- Q: benchmade mpr with m390 steel knife. Is it better than d2 s30v or 154cm steel?
- From what I read M390 is relatively wear resistant, with very high stain resistance and good toughness. It is quite hard to qualify steel as better than other steel because it depends on many factors. E.g. for a small folder designed for delicate cutting D2 at high hardness would perform better, but if the environment is corrosive, like saltwater then M390 would be better. I'm not so sure about using stainless steels in large chopping style knives, but I've seen M390 used for them as well. Obviously hardness had to be lowered, which reduces edge holding ability, especially at low angles. Overall, it's a good steel, but if it will outperform S30V or D2 or 154Cm depends on heat treatment and blade geometry, knife designed use, etc.
- Q: How are steel coils welded together?
- Steel coils are typically welded together using one of two methods: either by resistance welding or by arc welding. In resistance welding, the coils are pressed together and an electric current is passed through them, generating heat and causing the coils to fuse together. Arc welding, on the other hand, involves the use of an electric arc that melts the edges of the coils, creating a molten pool. As the pool solidifies, the coils bond together, forming a strong weld. Both methods ensure a secure and durable connection between the steel coils.
- Q: What are the different types of steel coil packaging?
- Various industries use different methods to package steel coils. Some common types include: 1. Wooden Crates: Steel coils are often placed in wooden crates for transportation and storage. These crates effectively protect against damage and ensure secure transit. 2. Steel Frame Bundles: Steel coils are tightly strapped together using steel bands or wires, creating a sturdy bundle that can be easily lifted and moved with cranes or forklifts. This method is suitable for vertical stacking. 3. Steel Strapping: Steel coils can also be packaged using steel strapping. Straps are tightly wrapped around the coils to secure them in place, providing protection against movement and damage during transportation. 4. VCI (Volatile Corrosion Inhibitor) Packaging: VCI packaging is ideal for preventing corrosion during storage and shipment. The coils are wrapped in special VCI film or paper that releases corrosion-inhibiting molecules, ensuring the coils remain rust-free. 5. Cardboard Packaging: Smaller steel coils or those needing extra protection can be packaged in cardboard boxes or cartons. The coils are placed inside and the box is sealed, creating a barrier against damage and contamination. 6. Stretch Wrapping: Plastic film is tightly wrapped around the steel coils, creating a secure and protective layer. This method is useful when coils need protection from dust, moisture, or other external elements. The choice of steel coil packaging method depends on factors such as size, weight, transportation requirements, and desired level of protection. Each method offers its own advantages and is chosen based on industry needs and coil specifications.
- Q: I don't know why but I'm having a VERY difficult time finding the melting point of 1008 steel.
- It is still the same for 1008 steel. Go to the bottom and see the listing of the grades it covers. Since the only difference between the 1006 and 1008 steel is a few micro amounts of alloys and by far the greatest majority or main component is iron (99%), as a general melt temperature , 2750 F is the melt temperature at which the other alloys are added to the charge to fine tune the mix. Just like adding salt to distilled water actually lowers the boiling point of water, adding alloys to iron decreases the melting point of iron. The iron melts at 2800F, but once alloys to make the 1008 grade are added, it decreases melt temp to 2750F. Since the melting point of pure iron is 2800F, the temperature is actually decreased by adding these impurities of alloys. These alloys are tested while the mix is starting to come down from a pure melt, steel is sampled. and then alloys below are checked and added to make the 1008 steel. The steel is maintained at 2750 F so that the less volatile alloys don't boil off before combining with steel. Minimum Properties Ultimate Tensile Strength, psi 43,900 - 51,900 Yield Strength, psi 26,100 - 34,800 Elongation 42 - 48% Chemistry Iron (Fe) 99% Carbon (C) 0.08% Manganese (Mn) 0.6% max Phosphorus (P) 0.035% max Copper (Cu) 0.2% min Sulfur (S) 0.04%
- Q: How are steel coils inspected for weldability using welding tests?
- Steel coils can be inspected for weldability using a variety of welding tests. One common method is the bend test, where a section of the coil is cut and bent to evaluate the quality of the weld. This test helps determine if the weld is brittle or contains any defects that could compromise its integrity. Additionally, the guided bend test is performed to assess the ability of the weld to withstand bending without cracking or breaking. Another technique used is the macro etch test, where a sample is prepared by cutting a cross-section of the coil and then etching it with a chemical solution. This test helps reveal any imperfections or inconsistencies in the weld, such as porosity, slag inclusions, or lack of fusion. Furthermore, the hardness test is conducted to measure the hardness of the weld. This is important as excessive hardness can lead to cracking or brittleness, while insufficient hardness may result in weld failure under certain conditions. Additionally, non-destructive testing methods like ultrasonic testing, magnetic particle inspection, or radiographic examination can also be employed to detect any internal defects, such as cracks or voids, in the steel coil welds without damaging the material. These welding tests are crucial in ensuring the quality and weldability of steel coils before they are used in various applications. By conducting thorough inspections, any potential issues can be identified and addressed, ensuring that the steel coils meet the required standards for weldability and structural integrity.
- Q: What are the common coil slitting methods?
- The common coil slitting methods include rotary shear, loop slitting, and double knife slitting.
- Q: How are steel coils used in the manufacturing of automotive accessories?
- Steel coils are used in the manufacturing of automotive accessories as they are processed and shaped into various components such as brackets, frames, and supports. These coils are typically cut, molded, and stamped into specific shapes before being assembled into the final product, adding strength and durability to the accessories.
- Q: How are steel coils used in the manufacturing of railway tracks?
- Steel coils are used in the manufacturing of railway tracks as they are processed into long, continuous lengths of steel rails. These coils are first uncoiled and then passed through a series of machines that shape, cut, and weld them together to form the required lengths and profiles of railway tracks.
- Q: I am a beginner and have a slow to average swing speed. Should i get graphite or steel shafts for my irons and does it make a difference?
- I agree with Matt C. I owned both steel shafted and graphite shafted irons (Callaway BB 06 Graphite and Taylor Made R7 Draw Steel). My club head speed is 75 to 80 mph. I switch to steel to graphite because i gain yards at least 15 to 20 yards more. My 9 iron (graphite) is a 150 club and my 7 iron in steel shafted. So my advice is to try both and see which one is best suited for you.
- Q: How are steel coils inspected?
- Steel coils are inspected through various methods such as visual inspection, dimensional measurement, and non-destructive testing techniques. Visual inspection involves the examination of the coils for any surface defects, such as scratches, dents, or rust. Dimensional measurement ensures that the coils meet the required specifications in terms of thickness, width, and diameter. Non-destructive testing techniques like ultrasonic testing, magnetic particle inspection, and eddy current testing are used to detect any internal defects or discontinuities in the steel coils without causing any damage to the material. These comprehensive inspection methods ensure the quality and integrity of steel coils before they are used in various industries.
