Product Description:

SPCE COLD ROLLED STEEL

Brief Introduction

Cold Rolled Steel is steel that has been worked below itsrecrystallization temperature by passing it between a pair of rollers.Recrystallization temperature is the temperature at which grains in the latticestructure of the metal have been rearranged, leaving it free of strain anddeformations. Cold Rolled Steel is pre-treated before being cold rolled with aprocess known as pickling, which uses strong acids to remove scale and otherimpurities. The Cold Rolled Steel is then passed through rollers to reduce itsthickness. Most cold rolling takes place in multiple passes and as the size ofthe Cold Rolled Steel is further reduced, its strength and hardness bothincrease, but its ductility decreases. After cold rolling, heating the metal upin a process known as annealing can restore some of its ductility. The finalCold Rolled Steel may be manufactured in the form of sheets, strips, bars, orother forms.

Application

It’s widely used in outdoor and interior decoration, furnishingmanufacturing, home appliance, automobile etc.

Q:Is m390 steel aka 20cv steel a tool steel?
Not all tool steels work well in knife blades, but some of them are very popular. D2, M2, M4 and many others.
Q:How hot does steel?
Type your query into Yahoo! Search or other search engines to get the answer: It depends, since steel usually has different metals added for various properties (strength, corrosive resistance, etc.)
Q:Are a guys balls really made out of steel?
Yes, sometimes the steel is hot, and sometimes it is cold. The important thing is that both of you know what you are talking about and focus to the specific thing. If the steel ball is hot all the times, then it is the time to pack your things and to consider to find another balls. Conclusion: your guys balls are not made of *real* steels. Hope it is helpful. PS. If you lick steels, it has metallic taste.
Q:Permanently expanding steel?
You can calculate the maximum reversible strain, for elastic loading as follows: You need to look up the yield strength (for that particular type of steel). Divide this yield strength by the elastic modulus of steel (also called Young's modulus). That gives you the strain at the onset of yielding, the maximum you can strain the steel fibers before crossing the point of no return. If you are interested in the strain until failure, you need to take tensile test measurements. Seldom do people document an equation to model the non-elastic portion of the stress-strain curve of the specimen, because seldom do we design systems to operate with materials which yield. We want systems which only deform reversibly and elastically. This means you need to perform an experiment to find what you are actually desiring to know.
Q:Why nickel makes stainless steel non-magnetic when nickel itself is ferromagnetic?
All stainless steel is non magnetic.
Q:Steel Price .........!!?
Hot Rolled Steel Coil – $562 per metric tonne Hot Rolled Steel Plate - $748 per metric tonne Cold Rolled Steel Coil - $654 per metric tonne Steel Wire Rod - $507 per metric tonne Medium Steel sections - $751 per metric tonne
Q:Why are some steel companies more successful than others?
Steel is a global commodity. There is some variety in product (flat rolled, tubing, etc), but basically the same product worldwide. Cost to the customer includes shipping of a very heavy product. Inputs are also heavy and costly to ship. Inputs: - Coal - Iron Ore. Some firms have the ability to recycle old steel, a competitive advantage. - Energy (very energy intensive industry) - Labor - Machinery. A new blast furnace is more efficient than 50 years old. So the most profitable steel firms have some of these characteristics: - Proximity to raw materials - Proximity to customers - Access to cheaper means of transportation; rail and sea - Newer machinery - Cheaper labor force - Reasonable cost for electricity and fuel for furnaces
Q:Strength of aluminum/steel i-beams?
Yield strength of aluminum vs steel beams may be a little bit higher depending on the alloy. However due to the widespread use of steel I-beams you should be able to get them for a much better price. Are you sure the existing beam is not stainless steel rather than aluminum this seems a lot more likely.
Q:What is the difference between steel and iron?
Iron and Steel Manufacture, technology related to the production of iron and its alloys, particularly those containing a small percentage of carbon. The differences between the various types of iron and steel are sometimes confusing because of the nomenclature used. Steel in general is an alloy of iron and carbon, often with an admixture of other elements. Some alloys that are commercially called irons contain more carbon than commercial steels. Open-hearth iron and wrought iron contain only a few hundredths of 1 percent of carbon. Steels of various types contain from 0.04 percent to 2.25 percent of carbon. Cast iron, malleable cast iron, and pig iron contain amounts of carbon varying from 2 to 4 percent. A special form of malleable iron, containing virtually no carbon, is known as white-heart malleable iron. A special group of iron alloys, known as ferroalloys, is used in the manufacture of iron and steel alloys; they contain from 20 to 80 percent of an alloying element, such as manganese, silicon, or chromium.
Q:Is Damascus Steel Fake?
Well, it depends on what you call fake. Modern Damascus steel is perhaps similar, but it is not what people would call Damascus steel in 1500. It is made to look similar, but structurally it is different. For the most part the specific way of making Damascus steel is lost to history.
