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:Why aren't bullets made of steel?
As others have mentioned, steel lacks the ductility to conform to rifling and seal the bore. Cannon projectiles, which usually are made of steel, overcome this problem by using one or more driving bands of softer metal, usually brass or bronze, but sometimes even plastic, on the circumference of the projectile, usually close to the base. The body of the projectile rides on the lands, while the driving band fills the grooves, seals the bore and imparts the stabilizing spin to the projectile.
Q:Steel plugs in the winter?
Personally, okorder.com They are spot on for sizing, they do customs, and amazing quality like i have never seen before and I have been through a lot of plugs. Hope this helps :)
Q:Bike Frame-Aluminum vs Steel?
I wouldn't worry about strength so much. I have never heard of anyone breaking a aluminum frame. One difference to consider is stiffness. A aluminum frame bike seems to be more stiff of a ride than steel ( talking chrome molly), stiffness has good and bad points depending on how you plan to ride.
Q:what is 440c stainless steel means?
It is the alloy number given by the American Iron and Steel Institute, or AISI. This is the trade organization of the U.S. steel industry, one of the oldest such organizations. 440C is also known under the UNS system as S44004 440C is a high carbon, plain chromium stainless steel. Or more specifically: 18% Cr, ~1.1% C, ~1.0% Mo, Si, and Mn 440c is mostly used in cutlery, bearings, and valve parts; because it has the best strength and hardness after basic heat treatment of any stainless steel. Relatively poor properties in other areas make it less suitable for other types of items. for example 440c becomes very brittle in sub zero temperatures. 410 is similar to 440, but it is a cheaper milder steel with less chromium and carbon, so it is less brittle, more easily worked and machined, but lacks final strength and hardness. it is often used in cheap stainless fasteners and bushings.
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's the difference between stainless steel and surgical steel...?
Stainless steel is steel with lots of carbon in it. The amount of carbon gives it a so called grade. Marine grade, surgical grade etc.
Q:Steel or wood?? About the resistivity?
Wood, and it depends on the elements making up the 'conductor' .. and how 'mobile' electrons are in the material .. To a first approximation (non-exotic materials), if the elements form molecules where electrons are 'weakly bound', then that material will conduct electricity. The 'weaker' the binding (and the more electrons), the better the conductor .. (it is, of course, much more complicated than that .. see link)
Q:what is stainless steel?
Corosion Resistant steel..... It does corrode... just at a slower rate then normal steel.
Q:Cold steel katana?
Can see this one is gong to cause a lot of controversy, price, country of origin, stuff like that might help you form an opinion on the particular sword
Q:Is Steel a Pure Substance or a Mixture?
Steel is mostly iron. However, it is an alloy or solid solution, or mixture of iron and other metals or sometimes carbon. All steel is a mixture. there are many varieties.
