Description of Z49 BMP Prepainted Rolled Steel Coil for Construction
Cold rolled steel 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. Cold rolled steel 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 cold rolled steel coil 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 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 cold rolled steel coil may be manufactured in the form of sheets, strips, bars, or other forms.

- Q: Does steel contain nickel?
- Yes. Different alloys contain differing amounts.
- Q: What are the factors affecting the strength of steel coils?
- There are several factors that can affect the strength of steel coils. 1. Steel Grade: The type and quality of the steel used in the coils plays a significant role in determining their strength. Different steel grades have varying levels of carbon content, alloying elements, and heat treatment processes, which can impact the overall strength and durability of the coils. 2. Manufacturing Process: The way in which the steel coils are manufactured can also affect their strength. Factors such as the temperature and duration of the heat treatment, the rolling and annealing processes, and the level of cold working can all influence the final strength of the coils. 3. Thickness and Width: The thickness and width of the steel coils can affect their strength. Thicker coils tend to be stronger and more resistant to deformation, while wider coils may exhibit variations in strength across their surface. 4. Surface Quality: The condition of the coil's surface, including any imperfections or defects, can influence its strength. Surface defects such as scratches, pits, or corrosion can act as stress concentration points, reducing the overall strength of the coil. 5. Storage and Handling: The way in which the coils are stored and handled can impact their strength. Factors such as exposure to moisture, extreme temperatures, or improper stacking and transportation can lead to deformation or damage, decreasing the strength of the coils. 6. Environmental Conditions: Environmental factors such as humidity, temperature, and exposure to corrosive agents can also affect the strength of steel coils. In harsh environments, the coils may experience accelerated corrosion, leading to a decrease in their strength over time. It is important to consider these factors when selecting and utilizing steel coils to ensure that they meet the required strength specifications for the intended application.
- Q: What is the average price of a steel coil?
- The average price of a steel coil can vary depending on factors such as the type of steel, size, and market conditions. It is best to consult with suppliers or industry reports for the most up-to-date and specific information on current average prices.
- Q: Could someone please explain what happens when steel is heat treated and why these happenings cause the steel to become harder? Please dig down into the micro details of the crystallites but in somewhat laymen's terms. Also describe the processes which achieve these results; if you have the time. Thanks for your time and effort.
- If you are speaking of a micro mini skirt, then i would think that the answer would be 1000 Hostess HoHo's would equal a macro skirt.
- Q: Yes, I understand it can weaken steel greatly. But can it MELT steel? (key word: melt)
- Not likely -- the melting point of steel is about 1500 degrees Celsius, while the hottest jet fuel burns at is about 825 degrees Celsius (and its usually way below that). If you're one of those people wondering why the collapse in 9/11 ... it's quite possible that the temperatures and heat inside the buildings were way about the melting point of steel in some places. But it would not be just because of burning jet fuel. And, planes carry a lot of material that can catch fire at relatively low temperatures, but which can give off a huge amount of heat (and reach high temperatures), which would contribute to melting and burning of mild steel.
- Q: My musical saw has, despite my best efforts, got little patches of rust on it. How Do I go about removing the rust without spending too much on rust-removal products and without affecting the properties of the steel?
- I would suggest rust removal by electrolysis. Search youtube for that. It probably will not affect the metal but there are no guarantees. I would run a test on another metal. Also this process can be dangerous because hydrogen gas is a by-product - remember not to smoke or be cooking nearby! The Easy way is with BlackStar Rust Remover. It will turn the metal black and convert the rust to metal which can then be painted or left black.
- Q: Is there any noticable or perceived difference between smoking out of a pipe with a brass screen and a stainless steel screen?
- Stainless Steel Pipe Screens
- Q: Can steel coils be custom-made to specific requirements?
- Yes, steel coils can be custom-made to specific requirements.
- Q: What are the different types of steel coil edges?
- Various steel coil edges exist, each possessing unique characteristics and applications. 1. Mill Edge: The most prevalent type, it is obtained by cutting the coil at the mill without undergoing any further processing or treatment. Mill edge coils have a natural, slightly rounded edge, making them suitable for a wide array of applications. 2. Slit Edge: Slit edge coils are created by cutting the coil across its width using a slitting machine. This results in a straight and smooth edge, making them ideal for precise measurements needed in automotive parts or electrical components. 3. Deburred Edge: Deburred edge coils have undergone an additional process to eliminate any burrs or sharp edges that may exist after slitting. This ensures safer handling and reduces the risk of damage during fabrication or installation. Deburred edge coils are commonly used in the construction industry, particularly for structural steel components. 4. Rounded Edge: As the name implies, rounded edge coils possess a curved edge profile achieved through a specific rolling process. This creates a smooth and curved edge, making them often utilized in applications prioritizing safety, such as the manufacturing of household appliances or kitchen equipment. 5. Sheared Edge: Sheared edge coils are produced by cutting the coil using shearing blades, resulting in a straight edge with a slight burr. While sheared edge coils may have a rougher finish compared to other edge types, they are still frequently used in applications that do not require a high level of precision, like general fabrication or shelving. In summary, the choice of steel coil edge depends on specific application requirements, including factors such as measurement precision, safety considerations, and aesthetic preferences.
- Q: Is there any way to melt steel without the intense heat of a blast furnace?
- Iron melts at a very high temperature, so if the goal is to melt it, then there will be a certain amount of intense heat of course. Steel is recycled in a carbon arc furnace. The bottom is lined in graphite. Large graphite rods are lowered into iron scrap and enormous amounts of electricity melt the iron due to the heating of the carbon due to its resistance. The carbon also removes any oxides by forming CO2. Aluminum and lead can also be recycled in this fashion. Ordinary rust can be turned into liquid iron through the use of the thermite reaction. Rust and aluminum power can be ignited with a propane toarch or a magnesium ribbon fuse. The aluminum is oxidized and the rust reduced to molten iron. This reaction is used to spot weld cracks in steel structures, like railroad tracks. It is also a popular arson device used by spies.
