Product Description


Brief Introduction
Cold Rolled Steel 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 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 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 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:are Train Tracks made of the Strongest Steel?
No, train tracks are not made of the strongest steel. Actually, I believe they are made from a rather mild steel, maybe a high-carbon steel in the curves, but no means is this top of the line. Probably the best all around high strength steel, if you count hardness, tensile strength, shear, and yield is Eglin steel. It has a yield of about 245,000 psi an ultimate strength of around 293,000 psi a harness of 45.6 and an impact of about 75 joules. It's cheaper than exotic alloys, you can build aircraft with the stuff because weight isn't an issue and it's plenty strong enough. Its also very strong even in extreme temperatures. The material has a wide range of other applications, from missile parts and tank bodies to machine parts.
Q:How is steel manufactured?
Abed is off on some of the details... Steel is, by definition, Fe-C. There are thousands of different steel alloys and I am not aware of a single one that is simpkly Fe-Ag. There are different processes but the chemistry is basically the same, converting the iron compounds we dig out of the ground into metallic iron. Iron is typically found as iron oxides or iron sulfides (not with a lot of carbon). We add carbon so the carbon takes the oxygen from the Fe atoms making Fe + CO/CO2. Research iron smelting, iron ore, reduction of iron oxide, these types of things. You will find plenty of information because this is one of the most important industrial processes humans have. Good luck
Q:What does buns of steel mean in this sentence?
Means you will have a nice booty, but the true question is... What does Buns of Steel mean by several times and SOON? Good luck.
Q:Is carbon steel a type of alloy?
Carbon steel, or plain-carbon steel, is a metal alloy. It is a combination of two elements, iron and carbon. Depending upon the amount of presence of carbon in the alloy, Carbon steel can be classified into 4 different categories- Low Carbon Steel Medium Carbon Steel High Carbon Steel Very High Carbon Steel
Q:What material is strongest? Human bone, steel, or concrete?
I guess I would ask you to define strong then? For example: make a bed and line it with steel, then lie down in it and have someone poor concrete on you. Let it dry overnight and then try and get out. What will break first? Could be anyone of these. If you had a watch made out of bone or concrete and it fell off, it too would break. There you have it amigo, define strong!
Q:Lead vs steel chokes?
You should not have done this. It not a matter of shooting fine - it's a question of getting the correct distance and shot pattern SAFELY. Lead only chokes squeeze the lead shot a considerable bit. Lead is compressive and soft - it takes more squeeze to get the correct patterns from a shotgun. Steel only chokes do not squeeze as much as the lead version because the steel is very had and does not compress well. When you accidentally shoot lead through a steel chock the pattern will be weird. But, it usually is not an unsafe condition. However, steel through a lead choke will cause unsafe pressure at the choke and can explode. You end up with a bugs bunny/road runner cartoon looking shotgun! Most gun shops all over the USA are decorated with these blown up shotguns from people doing exactly what you did. Unless you want to add yours to the other dead gun collection in some shop - I recommend you take your shotgun and all your chokes into a gun smith and have him look it all over. See if anything is out of tolerance. Guns are not fool proof. If you do not follow the instructions and operate them safely they will blow up and tear a piece of your body off. Just ask any ER doctor or long time shooter.
Q:Hiking with steel toe-capped boots?
Steel toed boots are very heavy compared to hiking boots, after a long hike (especially in rough terrain) the extra weight is gonna tire you out. Steel toes are made for things like construction, or doing a task where extra protection of the toe is needed. So it's not ideal, but whatever floats your boat man (better than wearing tennis shoes). I personally have Converse composite toed boots from my airsofting days and since im too cheap to buy dedicated hike boots, I use it for hiking. Its supposedly made for military use and is much lighter than steel toe. But WAIT!!! lets say you dont have a gun or knife and you run into a pissed off Sasquatch, a steel toe boot too the nutz would do well in puttin the hurt on the dude.
Q:Can I put nylon strings on my steel string acoustic guitar?

Q:Judge Quality of Steel?
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:Should I keep my steel cents as an investment?
The steel in steel cents is the same as the steel in soup cans you throw out all the time. There is no sense in holding steel cents for their value as scrap. There are way too many steel cents around for them to ever have much numismatic value.
