Q: Can cold rolled galvanized steel coils be acid washed after oxidation?: Hot rolling is made of slabs (mainly continuous billets) as raw materials. After heating, strips are made from roughing mills and finishing mills. From the last finishing mill stand out of the hot strip laminar cooling through to the set temperature, the coiling machine rolled strip steel roll cooled, according to the different needs of users with different finishing line (flat, straightening, transverse or longitudinal, inspection, weighing, packing and marking etc.) processing and become steel, flat steel product volume and slitting.

Q: Is steel harder than iron or is iron harder than steel?Please explain... and help!Thanks: steel is harder than iron Iron is a chemical element. It is a strong, hard, heavy gray metal. It is found in meteorites. Iron is also found combined in many mineral compounds in the earth's crust. Iron rusts easily and can be magnetized and is strongly attracted to magnets. It is used to make many things such as gates and railings. Iron is also used to make steel, an even harder and tougher metal compound. Steel is formed by treating molten (melted) iron with intense heat and mixing it (alloying) with carbon. Steel is used to make machines, cars, tools, knives, and many other things.

Q: How are steel coils inspected for dimensional accuracy after processing?: Steel coils are inspected for dimensional accuracy after processing using various techniques such as laser scanning, ultrasonic testing, and manual measurements. These methods ensure that the coils meet the required specifications and tolerances, guaranteeing their quality and suitability for further use.

Q: Is condensation on steel caused from water being pulled out or is the condensation formed from the air around the steel object?: Steel contains no water; any water that you see is condensed out of the air.

Q: My musical saw has, despite my best efforts, got little patches of rust on it. How Do I go about removing the rust without spending too much on rust-removal products and without affecting the properties of the steel?: Steel wool and a bit of WD 40. Steel wool will remove the rust and the WD 40 will protect it in the future.

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: 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: Does a magnet stick to galvinied steel?: yes it does. The steel below the galvanized coating still has a relative high carbon content and magnets stick to it. Magnets do not stick to stainless steel very well though. There is a weak attraction there. If I recall correctly this is due to the relatively low carbon content and the higher content of chromium.

Q: How are steel coils tested for strength?: Steel coils are tested for strength through a process called tensile testing. In this test, a small sample of the steel coil is pulled until it breaks, allowing engineers to measure the maximum force the coil can withstand before failing. This helps determine the overall strength and quality of the steel coil.

Q: I am about to do a welding project and we are instructed to only use mild steel. I want to use found objects like coins, spoons, bottle caps, screws, and other small fasteners. Are these mild steel? What other objects can I use that are mild steel?: Mild steel is what your friends get when they see your mom's cleavage.
