HOT ROLLED STEEL COIL

Q:What are the common methods of joining steel coils together?: The common methods of joining steel coils together include welding, mechanical fastening (such as using bolts or screws), and adhesive bonding.

Q:I mean about if I had a piece of metal, how can i decide that's iron or steel?Sorry for bad English.: There are literally hundreds and hundreds of different commercial steel alloys and a good number of iron alloys so... it depends. Technically, steel is any alloy that is mostly Fe with some amount of carbon. Even if you have access to the necessary lab equipment, CTE (coef of thermal expansion) and specific heat are not very straight forward tests. There are, of course, chemical analysis instruments for measuring C content in steels so, if you really need to know, you can spend money at commercial lab that does these tests. One quick test to judge C content... touch the metal to a grinding wheel, higher C content produces more sparks. To calibrate the way this looks, compare the sparks from a drill bit (usually 1090 steel so 0.9 wt% C) to a steel nail (low C steel). Unfortunately, the difference in sparking between steels with pretty low C content and a piece of iron will not be very dramatic. Of course, iron might mean Cast Iron and, again, there are a good number of commercial cast iron alloys and there are 4 basic types of cast iron alloys and they contain high amounts of C.

Q:What are the different types of steel coil storage methods?: There are several types of steel coil storage methods, including stacking coils directly on the floor, using racks or shelves, utilizing coil cradles, employing coil saddles, and implementing coil cars or trucks for transportation and storage.

Q:How many pounds can steel lift?: I think that you failed to put up a meaningful question. I suggest that you try again and seek help.

Q:Don't ask me why, but I took my stainless steel ring and I heated it up with my gas stove. I stuck it in there til the metal turned red, and the flame which is normally blue turned orange for some reason when the metal turned red. Anyway, afterwards i cooled it off in water and now it's all discolored and it feels different. It's weighs less and it doesn't feel the same. Plus, it's ugly cause it's all black and blue. What happened? Someone help: Stainless steel has a rating. I don't know what your ring's stainless steel rating is. If you know, you can look it up. The rating will tell you how much steel vs other metal it has (usually Cr and Ni). But usually when you heat the stainless steel to extreme temperature it will discolor due to oxidation. What is worse is that you cooled it off in water (I assumed that you did it while it was still hot). By rapid cooling, you have changed the physical structure of the steel itself. It will change the hardness of the steel. That is why it feels different. Look up on annealing, normalizing, quenching and tempering under heat treatment for steel.

Q:so i've started learning to play guitar in the past few weeks, and i'm using my sister's old guitar which isn't in very good condition, so i'm planning on buying a new one, but which would be better to buy, nylon string or steel string?: It rather relies upon on what type of music you're enjoying, nylon string guitars have a mellow, softer tone than steel strings, the feel of the nylon strings (a minimum of to me) are reliable, in my opinion, i might ought to declare nylon is extra suitable, large for finger choosing and a effective tone. once you're searching for a guitar, you are able to flow out to a close-by guitar save, and attempt the two out for your self, in straight forward terms then will you comprehend for specific.

Q:I am wondering if i can use my western guitar as a kind of steel-guitar, read something about it on Wikipedia.: Musical style speaks volumes while it includes this concern. people who % severe quantity would be unhappy with unamplified nylon string guitars. From my attitude, the common distinction between metallic and nylon is this: metallic strings ring and nylon strings resonate. the quantity produced by employing metallic is frequently plenty greater suitable than nylon yet, to my way of thinking, the sound resonance produced by employing the wood of your guitar is largely masked by employing metallic strings. in case you have a decently made guitar (frequently, around 1000 money and up), the sound interaction between the wood and the strings in a nylon guitar is magical around the completed frequency selection. With a metallic string guitar, the sound produced by employing the vibrating string overpowers the wood resonance in any respect yet low frequencies. in my view, i will take a nylon string guitar any day for the sensitivity gained from the interaction between wood and vibrating string.

Q:Maybe it is obvious. But i have thought alot about it.I thought steel at a cool temperature was unbreakable. I am not one for science or physics or engineering (i am a political science major). But i don't understand why the planes that struck the world trade center on 9-11 didn't just dent the side and fall,How did the place break the steel? Was it the velocity? Is steel easily broken?I realized that i wasn't taught how the planes broke the steel, and that no one ever asked. I searched the web and i couldn't find the answer or even anyone who had asked the question before.(i don't care about conspiracy theories, i just want scientific facts): I saw a one-hour program about this on PBS a couple of years ago. The buildings were constructed with the concrete-clad steel supporting columns at the center of the buildings, with a relatively thin lattice of steel struts along the outer wall. When the planes hit, they sheered through the thin steel struts easily by sheer momentum, while, at the same time, the thin steel stripped off the wings. The bodies of the planes got as far as the supporting columns in the center of the buildings, but were stopped there. The heaviest, densest pieces, the engines, went completely through the buildings and popped out the other side. It's important to understand that even light materials can cut through metal, if the light material is going fast enough. I saw this first hand, when I was in the Navy and stationed on board ship. We had a helicopter crash on our flight deck during heavy weather. The blades were made of light, carbon-composite material, but they were going so fast that they cut through the aluminum deck. I still have photos of that damage.

Q:I'm missing the arguement, and I've seen another question like this... but the steel toe issue has 2 scenario's right?... Let me label them out, the 2nd is the one that no one talks about?Note to anyone - how are your catapillar boots, your wolverines, and then your cheap walmart/sears brands?1. Steel toe on, toes get cut off because of something falling on them. OUCH!.. Reattach perhaps?2. This one is what I question. No steel toe, large object falls on toes. SMASH... Pudding in your shoes.Wouldn't it be safer to say you'de be better off with a steel toe?: Go to Discovery channel and look up Mythbusters episode on steel toed boots. It will surprise you what they can take, even with dropped items. They could get some damage, but never a severance.

Q:What is the role of steel coils in the production of pipes and tubes?: Steel coils are essential in the production of pipes and tubes as they serve as the primary raw material. These coils are unwound and fed into a pipe or tube mill where they are shaped, welded, and formed into the desired dimensions. The high strength and durability of steel make it an ideal choice for manufacturing pipes and tubes, ensuring their structural integrity and ability to withstand various applications and environments.
