- Q: What are the different types of steel coil cutting methods?
- There are several different types of steel coil cutting methods, including shearing, slitting, and laser cutting. Shearing involves using a straight blade to cut through the coil, while slitting involves using circular blades to make multiple cuts. Laser cutting is a more precise method that uses a laser beam to cut through the coil. Each method has its advantages and is chosen based on the specific requirements of the project.
- Q: How are steel coils used in the manufacturing of shipping containers?
- Steel coils are used in the manufacturing of shipping containers to provide strength, durability, and structural integrity. These coils are processed and shaped into the necessary components, such as walls, floors, and roofs, which are then assembled to create a sturdy container. The steel coils also allow for easy transportation and stacking of the containers, ensuring safe and efficient shipping of goods worldwide.
- Q: How are steel coils inspected for width using laser measurement?
- Steel coils are inspected for width using laser measurement by placing a laser sensor on one side of the coil and a reflective target on the other side. The laser beam is emitted towards the target, and the reflected beam is analyzed by the sensor. Based on the time it takes for the beam to travel back and the angle of the beam, the width of the steel coil can be accurately measured.
- Q: I have a set of Ben Hogan Apex Plus Forged Irons, how can i figure out if the shafts are steel or graphite?
- Steel will look like polished steel. And Graphite or CF will be painted or clear over the black CF fibers. Basically - if it looks like steel it is. You could look up you clubs on google also. Many times the shafts have the material, stiffness and other info printed right on them.
- Q: What are the different methods of heat treatment for steel coils?
- There are several different methods of heat treatment for steel coils, each with its own benefits and applications. 1. Annealing: This method involves heating the steel coils to a high temperature and then slowly cooling them, usually in a controlled atmosphere. Annealing helps to relieve internal stresses, improve ductility, and refine the grain structure of the steel, making it softer and more machinable. 2. Normalizing: Normalizing is similar to annealing, but the cooling process is typically faster. This treatment is often used to refine the grain structure and achieve a more uniform hardness throughout the steel coils. It also helps to remove any residual stresses and improve the mechanical properties of the material. 3. Quenching and tempering: In this two-step heat treatment process, the steel coils are first heated to a high temperature and then rapidly cooled by immersion in a quenching medium, such as oil or water. This causes the formation of a hard, brittle phase called martensite. To improve the toughness and reduce the brittleness, the coils are then reheated to a lower temperature and held there for a specific period of time. This process, known as tempering, helps to reduce the internal stresses and increase the ductility and toughness of the steel. 4. Case hardening: Case hardening is a heat treatment method used to increase the surface hardness of the steel coils while maintaining a relatively soft and ductile core. The process involves heating the coils in the presence of a carbon-rich atmosphere, allowing carbon to diffuse into the surface layer of the steel. This creates a hard outer layer, known as the case, while preserving the desired mechanical properties in the core. 5. Stress relieving: Stress relieving is performed by heating the steel coils to a specific temperature and holding them there for a sufficient period of time. This process helps to reduce residual stresses that may have been introduced during previous manufacturing or heat treatment processes. Stress relieving can improve dimensional stability, reduce the risk of distortion or cracking, and enhance the overall performance of the steel coils. Overall, the choice of heat treatment method for steel coils depends on the desired properties, intended application, and specific requirements of the end product. Each method has its own advantages and can be tailored to achieve the desired balance between hardness, toughness, ductility, and other mechanical properties.
- Q: I am getting a barn soon and I was debating between wood, and steel. I think steel would look nicer [painted of course] and I was wondering which is cheaper. Any extra info would be great. Thanks x

- Q: Have spent two days making a specialized knife out of 304 stainless steel, after throwing into a log it bent slightly arghhhh. Is it worth continuing to finish it off or start all over again with different kind of steel if so which kind should i use.
- Sorry okorder /... I hope that link works but as you can see you dont want to use 303.304.316,410,416,430 You can get away with 301 but would be best to use 440. It kind of sounds like your a home shop guy. It would be best for you to make a knife out of a1 or d2 tool steel. with these steels you can torch heat them to a red hot heat where a magnet will not stick to them. Then let them cool slowly in the air. After that you can temper in a oven around 400f. This will a very hard long lasting knife. Check OKorder for good steel prices. A1 and D2 are not stainless but they are the best for a home shop. If you go stainless you can buy preharden material but you will have to grind everything. You can also pay someone to harden your knife but dont plan on it being cheap.
- Q: I feel really stupid asking this question but i feel like a put metal/steel strings on my classical guitar how do you tell the difference?
- you do NOT want to put steel strings on a nylon string guitar, it will ruin it. It does get a little confusing. With steel strings, all 6 strings are metal. (usually steel, but not always, nickel, copper may be used too) And they use a steel core. with nylon strings, the high 3 strings, are obviously nylon/plastic. the 3 bass strings look metal, but they have a silk type core, with metal wrapped around it. The steel strings have a LOT more tension,, they can break the plastic tuners, beak the nut, pull the top up, and pull the bridge off, If you're not sure yet, have a real music store explain it, not a toy store, or costco or walmart.
- Q: which is the most tough and durable steel type ??
- C'mon. Really? That's your question? How about some actual details like the application, is it going to be formed into a shape, do you need to weld it, what type of environment like corrosion and temperature is it going to be subject to? There are roughly 2,000 grades of steel and a couple hundred grades of stainless steel. Steels can be soft or they can be exceptionally hard. We need more info please.
- Q: Im looking at some knives and am wandering if they use good steel one is this case knife and its 54 dollars Do they use good steel or not Iv never had a good experience with Case but am wandering if they use good steel now? if you all have any other recommendations let me hear them I got my Selection from here so any others wont hurt. so basic break down does case use good steel know?
