Q: I am in the market for a good hunting knife under $100. I am primarily looking for a knife that will keep it's edge. What type of steel should I be looking for?: Regardless of who makes the knife, you might look at stainless steel instead of the better tool steels like O2,M2 or D2...stainless takes more abuse and neglect than the others do.

Q: I want to save water $$, so I want to use frozen steel to cool my coke. possible or no?: If you put steel in the freezer, allow it to cool to 32 degrees and then put it in water a transfer of heat will occur and the water will cool off. How much and how quickly, I don't know. I believe the Mythbusters did experiments on something like this. If it were economical, we woud see steel ice cubes being sold instead of ice makers.

Q: I'm looking for the weight of different types of steel and haven't found anything helpful!!thank you: Category Material Density Metal Steel, tool 7.715 Metal Wrought Iron 7.75 Metal Carbon Tool Steel 7.82 Metal Steel, cold-drawn 7.83 Metal Carbon Steel 7.84 Metal Steel, C1020, HR 7.85 Metal Pure Iron 7.86 Metal Soft Steel (0.06% C) 7.87 Metal Stainless Steel, 304 8.03 Metal Stainless 18Cr-8Ni 8.03 I looked up specific gravity mild steel. This might get you pointed in the right direction.

Q: What are the main factors that affect the flatness of steel coils?: The main factors that affect the flatness of steel coils include the quality of the raw material used, the thickness and width of the coil, the temperature and humidity during the manufacturing process, the tension applied during coiling, and the cooling and leveling processes employed.

Q: What are the dimensions of steel coils used in the construction equipment industry?: The dimensions of steel coils used in the construction equipment industry can vary, but they are typically around 48 to 72 inches in width and have an outer diameter of 60 to 80 inches. The weight of these coils can range from 5,000 to 30,000 pounds.

Q: What are the common methods of recoiling steel coils?: Manufacturers and customers have various options when it comes to recoiling steel coils. One frequently used method is slitting, which employs rotating circular blades to cut a wide steel coil into narrower strips. This results in multiple smaller coils with desired widths. Slitting is commonly employed to create coils of different sizes for diverse applications. Another technique is known as cut-to-length (CTL) recoiling, where the steel coil is cut into specific lengths according to the customer's requirements. This involves passing the coil through a straightening and leveling machine, followed by a flying shear that cuts the steel into the desired lengths. CTL recoiling is particularly useful in industries that demand precise and uniform steel lengths, such as construction or automotive. Furthermore, there is a method called coil-to-coil recoiling. This process involves rewinding the steel coil onto a new coil with the desired dimensions and properties. Coil-to-coil recoiling is typically utilized when the original coil needs resizing, reconditioning, or rerolling for further processing or transportation purposes. Specialized recoiling machines ensure proper tension, alignment, and winding of the steel coil onto the new coil. In conclusion, the recoiling of steel coils can be accomplished through various methods, including slitting, cut-to-length recoiling, and coil-to-coil recoiling. Each method offers its own advantages and is chosen based on factors such as required coil dimensions, precision, efficiency, and the specific needs of the industry or customer.

Q: How are steel coils used in the production of signage?: Steel coils are used in the production of signage by being cut into sheets and then shaped into various sign components. These coils provide a durable and rigid material that can be easily manipulated and formed into different shapes, allowing for the creation of sturdy and long-lasting signs.

Q: Can steel coils be coated with thermally insulating materials?: Yes, steel coils can be coated with thermally insulating materials. These materials help to reduce heat transfer and provide insulation to the steel coils, enhancing their thermal resistance.

Q: What are the different methods of roll forming steel coils?: There exists a variety of techniques for roll forming steel coils, each possessing distinct features and uses. Some prevalent methods encompass: 1. Conventional Roll Forming: This technique, widely employed, involves gradually shaping a continuous steel strip into the desired profile by passing it through a series of rollers. It offers high precision and repeatability, making it ideal for manufacturing intricate shapes and profiles. 2. Pre-Punch and Cut: With this method, the steel strip is pre-punched with holes or slots before undergoing roll forming. This facilitates easier cutting and shaping during the forming process, enhancing efficiency and reducing waste in specific applications. 3. Post-Punch and Cut: Similar to pre-punching and cutting, this method adds holes or slots after the roll forming process. It provides greater flexibility in creating customized shapes and designs since the holes can be precisely placed as required. 4. Post-Forming: On certain occasions, the steel strip is initially roll formed into a basic shape or profile, which is then further manipulated or formed. This approach allows for additional customization and enables the creation of more intricate geometries. 5. Progressive Roll Forming: This technique involves continuously passing the steel strip through a series of rollers, with each roller gradually adding a distinct feature or forming a specific part of the final profile. Progressive roll forming is commonly utilized for lengthy, continuous profiles with repetitive shapes. 6. Incremental Roll Forming: In this method, the steel strip is incrementally shaped by means of small movements of the rollers. It provides greater flexibility in shaping complex profiles and proves particularly useful for producing prototypes or low-volume production runs. Ultimately, the selection of a roll forming method depends on the specific requirements of the application, such as the desired shape, complexity, precision, and production volume. Each method presents its own advantages and limitations, and manufacturers typically choose the most suitable technique based on these factors.

Q: Is there a chemical that can be applied (spraid, brushed, adhere) to a steel surface to decrease the heat conductive properties of the metal (so it doesn't heat up as quickly)?Thanks in advance!: There is, but I don't know what it is made out of. It is probably some fireproof, foam material which acts like insulation. I doubt it is designed to resist abrasion however. Most things which adhere to metal surfaces are not flameproof, and those which do resist fire are not good insulators. For example, the ceramic coating of appliances like stoves and washing machines adhere very well and are fire resistant, but do not insulate. It was the failure of the steel insulation which caused the collapse of the world trade centers. The impact of the airplane tore away all the insulation on the supporting struts of the building and then the fire caused the steel to soften and break. Steel was once insulated by wrapping it in asbestos cloth and then applying plaster over this to form a shell. It did not actually adhere to the steel but it did insulate it, and was fireproof. However asbestos is a cancer hazard and a lot of old buildings are being stripped of their asbestos as a safety precaution. The asbestos can be replaced with fiberglass which is usually duct taped together.
