Q: I'm a big fan of stainless steel and sterling silver, but not of the humidity of the country I'm in. Therefore I sweat more. Gross, I know. I'm buying a necklace chain for my ring.So does sweat contribute to tarnishing of silver and steel? The real kind?: steel shouldn't really tarnish, it rusts and moisture increases that. Silver tarnishes when exposed to air and sulfur. Moisture increases the process a bit, but it happens anyway. Sweat is not gross, it's a necessary function of your body, otherwise you would die. A lot of sports people wear jewelry and they sweat a lot. If you wear the jewelry all the time, that will prevent the tarnish a bit. If you take it off, clean it (water and dish washing liquid), dry it and put it in a zip lock back to keep it away from air and moisture. In the end, cleaning the jewelry is quick and easy so don't worry about it.

Q: How are steel coils used in the production of metal furniture?: Steel coils are used in the production of metal furniture as they are the primary raw material for manufacturing various components such as frames, legs, supports, and brackets. These coils are unrolled and passed through different machinery to shape and cut them into the desired sizes and shapes. The resulting pieces are then welded, joined, or assembled to create the different parts of the furniture. The strength and durability of steel make it an ideal material choice for metal furniture, ensuring sturdy and long-lasting products.

Q: What are the challenges in coil leveling for coated steel?: To achieve high-quality, flat, and smooth coils, several challenges must be addressed in the process of coil leveling for coated steel. The first challenge lies in the potential damage to the coating during leveling. Coated steel coils are typically covered with materials like zinc or paint, which are susceptible to scratching or marring if mishandled. The leveling process involves passing the coil through a series of rolls, which can cause friction, abrasion, or other mechanical harm to the coating. Therefore, it is crucial to meticulously control the speed, pressure, and alignment of the rolls to minimize coating damage. The second challenge stems from the variations in thickness across the coil. Coated steel coils often exhibit thickness discrepancies due to inherent material properties or production methods. These variations can lead to uneven leveling, resulting in coils with waviness or inconsistent flatness. Achieving uniform leveling across the entire coil surface is vital to ensure consistent quality and appearance of the final product. Another challenge in coil leveling for coated steel is the possibility of shape distortion. The coating processes can introduce stresses into the steel, causing the coil to warp or distort during leveling. This distortion can lead to coils with irregular edges or uneven flatness. Proper control of leveling process parameters, such as the number of passes and applied tension, is necessary to minimize shape distortion. Furthermore, the coil leveling process can generate internal stresses in the steel, especially in cold-rolled or heat-treated coated steels. These internal stresses can result in coil spring-back, where the coil attempts to revert to its original shape after leveling. Spring-back can cause coils with undesired curvature or inconsistent flatness. Effective strategies, such as stress relief annealing or employing counteracting leveling techniques, are essential to minimize spring-back and achieve the desired flatness. Lastly, handling and storing coated steel coils pose 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 substances. 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 conclusion, the challenges in coil leveling for coated steel involve minimizing coating damage, addressing thickness variation, controlling shape distortion and spring-back, and ensuring proper handling and storage. Overcoming these challenges necessitates precise control of process parameters, the application of suitable leveling techniques, and strict adherence to quality control measures throughout the entire process.

Q: I know this is an alloy, but can it be mixed to form a superior steel? Therefore less likely to stain?: Unfortunately the stainless property does not make a 100% superior blade, unless you are not too concerned with how it performs. Generally speaking the mineral that allows steel not to stain is chromium so the higher content of chromium the more shiny and less likely to stain. The best performing blades however are the ones resistant to fatigue that usually contain high silica levels like japanese blades. Chromium on the other hand does make a less flexible and lower quality blade that also needs to be thicker, so it comes down to what will you be using it for.

Q: What are the common certifications required for steel coils?: The certifications needed for steel coils differ based on the industry and purpose of the coils. However, there are various certifications that are commonly requested. 1. ISO 9001: This certification ensures that the manufacturer has established a quality management system that meets global standards. It confirms that the manufacturer has the necessary procedures and controls in place to consistently produce high-quality steel coils. 2. ISO 14001: This certification concentrates on environmental management systems. It guarantees that the manufacturer is dedicated to minimizing its environmental impact and reducing waste during the production process. 3. ISO 45001: This certification relates to occupational health and safety management systems. It ensures that the manufacturer has implemented measures to safeguard the health and safety of its employees and stakeholders. 4. ASTM International Standards: The American Society for Testing and Materials (ASTM) has introduced various standards for steel coils. These standards include chemical composition, mechanical properties, and dimensional tolerances. Adhering to these standards guarantees that the coils meet the specified requirements and are suitable for their intended use. 5. EN Standards: The European Committee for Standardization (CEN) has developed a series of standards for steel coils, known as EN standards. These standards cover similar aspects as ASTM standards but are specific to the European market. 6. JIS Standards: The Japanese Industrial Standards (JIS) are widely used in the steel industry in Japan and other Asian countries. Complying with JIS standards ensures that the coils meet the specific requirements of the Japanese market. 7. Certifications specific to products: Depending on the application of the steel coils, additional certifications may be necessary. For instance, if the coils are intended for automotive use, certifications like ISO/TS 16949 (Quality Management Systems for the Automotive Industry) may be required. It is crucial to note that the specific certifications needed may differ based on the region, industry, and customer requirements. Manufacturers should consult their customers and industry standards organizations to determine the exact certifications necessary for their steel coils.

Q: Does the solution change, or does only the steel wool change color?: Steel is an iron alloy, and iron is more reactive than copper, so what you'd see is the blue colour of the solution becoming lighter, and a black precipitate appearing on the steel wool.

Q: Can steel coils be coated with fire-resistant materials?: Yes, steel coils can be coated with fire-resistant materials.

Q: How much should someone sell a 6 ft stainless steel counter? How about one with a sink?: Sheet stainless steel is about $2.00 to $2.75 per lb. in the US right now for a 2B stainless steel without any special finish. The cost of a sink or counter is going to vary widely. The labor to fabricate it is going to be a lot higher than the material cost so the price per pound is not going to tell you much. In California a custom 6' counter would be somewhere between $1,200 and $3,000. A standard size single compartment sink would be about half of that.

Q: I have my grandpa's navy knife from ww2, a mk2 combat knife i think, and i was wondering what type of steel it is made of. I'm guessing it's a high carbon steel, i'd just like to know exactly what grade.: I would get a 1095, serrated edge, tanto style, with either a good quality rubberized or bone handle.

Q: What is the standard weight of steel coils?: The standard weight of steel coils can vary depending on the specific type and dimensions of the coil. However, a common range for steel coils is between 3 to 25 tons.
