Product Description:

Cold Rolled Steel Coils-DC03 with  High Quality

Brief Introduction

Cold Rolled Steel is steel thathas been worked below its recrystallization temperature by passing it between apair of rollers. Recrystallization temperature is the temperature at whichgrains in the lattice structure of the metal have been rearranged, leaving it freeof strain and deformations. Cold Rolled Steel is pre-treated before being coldrolled with a process known as pickling, which uses strong acids to removescale and other impurities. The Cold Rolled Steel is then passed throughrollers to reduce its thickness. Most cold rolling takes place in multiplepasses and as the size of the Cold Rolled Steel is further reduced, itsstrength and hardness both increase, but its ductility decreases. After coldrolling, heating the metal up in a process known as annealing can restore someof its ductility. The final Cold Rolled Steel may be manufactured in the formof sheets, strips, bars, or other forms.

Q:Shaft stiffness in steel irons???
If i understand you correctly, i think you misunderstand shafts. Steel shafts vs. graphite shafts these days is more of a competition of weights, not flexibility. Both steel and Graphite have different flex profiles available from Ladies (L) to super stiff (X). Graphite may feel a little more whippy than steel because of the lighter weight. Shafts will vary by company as well. Stiff from True temper may not be as stiff as one from Aldila, or vice verse. You can also make a shaft play stiffer or more flexible by where you cut the length. This is called tipping. Take more from the bottom and it will be stiffer, more from the grip end and it will play more flexible.
Q:how does steel become stainless?
a little clarification. steel doesn't become stainless. There are many different types of steel, which is an alloy of iron and other element. The other elements determine things like hardness, corrosion resistance, etc. One element is chromium, which when added in the correct proportions, forms stainless steel. PS, there are many many different stainless steels, with different proportions.
Q:Steel Building Kits...!!?
Of course yes! Steel building kit is design specific corresponding to the type of steel building required to be constructed or erected. The steel building kit consists of all the necessities needed by the purchaser or the investor. As steel buildings are prefabricated or pre-engineered they are manufactured in factories in various sections and parts which are to be brought to the construction site to be assembled. So in any case they are beneficial :)
Q:why use steel-reinforced concrete?
Steel is strong in both tension and compression. No Steel is strong in tension. Under compression it will bend. Example. Take a steel cable. stretch it (Ok you cant) Now compress it. it bends. Bridges generally need support from below. So you need something thats strong under compression. IE concrete. However concrete can fail if it gets a tension - so pre-tensioned steel rods are cast into it to take any such tension (stretching or bending) forces.
Q:Does steel make its own static electricity?
If you sprinkle iron filings near a bar magnet (on paper, etc.) the filings will try to line up with the magnetic field (because iron atoms behave like tiny magnets). Bringing the compass near steel (mainly iron with a little carbon) will cause the iron to try to align with the magnet of the compass needle, however, because the needle is free to swing it also aligns with the magnetic field set up between the needle and steel. Any static electricity would have nil effect on the magnetic field.
Q:buying Stainless Steel refrigerator?
it is indeed in style.. but they're very hard to keep clean. take it from me. i have one. and if you even toush it with your finger. there's a smudge or mark. you have to constantly keep cleaning it. but it's no different that having a regular new refrigerator. they're just more stylish. but overall you should get the stainless steal one. just keep up with it. lol. hope it helped.
Q:difference between metal and steel?
well, steel is a type of metal. It's sort of like asking the difference between a bug and an ant, an ant is a bug, but not every bug is an ant. Likewise, steel is metal, but not all metal is steel. Gold is metal, Silver is metal, Iron is metal, Steel is metal.
Q:Where can I get a steel taper kit?
All okorder.com/... This is the cheapest stainless steel taper kit i could fine. You can also use titanium and glass, but never use acrylic tapers because they're cheap, toxic and will give your ears that really nasty smell as you get into bigger gauges. I hoped i helped.
Q:what steel anodizes well?
Steel doesn't anodize in the sense that aluminum and some other metals do. However, it can be heat-colored. The trick is to clean the surface first (it must be oxide free), then heat gently until the colors appear. These are called temper colors in steel. They are due to a thin adherent layer of oxide that forms and thickens as temperature is increased. They are quite temperature dependent. As the steel is heated, the first color to appear is pale yellow. This will progress through darker yellows, browns, purples, and blues as the temperature rises. Above blue, the oxide becomes the gray/black color you are apparently getting - this is the result of heating too fast and too hot. See the chart at the site below for colors in plain carbon steel. Note that the temperatures are pretty low - It all starts around 400 F and if you go above 600 F the show's all over.
Q:What brand steel tapes are of good quality?
Personal feeling is also good for the Great Wall Seiko tape, upstairs several estimates are the production of steel tape manufacturers, of course, that their goods well. Our unit now buy all the Great Wall Seiko goods, said the tape is good, not because it is so durable
