Q: I'm planning to buy a pair of Doc Marten boots but I want some steel toed ones. I don't know if all of them are steel toed, or only some of them, or what?: mine arent steel-toed....theyre upper leather certain types of boots maybe steel-toed in case the person wearing them is in construction...

Q: I asked a question last week about stainless steel and got some great answers. I combed all over the internet to try to figure this one out but could not find anything. What resists bending better: chrome vanadium steel (i.e. a steel commonly used to make tools) or stainless steel 304. My guess would be the chrome vanadium alloy but thats just a guess. Which on resist's bending better and by how much (#'s please :-)). Also, if anyone knows if chrome vanadium steel is cheaper than stainless steel 304 that would be awesome? I can't find a price per pound on chrome vanadium steel anywhere! Please help. Thanks in advance-Josh: Type 304 stainless steel can be tempered to give tensile strength up to about 125,000 psi. There are many chrome vanadium alloys, and tempers, but they are generally very hard steels used for machine tools which are used to cut other steels. They generally are much stronger, and can be hardened up to tensile strengths of 250,000 psi and beyond. (Bending strength is proportional to tensile strength, but Cr-V steels are not usually used for beams or other structure members.) Cr-V steels are specialty alloys and will probably be a good bit more expensive per pound than common stainless alloys. For any steel, price depends on the form you are buying, i.e. plate, bar, or other shape, as well as the alloy and temper specified, and the quantity. You need to get prices from a supplier. You can find some online catalogs, but you usually have to call the vendor for price info.

Q: What are the challenges in coil leveling for coated steel?: Coil leveling for coated steel presents several challenges that need to be addressed in order to achieve high-quality, flat, and smooth coils. Firstly, one of the main challenges is the potential for coating damage during the leveling process. Coated steel coils are typically coated with materials such as zinc or paint, which can be easily scratched or marred if not handled properly. The leveling process involves passing the coil through a set of leveling rolls, which can potentially cause friction, abrasion, or other mechanical damage to the coating. Therefore, it is crucial to carefully control the speed, pressure, and alignment of the leveling rolls to minimize coating damage. Secondly, the thickness variation across the coil presents a significant challenge. Coated steel coils often have thickness variations due to inherent material properties or production processes. These variations can result in uneven leveling and can lead to coils with waviness or uneven flatness. Achieving uniform leveling across the entire coil surface is essential to ensure consistent quality and appearance of the final product. Another challenge in coil leveling for coated steel is the possibility of coil shape distortion. Coating processes can introduce stresses into the steel, which can cause the coil to warp or distort during the leveling process. This distortion can result in coils with uneven edges or inconsistent flatness. Proper control of the leveling process parameters, such as the number of leveling passes and the tension applied to the coil, is necessary to minimize shape distortion. Additionally, the coil leveling process can generate internal stresses in the steel itself, particularly in coated steels that have been cold-rolled or heat-treated. These internal stresses can cause coil spring-back, where the coil tries to return to its original shape after leveling. Spring-back can result in coils with unwanted curvature or uneven flatness. Effective strategies, such as stress relief annealing or using counteracting leveling techniques, are essential to minimize spring-back and achieve the desired flatness. Finally, the handling and storage of coated steel coils present challenges in maintaining the quality of the leveled coils. Coated steel coils are sensitive to environmental conditions such as humidity, temperature, and exposure to corrosive agents. Proper storage and handling practices are crucial to prevent coating damage, rust, or other forms of deterioration that can occur during transportation or storage. In summary, the challenges in coil leveling for coated steel include minimizing coating damage, addressing thickness variation, controlling shape distortion and spring-back, and ensuring proper handling and storage. Overcoming these challenges requires precise control of process parameters, the use of appropriate leveling techniques, and adherence to strict quality control measures throughout the entire process.

Q: How are steel coils used in the production of food processing equipment?: Steel coils are commonly used in the production of food processing equipment due to their various advantageous properties. These coils, typically made from stainless steel, are used in the manufacturing of a wide range of equipment such as mixers, blenders, conveyors, ovens, and fryers. One of the main reasons steel coils are used in food processing equipment is their excellent resistance to corrosion. Stainless steel coils are highly resistant to rust and can withstand exposure to moisture and various food substances without deteriorating. This is crucial in ensuring the equipment remains hygienic and safe for food processing. Additionally, steel coils provide exceptional strength and durability, allowing food processing equipment to withstand heavy use and harsh operating conditions. The coils can be formed into different shapes and sizes, enabling the fabrication of complex equipment components. This versatility facilitates the design and construction of equipment that is both efficient and reliable in processing various food products. Furthermore, steel coils are easy to clean and maintain. The smooth surface of stainless steel makes it resistant to staining and facilitates the removal of food residues, preventing the growth of bacteria. Regular cleaning and sanitization of food processing equipment are essential for maintaining food safety standards, and steel coils make this process easier and more effective. Moreover, steel coils have excellent heat conductivity properties, allowing for efficient heat transfer in food processing equipment such as ovens and fryers. This enables precise temperature control and uniform cooking, ensuring consistent quality of processed food products. In summary, steel coils play a vital role in the production of food processing equipment by providing corrosion resistance, strength, durability, ease of cleaning, and efficient heat transfer. These qualities make steel coils an ideal material for manufacturing equipment that meets the high standards of hygiene, safety, and quality required in the food processing industry.

Q: Is there a type of spray paint that would work on Stainless steel?That would also be permenant or at least make it through a wash or two?: I've also learned something today! Good luck and have fun!

Q: Or is it a coating that is applied? If so what types of steel? Or what types of coatings?: there is a weathering steel that corrodes and then stops. The outer surface of the steel is a rusty looking brown but after the first layer of rust appears, the process stops. It used to be called A588 steel. So called mild steel is not A36 anymore, it is A992 (50 ksi yield). The only material that is A36 anymore are angles, channels, and plate. You can coat the steel with an epoxy coating to protect the steel from this highly corrosive environment. Google a company called TNEMEC. They offer epoxy coatings for steel and other coatings. Weathering steel and epoxy coating are not cheap options.

Q: How are steel coils used in the manufacturing of wind turbines?: Steel coils are used in the manufacturing of wind turbines to create the main structural components, such as the tower and the nacelle. These coils are shaped and welded to form the strong and durable framework that supports the turbine's blades and houses the generator. Additionally, steel coils are also used to fabricate other essential parts, such as the hub and the base, ensuring the stability and efficiency of the wind turbine.

Q: What are the weight ranges of steel coils?: The weight of steel coils can differ based on their dimensions and intended purpose. In general, steel coils can weigh anywhere from a few hundred pounds to several tons. For instance, hot-rolled steel coils generally fall between 10 and 25 tons, while cold-rolled steel coils can range from a few hundred pounds to 20 tons. The weight of steel coils is also influenced by factors like coil thickness, width, grade, and steel type. Ultimately, the weight range of steel coils is determined by the industry and application requirements.

Q: I want to replace the old refrigator within the next 6 months........ Is the trend to buy a stainless steel refrigerator? Some magazines and internet sites are pointing me that direction. What are the pro's and con's ? I like the color bisque, or cream-color as well, or better, than stainless steel. What would be the reasons to buy stainless steel...is it becoming the most popular color ?: It's not about color necessarily. Stainless steel is easier to clean and for the most part scratch resistant. It's easier to take care of.

Q: what is the porpose of preheating mild steel prior to welding: :you could attempt welding with whats pronounced as a filler rod. you could weld with the a million/8 rod interior the welder stinger and by conserving the a million/sixteen rod in the different hand, upload it as you weld.
