 High Quality Cold Rolled Steel Sheet in Coil

PRODUCT DESCRIPTION

Brief Introduction
Cold rolled steel coil is steel that has been worked below its recrystallization temperature by passing it between a pair of rollers. Recrystallization temperature is the temperature at which grains in the lattice structure of the metal have been rearranged, leaving it free of strain and deformations. Cold rolled steel coil is pre-treated before being cold rolled with a process known as pickling, which uses strong acids to remove scale and other impurities. The cold rolled steel coil is then passed through rollers to reduce its thickness. Most cold rolling takes place in multiple passes and as the size of the cold rolled steel coil is further reduced, its strength and hardness both increase, but its ductility decreases. After cold rolling, heating the metal up in a process known as annealing can restore some of its ductility. The final cold rolled steel coil may be manufactured in the form of sheets, strips, bars, or other forms.

Q:How much pressure can concrete and steel take?
Your question is not specific,there are many types of Concrete according to ratio and many types of steel but if want general answer,Concrete is good for compression and for 1:2:4 Cement-Sand-Gravel Ratio up to 4000 psi but very weak in tension where as tor steel is good for tension and is about 70000-80000 psi .
Q:stainless steel wall ties?
wall ties are used to tie brick coursing to the back up wall...stainless steel will simply last longer than the others but you will pay dearly for them...
Q:Anyone seen Man Of Steel?
I know nothing about Superman nor have I watched the other films or read the comics. Man Of Steel was a CGI-fest, maybe a little bit too much, though it is Zack Synder's style. I actually fell asleep for most of the movie, seeing only the first 30 minutes and last 45 minutes? So that might be a good indication or it could just be me. There were loads of action scenes but overall, the movie wasn't that impressionable to me. The storyline was quite standard and had nothing outstanding, not even humour. Lois Lane and Superman barely had much screen time together to establish any chemistry. The other characters were pretty flat as well. I did like the dark psychological themes of Superman's struggles and coming to terms with his abilities though.
Q:how strong is 440 stainless steel?
For throwing knives, 440 isn’t necessarily a bad choice. Does it list whether it is 440c or 440b? That matters somewhat. The advantages of 440 Stainless is that it’s relatively hard (for a stainless), it resists rust significantly, and it’s not so hard that it would shatter or break. On the down side 440 is notorious for not taking or holding an edge, but for a throwing knife, that’s probably not much of an issue. If you’re looking for something to train with, you’re fine here. It’s plenty of steel enough to stick in wood or other targets. Odds are it won't bend if you slam it into some wood. If it lands on concrete, eh, it's going to scratch and all that jazz, and it might hurt the tip if it hits first, but as has been said, you can use a file or grinder to get the tip back.
Q:What is better carbon steel or stainless steel for a knife?
carbon steel is my choice. googlecarbon steel vs stainless steel knives for more info. If you buy stainless make sure it is an alloy that will hold an edge..many a shiny knife is just a dull dud. Carbon blades don't rust unless they are left laying in the wet. I was having this conversation with a Friend once. So I took his knife and struck his knifes edge against mine with a light blow.. His had a 1/16 dent in it, mine not even a mark on it. I assume this is not a kitchen knife.
Q:AK47 firing through steel?
It can't go through inches. It can go through up to 1/4 of an inch of plate steel but not much more. An M-16 can go through it as well and has less powder behind it but the 7.62X39 is a fat round and it takes a little more to get it through.
Q:Is this guitar steel string or nylon?
if you can get a good picture of the bridge i can tell for sure i thing steel
Q:How much is obselete steel worth when sold as scrap?
Right now, steel is worth $150/ton. Who purchase it? Well, not every scrap yard handle steel, you have to call them up, or look at the company name that has the word steel or iron. But price can vary from each scrap yard. Try to call around. As for someone to pick it up, the scrap yard will mostly charge you a trucking fee and then the price for steel would be lower. But here is another bad thing if you have it pick up. I know some scrap yard are bad...reall bad..they will skim off some weight...a 1k lbs to 2k lbs. Wish you good luck!
Q:what are the characteristics of iron / steel?
Technically, this is known as ductility. a material which can be permanently bent and stretched is said to be ductile. Pure iron, when it lacks carbon and impurities like sulfur and phosphorus, is relatively soft, ductile, and weak. It's about as soft as brass. It can be stretched to about 50% of it's original length before it breaks. The amount a sample can be stretched without breaking is known as elongation. The key to steel is the addition of about 2 parts per thousand of carbon, or around 0.2%. This alters the crystal structure and makes steel much harder, stronger, and tougher, though it also becomes somewhat less ductile. Mild steel, with a low carbon content, has an elongation of around 30% Adding more carbon makes the steel yet stronger, but further reduces the elongation. Adding more than 2-3% carbon produces what is known as Cast Iron. Cast iron is brittle. It has virtually no ductility. It's pretty cheap to produce though.
Q:Are there steel bullets?
They will both knock it over, but it depends on how the bullets hit the block. If the steel bullet hits the block at any kind of an angle, it will knock it over because it will enter the block cross grain. If it hits it straight on, it will not have as much resistance as it goes with the grain of the wood. The rubber bullet will have more resistance because it does not pierce the block. The force from the rubber bullet would be the same no matter what angle it comes from.
