Q: What are the quality control measures for steel coils?: Quality control measures for steel coils typically include various inspections and tests to ensure that the coils meet the required standards and specifications. These measures often involve visual inspections to identify any surface defects or irregularities, such as cracks, dents, or scratches. Additionally, dimensional checks are performed to verify the coil's size, shape, and weight. Other quality control measures may involve conducting mechanical tests, such as tensile strength and hardness tests, to assess the strength and durability of the steel coils. Overall, these measures aim to guarantee that the steel coils are of high quality and suitable for their intended applications.

Q: I looking at replacing a few of the panels on my car with either Carbon Fiber or High Tensile Steel to shave off some weight and increase mpg and take some time off my quarter mile. Which is better: Carbon Fiber or High Tensile Steel?: There's different types of strength. Linear strength, the carbon fiber is stronger and more resilient. It's also much lighter, as much as 1/10th the weight of an aluminum body panel (which is lighter than steel). So, by using steel body panels, you would actually likely be ADDING weight to your car. Carbon fiber parts, of course, usually cost 2-3 times as much as their aluminum counterparts. Needless to say, consider the alternative. You can get an aluminum fender, have it be lighter than the steel part, not quite as light as the carbon fiber, but for the price of 1 carbon fiber fender, you could have a both front fenders and the hood in aluminum. Also, for the 1/4 mile, every 100lbs will drop 1/10th of 1 second off your time, which can be lost by screwing up your launch, or in other words, yo won't notice it. As for fuel economy, you won't notice a difference of more than .1-.2mpg. I know this first hand.

Q: How can I arbitrate quality of steel before purchasing it??: The quality of the alloy can be very well be judged by its appearance and lustrous surface. The more luster on the surface the more refine will the steel be. To judge its tenacity and endurance, the alloy can be subjected to a series of procedures involving stress and shock. The reaction to these processes can determine whether the steel be fit for the purpose required.

Q: I understand that Stainless Steel is a low carbon steel having minimum 10.5% chromium content in it there r 60 different type of stainless steel. Kindly informa) Is this info correct?????b) Which stainless steel can get rusted or can have superficial rust????: Stainless steel is a generic term for a whole range (there are more than 60 types) of Fe-Cr alloys. They all contain some amount of C and some alloys include a good number of other alloying elements. In almost all cases, the materials have corrosion resistance due the Cr atoms that are in solid solution with the Fe matrix. Under corrosive conditions, the Cr forms a thin tight coherent layer of Cr-oxide. This Cr oxide coating prevents further corrosion so long as it is not chemically or physically removed. If the SS has been subject to mechanical abrasion, the corrosion resistance can sometimes be restored by a light exposure to nitric acid which passivates the surface, restoring the Cr-oxide layer. The carbon content is an important factor in corrosion preformance but so is the heat treatment. Under the wrong conditions and in different environments, all SSs can rust. One of the most common corrosion problems is sensitization which occurs in the heat affect zone (HAZ) around welds. If the C content is high enough and the heat is high enough, the Cr atoms in solid solution form Cr-carbides and are no longer available to form a protective Cr-oxide. The corrosion resistance can be restored by appropriate heat treatment.

Q: Cast steel welding: I Use these for cast iron, www.yms .uk/welding-rod-small-pack/2.5mm-cast-iron-welding-rod-small-pack/1951/11612/detail.asp they are expensive when compared to welding rods for steel but i find that normal steel ones dont work on cast iron

Q: I expect that I will be questioned about my knowledge in methoding for steel castings, in a interview. I dont know about it. Can someone explain me in simple language and give me some links, like how I can explain methoding for steel castings.....key points...help please...so that i will pass the interview as if I have experience in methoding....thanks: It is very difficult to define Methoding of Steel castings by one sentence. Actually it encompasses the total casting process. Normally it would mean a) Pattern design i.e. what type of pattern it would be- wooden, metallic, split or full, loose or fitted on a match plate or any other, how will be the parting line. b) Design of the gating system. c) Design of risering i.e. numbers, size and location of risers. d) Design of molding process i.e. sand system to be used, mold box size. But to do justice to the above mentioned activities, you need to consider other parameters of the casting process such as chemical composition, solidification characteristics, pouring temperature, pouring time, knock out time etc. As I said Methoding of Steel castings means designing of the total casting process from inception to final product.

Q: i would like to make a dmascus steel knife, i have the cable but im not sure if its damascus steel or not, how do i tell? and if it isnt damascus steel how do i make a bar of it?: Here's what you need, the cable should be a minimum of 9/16 with large wires. You need some borax (20 mule team from the store). A good hot coal, coke, or gas forge. If the cable has fiber rope in the center it will need to be removed. Fuse the ends of the cable to keep them from coming apart. I use my welder and while I'm at it I weld a handle to make it easier. Heat it in the forge when the forge is properly heated, rotate it. Some people will burn the oil out, but I've found that the forge does that just fine. Rotate the cable while it's heating. When it begins the turn red pull it out and sprinkle the borax over it, don't hold back use a lot. It will begin to melt and bubble into the steel. Put the cable back in the forge, rotate and watch. This is the critical part. When the steel starts to turn from orange/yellow to almost yellow/white take it out and lightly (I use a 2lb hammer) begin hammering the cable into a square or rectangle. If you do it right you'll notice that it will begin to fight the hammer, that's when you know the weld it taking place. You'll have to repeat the process down the length of the cable. Once you have the billet made you can begin the process of shaping the edge and tang. Once you have it shaped, follow proper forge procedure then grind all the yuck off and finish shaping. Then harden and temper and finish it out. Good luck. I almost forgot a very important part. Befor you start hammering put the cable in a vice while at welding temp (if you are strong you can use a couple of plyers) and twist it tight. On the next heat hold the cable in your left and and lay it on the anvil. Concentrate on your light hammer blows being on your side of the cable. This forces the cable strands together. If you are using smaller cable like 9/16 you can double the cable up and weld two peices together, it is easier and makes for a prettier blade. Doing this you don't have to worry about twisting the cable and you can hit it much harder to start with.

Q: is broken steel the only fallout dlc that will raise the level cap from 20 to 30? also do i have to complete the main quest to play it? which fallout dlc do you think would be the best to get?: Yes, Broken Steel is the only DLC that raises your level cap. Yes, you have to complete the main quest to play it. It's kind of a prologue to the events of the ending. If you don't have the DLC and complete the game it just ends and you can't play it anymore. With the DLC you'll be able to continue playing. As for which one to get, that's your preference. Most people like the Broken Steel because it has to do with the main story and it raises the level cap - so that's the one I'll suggest to you. I also think The Pitt and Point Lookout are worth getting as well. Mothership Zeta is the one I liked least. I thought it was kind of stupid, to be honest. Operation Anchoarge is a simulation and it's pretty fun, but I don't think it's worth the $9.99.

Q: What are the different types of steel coil edge conditions?: There exist various steel coil edge conditions, each tailored to specific needs and uses. The most prevalent categories are as follows: 1. Mill Edge: The default edge condition for hot-rolled steel coils, wherein the edges remain untouched after the rolling process. This condition is characterized by a slightly rough and uneven surface. 2. Slit Edge: Achieved by cutting the coil across its width to obtain narrower strips. This condition is typically smoother and more uniform than mill edge, making it ideal for applications requiring a clean and precise edge. 3. Trimmed Edge: Achieved by eliminating irregularities and imperfections from the coil's edges. This process yields a straight and smooth edge, suitable for applications necessitating a precise and uniform surface. 4. Deburred Edge: Created by removing burrs or sharp edges from the coil. Commonly used in safety-oriented applications to eliminate potential hazards associated with sharp edges. 5. Round Edge: Attained by rounding the corners of the coil. Often employed in applications requiring easy handling or when preventing damage to other materials or surfaces is crucial. 6. Slit and Deburred Edge: Combines the advantages of both slit and deburred edge conditions. Involves cutting the coil into narrower strips and subsequently removing any burrs or sharp edges, resulting in a clean and safe edge. Each of these edge conditions serves a distinct purpose and is selected based on the specific requirements of the application. By comprehending the various types of steel coil edge conditions, one can choose the most appropriate option to ensure optimal performance and safety.

Q: How are steel coils inspected for flatness using optical sensors?: The process of inspecting the flatness of steel coils involves the use of optical sensors, which are part of a system known as optical flatness measurement. This system employs high-resolution cameras to capture images of the steel surface as it passes through the inspection line. To begin, the steel coil is unwound and conveyed over a roller table. While in motion, the optical sensors are positioned above the coil to capture images at regular intervals. These sensors are typically a combination of laser line projectors and high-resolution cameras. The laser line projectors emit a thin, straight line of laser light across the width of the steel coil. This laser line serves as a reference plane for measuring the flatness of the steel surface. Subsequently, the high-resolution cameras capture images of the laser line interacting with the steel coil. The captured images are then subjected to analysis using advanced image processing algorithms. These algorithms examine the deformation of the laser line on the steel surface and calculate the deviations from the flat reference plane. These deviations indicate any irregularities or variations in the flatness of the steel coil. The optical sensors possess the capability to accurately detect even the most minute deviations in flatness, measuring them in micrometers or smaller units. This enables manufacturers to identify and correct any flatness issues in the steel coils before further processing or shipment. In addition to measuring flatness, optical sensors can also identify other surface defects such as waviness, scratches, or dents. By incorporating multiple cameras and laser line projectors from different angles, a comprehensive inspection of the steel coil's surface can be achieved. Overall, the utilization of optical sensors for inspecting steel coil flatness offers a swift, precise, and non-contact method. By identifying and addressing any flatness issues early in the production process, manufacturers can guarantee the delivery of top-quality steel products to their customers.
