Description

Pre-Painted Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized steel sheets.

The Pre Painted Steel Coil can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.

The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.

The base metals for Pre Painted Steel Coil consist of cold rolled, HDG electro-galvanized and hot-dip alu-zinc coated steel. The finish coats of Pre Painted Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

Q:how to clean old steel coins?
if you collect coins, you need to learn that they must never be cleaned. cleaning, while it might make them look pretty, ruins their value as a collectable. ask your coin dealer.
Q:stainless steel properties??
Stainless steel is a generic term for a whole range (there are more than 60 types) of Fe-Cr alloys. They all contain some amount of C and some alloys include a good number of other alloying elements. In almost all cases, the materials have corrosion resistance due the Cr atoms that are in solid solution with the Fe matrix. Under corrosive conditions, the Cr forms a thin tight coherent layer of Cr-oxide. This Cr oxide coating prevents further corrosion so long as it is not chemically or physically removed. If the SS has been subject to mechanical abrasion, the corrosion resistance can sometimes be restored by a light exposure to nitric acid which passivates the surface, restoring the Cr-oxide layer. The carbon content is an important factor in corrosion preformance but so is the heat treatment. Under the wrong conditions and in different environments, all SSs can rust. One of the most common corrosion problems is sensitization which occurs in the heat affect zone (HAZ) around welds. If the C content is high enough and the heat is high enough, the Cr atoms in solid solution form Cr-carbides and are no longer available to form a protective Cr-oxide. The corrosion resistance can be restored by appropriate heat treatment.
Q:Why was there molten steel at Ground Zero?
that's just it: there wasn't very much molten steel for the very reason you point out. Jet fuel burns at 800° to 1500°F. This is not hot enough to melt structural steel. However, engineers say that for the World Trade Center towers to collapse, their steel frames didn't need to melt, they just had to lose some of their structural strength. Steel will lose about half its strength at 1,200 degrees F. The steel will also become distorted when heat is not a uniform temperature. after the collapse, a LOT of folks took a look at the remains. the result was the conclusion that the fire caused the central core of the building to weaken. When the floors collapsed one on top of the other, the weight was too much for the weaked core to bear, causing the result we are all familiar with. hope this helps
Q:Handgun steel question...?
The first answer was correct. The type of steel used in most blued handguns is the highest. After that I prefer stainless. Then the Scandium framed pistols.
Q:Steel shafted woods vs Graphite woods?
I'd be very surprised if there are any tour players still using steel shafts on their woods (I did actually see Tiger with a steel shaft on a driver during a clinic in 2002). Top end graphite shafts have gotten so much better there's just no reason for pros not to use them anymore. That being said, I use a 45 True Temper stiff steel shaft in my driver (Cobra X-speed, 9.5*). Graphite is longer than steel, but the distance I've lost is minimal (maybe 10 yards and I still put it out there 250+ consistently). The extra weight has actually helped me stay in control which has improved my overall driving considerably, and the very low torque in a steel shaft has paid off huge in accuracy. You're paying minimum $60 (or more) for a graphite shaft with a similar torque rating to any steel shaft. I hit easily twice as many fairways since the switch. I've even switched out my other fairway woods too, the feel and control are so much nicer. I've considered going with a 46 on the driver to try to regain some of the distance, and at $7 per shaft I can actually just go do that whenever I want. Don't get me wrong, if I were playing for money or flirting with par I'd invest in good quality graphite stuff no question, but it doesn't make sense to me right now. I'd recommend to anyone looking for more consistency out of their woods to take $20 to your golf shop and try it out. It's a lot cheaper than the alternatives.
Q:how do you rate the hardness of steel?
There's an instrument called a hardness tester. It has a stylus which is pressed into the surface of a sample of steel with a calibrated amount of force. The distance it penetrates tells you how hard the steel is. (This is sometimes called 'indentation hardness'). The most common scale is the Rockwell Scale. Actually it gets a little complicated because there are several scales, one for tungsten carbide (the hardest man-made material), one for aluminum and brass and soft steels, and one for hardened steels. Another scale for indentation hardness is the Brinell scale. It's a little less complicated, with one scale to measure the hardness of wood, plastic, etc. as well as steel.
Q:Why is stainless steel rust proof?
Rust Proof Metal
Q:Steel Research?
Your okorder.com (they make steel deck and steel joists) There are thousands of other items routinely produced from steel, including rebar, and all the metal in cars, airplanes, and about a million other things.
Q:how can you temper steel?
You can't temper all steels. Generally the material must be a high-carbon or tool steel. Different alloys temper differently, and tempering is usually done to get a specific set of characteristics, so you must know what you are working with and use the right methods and temperature. If you do it wrong, the material may be hard but too brittle for the purpose or have other issues. It can be simple, such as heating to a dull red, carbonizing the surface (use an acetylene rich flame until it blackens the surface) and oil quenching. Do that to a piece of tool steel (like a screwdriver) and it will case (surface) harden it to the point you can't scratch it with a file. Tempering changes the way the molecular structure in the metal is linked and oriented.
Q:Chemical difference between steel & stainless steel?
the reagent of choice is toluene-3,4-dithiol.
