Galvanized steel coil

 

Introduction:

The galvanized steel coil is made by cold rolled steel sheet, then trough chromated. unoiled, various spangles, hot dipped. The surface is coated by zinc or aluzinc. it is widely used as the raw materials of building. we have exported to midle east, africa, south america, ukraine for the good quality and best credit.

Q:what metals are more dense than steel?
Look at a periodic table of the elements. The atomic weights are a guide to density. Tungsten is denser than tungsten carbide because it doesn't contain carbon. Also denser than steel are gold, lead, platinum, and a number of other metals. Steel is iron combined with lighter elements, so iron is denser than steel.
Q:For those metal experts out there, steel or stainless steel.?
Whilst doing a welding course a few years ago the teacher said stainless steel was not its proper name,it is called Heat and Corossion resistant steel,it come in different grades related to its corossion resistance,priced accordingly.Must be welded properly without introduction of carbon to the weld (carbon pickup) or the weld might not be there next time you look dependant on environment.Generally harder to form than mild steel (low carbon steel) so it will tend to be stronger than lcs for the same cross section.steve
Q:Steel Making Process?
From what I understand of it, US steel is better as the steel is more recycled than Canadian, so a lot of that oxygen / CO2 has already taken place compared to working from ore. The second reason US steel is environmentally ahead of Canadian is that US tends to use Electric Arc, while Canadian uses Basic Oxygen, Basic Oxygen uses more energy than electric arc, and I think it also uses more oxygen, but I would suspect that oxygen that it uses is 'waste oxygen' and not converted into Co2 because the Co2 process is limited by the carbon, and steel only has so much carbon.
Q:hard ionized vs stainless steel cookware?
A good quality stainless steel cookware set is a necessity- it is virtually indestructible and you can use the harshest of scrubbers to clean it. You will need a basic set that has a 8 and 12 fry pan/omelet pan, a large pot that holds a minimum of 4 quarts, and 2 sauce pots at 1 quart and 2 1/2 quart sizes. I have several pieces of hard anodized cookware too- they do a wonderful job but food will still stick. A must is at least one Green Pan- preferably a 10-12 fry pan. They are truly non-stick, clean up is a breeze and making foods like fried eggs is infinitely easier when they slide out of the pan without breaking. They do not have the same issues that plague teflon pans- scrapes and shedding that you are ultimately consuming. You can easily find them online and at your area Target store.
Q:Reloading and shooting steel.?
You can't reload steel cases. I don't really know, but you just can't. If a mild steel case is harder than the chamber and bolt of your firearm, you should have got a better firearm.
Q:what is difference between high carbon steel blade for katana swords?
1060 Carbon Steel
Q:how do I convert my house to be built to a steel stud home?
Steel is going to be a whole different world. You will need to go back to square one and get house plans that are drawn for structural steel. First thing you need to do is find a builder that knows how to build with steel and get an idea of the price.

Q:Can you give me the general working and description of a steel cooling bed?
Another type of cooling bed is used for square stock. It consists of several beams with angles cut upward from the bottom. The beams move in alternating fashion so that the square beam is lifted and sat into the next 'tooth'. The angle is cut so that the beam rotates as it is set down. This keeps the stock straight while it cools.
Q:what is the chemical composition of the steel material to be used for steel tube ferules?
I don't know your application, but here is some advice. Case hard provides a hard shell around soft steel, depending on the bake, the case is usually .002-.008 thick. (thousands of an inch) Heat treated steel or tool steel is hard all the way thru. Case hardening, provides toughness with flexibility, however, once it's compromised, the part is scrap. Hardend tool steel is extreemly hard throughout and the harder it is, the more brittle it becomes. The application of the part will help you to determine the material needed. For instance; Plastic injection molds are very hard so the hot plastic wont erode them over years of use. Punch Press dies aren't as hard but are tougher to withstand the shock. Machine bolts are case hardened so they can last, but soft enough to allow some stretching during tightening. Either way, the time in mfg will be about the same. Most tool steels today cut like cheese, but take time to be heat treated. Tool steel will cost a bit more than low carbon steel. Low carbon steel is as machinable, and cheaper, but, again, the baking period is as long or longer than tool steel. There are a lot of materials on the market today that maintain the durability of heatreated steel without having to go thru that process. 4140, ( or chrome/moly) comes to mind. There are also some 400 series stainless that work as well, and others. You need to determine strength, flexibility, ease of mfg, cost and repairability when considering which steel to use.
