds are very hard so the hot plastic wont erode them over years of use. Punch Press dies aren't as hard but are tougher to withstand the shock. Machine bolts are case hardened so they can last, but soft enough to allow some stretching during tightening. Either way, the time in mfg will be about the same. Most tool steels today cut like cheese, but take time to be heat treated. Tool steel will cost a bit more than low carbon steel. Low carbon steel is as machinable, and cheaper, but, again, the baking period is as long or longer than tool steel. There are a lot of materials on the market today that maintain the durability of heatreated steel without having to go thru that process. 4140, ( or chrome/moly) comes to mind. There are also some 400 series stainless that work as well, and others. You need to determine strength, flexibility, ease of mfg, cost and repairability when considering which steel to use.

- Q: i like stainless steel guns, especially the SW 686 .357, i plan on getting one but my question is would polishing the stainless steel make the gun more prone to corrosion over leaving it as it is? and will the polished surface appear uneven after use and sitting? obviously all metal takes some sort of upkeep but is polished more high maintenance than non-polished?
