Q:I want to purchase a set of knives made of carbon steel and want to be able to store them on a magnetic knife strip for handy access, I just wasn't sure if this alloy would stick to a magnet????Thanks: Yes, carbon steels are magnetic. In fact, some stainless steel knives are magnetic as well. Some stainless steel alloys are naturally magnetic and some become magnetic when they are deformed by forging or rolling (check out a deep drawn SS sink and explore where it is magnetic and where it isn't). Depending on the details, some carbon steels can be made harder than the stainless steel typically used for knives (440 alloy) but the carbon steel knives are very much more likely to suffer corrosion. hope this helps

Q:I have good quality knives that I sharpen with various things, but mostly with a fine, diamond encrusted dry stone (eze lap) . When I run them over the steel, it doesn't seem to make any difference. I've heard that it aligns the edge, whatever that means. Using a steel, is it all just for show ?: It does NOT sharpen a knife, It helps to keep a sharp knife sharp. Once you have sharpened your knife weather on a stone or other ways you should use the steel before using each time to keep it's edge . Think of an athlete who works out to gain muscles(sharpening) and stretches(steel) before using them. The show part is all in the way you use the steel, some just go downward and some go upward, either way you need to change sides of the blade on each stroke just like sharpening.

Q:What are the different types of steel coil cutting machines?: There are several different types of steel coil cutting machines available in the market, each designed to cater to specific needs and requirements. Some of the commonly used types include: 1. Slitting Machines: Slitting machines are used to cut steel coils into narrower strips. They have multiple circular blades that make precise cuts along the length of the coil, allowing for the production of narrower coils or strips. 2. Cut-to-Length Machines: Cut-to-length machines are designed to cut steel coils into specific lengths. These machines can accurately measure and cut the coil to the desired length, ensuring uniformity and precision. 3. Rotary Shears: Rotary shears are heavy-duty cutting machines that can handle thicker and larger steel coils. They use a rotating blade to cut through the coil, making it suitable for cutting thicker gauge materials. 4. Multi-Blanking Machines: Multi-blanking machines are designed to cut steel coils into multiple smaller blanks simultaneously. These machines can cut the coil into various shapes and sizes, making them ideal for producing multiple parts from a single coil. 5. Slit and Cut-to-Length Combination Machines: These machines combine the functionalities of slitting and cut-to-length machines, allowing for both narrow strip cutting and length cutting in a single process. They are versatile and efficient, saving time and increasing productivity. Each type of steel coil cutting machine has its own advantages and is suitable for specific applications. The choice of machine depends on factors such as coil thickness, desired strip width, required length accuracy, and production volume.

Q:What are the dimensions of steel coils used in the transportation equipment industry?: The dimensions of steel coils utilized in the transportation equipment sector may differ according to specific demands and applications. Nevertheless, there exist some prevalent measurements that are extensively employed. Typically, the width of steel coils used in the transportation equipment industry ranges from 600mm to 2000mm (24 to 78 inches). This width is selected to ensure compatibility with the machinery and equipment employed in transportation, such as trucks, trailers, and railcars. The thickness of steel coils exhibits significant variation depending on the specific application and desired material strength. However, common thickness ranges for steel coils in the transportation equipment industry generally fall between 0.5mm and 6mm (0.02 to 0.24 inches). The inner diameter of steel coils utilized in the transportation equipment industry is typically standardized at either 508mm (20 inches) or 610mm (24 inches). This standardization facilitates easy handling and compatibility with industry machinery. The outer diameter of steel coils can differ depending on the coil's width and thickness. Nonetheless, typical outer diameter ranges for steel coils in the transportation equipment industry generally span from 1000mm to 2200mm (39 to 87 inches). It should be recognized that these dimensions are not fixed and can be tailored to specific requirements and applications within the transportation equipment industry.

Q:What are the surface treatments for steel coils?: Steel coils have multiple options for surface treatments, each with a particular purpose and unique advantages. Some popular surface treatments for steel coils are: 1. Hot-dip galvanization: This technique involves submerging the steel coil in molten zinc, resulting in a protective layer of zinc coating on the surface. Galvanization provides outstanding corrosion resistance, making the steel coil suitable for outdoor use in harsh environments. 2. Electro-galvanization: By using an electrolytic process, a thin layer of zinc is deposited onto the steel coil's surface. Electro-galvanization offers good corrosion resistance, although the coating is generally thinner compared to hot-dip galvanization. 3. Pre-painting or pre-coating: Prior to being formed into final products, steel coils can be coated with paints or other coatings. This surface treatment enhances the coil's visual appeal while providing protection against corrosion, weathering, and other environmental factors. 4. Pickling and oiling: This treatment involves immersing the steel coil in an acid solution to remove oxides and scale from the surface. After pickling, the coil is typically coated with oil to prevent rust formation during storage and transportation. 5. Phosphating: Phosphating is a chemical conversion coating process that forms a phosphate layer on the steel coil's surface. This treatment improves the adhesion of subsequent coatings, such as paints or primers, while also offering some corrosion resistance. 6. Organic coatings: Steel coils can be coated with various organic materials, including epoxy, polyester, or polyurethane, to enhance their corrosion resistance and aesthetic appearance. These coatings provide a wide range of colors, textures, and finishes, making them suitable for diverse applications. It is important to consider the intended application, environmental conditions, and desired appearance when choosing a surface treatment for steel coils. Manufacturers and end-users must carefully evaluate these factors to select the most suitable surface treatment for their specific requirements.

Q:Why?Which one should i get? I am just starting to learn Guitar. Which one would be better for me? What is the difference? I already got the acoustic nylon but i might return it... if the steel is better.: I find for beginners nylon is better. You won't get as many blisters and nylon strings are easier to bend.

Q:Hi there! I just purchased two cookie sheets labeled as non-stick 100% carbon steel. I've never heard of carbon steel before, and I'm trying to be careful about not using certain products that are harmful to health such as aluminum and Teflon. Is this a safe metal choice for baking?: Steel Baking Sheet

Q:What are the different methods of coil flattening for steel coils?: There are several methods of coil flattening for steel coils, each with its own advantages and limitations. Some of the most commonly used methods include: 1. Roller leveling: This method involves passing the steel coil through a series of rollers that apply pressure to flatten the coil. The rollers can be adjustable to achieve the desired level of flatness. Roller leveling is a versatile method that can handle a wide range of coil sizes and thicknesses. 2. Precision leveling: This method utilizes a more sophisticated leveling machine that applies pressure on specific areas of the coil to eliminate any waviness or defects. Precision leveling is often used for high-quality steel coils that require extremely flat surfaces. 3. Stretch leveling: Also known as tension leveling, this method involves stretching the steel coil beyond its yield point, causing it to permanently deform and flatten. Stretch leveling is commonly used for thinner gauge coils and can effectively remove coil set and crossbow defects. 4. Temper rolling: This method involves subjecting the steel coil to a controlled low-temperature heat treatment followed by cold rolling. The combination of heat and cold rolling helps to relieve internal stresses and improve flatness. Temper rolling is particularly suitable for coils that require enhanced surface quality. 5. Laser flattening: This advanced method utilizes laser technology to selectively heat and flatten specific areas of the coil. Laser flattening is highly precise and can correct localized defects or unevenness, but it is typically used for smaller coils due to its higher cost. It is important to note that the selection of the most appropriate method for coil flattening depends on various factors, including the desired flatness requirements, coil dimensions, material properties, and production budget.

Q:Can steel coils be coated with zinc?: Yes, steel coils can be coated with zinc through a process known as galvanization.

Q:What is the maximum diameter of a steel coil?: The maximum diameter of a steel coil can vary depending on the specific manufacturing process and equipment used. However, in general, the maximum diameter of a steel coil can range from a few inches to several feet.
