Product Description:

1.Structure of Hot-Dip Galvanized Steel Sheets in Coils JIS Description:

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering.

Q:What is the best steel to use for making a knife?
O-1 is an excellent steel. If you've never made a knife before find an old file and use it. My first knives weren't that good, it took a little practice to get the geometry right so be prepared to burn some steel. The advantage of a file is it is already hardened, unless you have a torch or forge that will be near imposable for you to do. The most important thing in knife making is the heat treating. The best steel wont perform like it's supposed to. If you decide to use a file grind your blade out, keep the steel cool; do not let it get any color in it (brown, blue, purple) as this destroys the temper. When your finished put the blade in the oven at 400 deg for an hour. It should have a good hardness for a knife then. As for me, I use old car springs(5160), saw blades(L-6) for many of my blades, Good luck.
Q:Trade in value for (scrap) steel?
Scrap steel is usually traded per ton. Average steel prices fluctuate on a daily basis. General prices for scrap steel are around $100 - $200 per ton. For daily scrap steel prices check the source below
Q:Design of Steel Building - ARCHITECTURE ?
Vinyl fiberglass insulation is getting popular with the steel building industry. The vinyl fiberglass insulation offers a shining look to the building and is resistant to dust as well as condensation. Effective ventilation inside the steel building can also help in preventing the condensation process inside the building. Besides, the building doors should be insulated effectively so as to minimize the heat loss. Be sure to seal all the door gaps in the building. All these steps are necessary to follow to get an effectively insulated steel building.
Q:How to sharpen a knife with the stone and the steel?
If you are lucky and have a whet stone block you need some patience water or light machine oil. Take your time and work in circular motion at a slight angle as to put an edge where you want it. I tend to think of it like polishing and work the length of the blade. If you work with a steel you are suppose to pull the blade across the steel at an angle. I have forgotten the angle but if you attempt this you soon find that you can associate a certain feel of the way the blade crosses the steel and know when you have it right and check the blade periodically until you have it the way you want it. There are some other sharpeners out there where you just draw the blade thru a device and they work as well. I was taught the old ways with the stone and the steel and don't know the actual prescribed angles but can tell you that you will be able to eye ball the angle and you don't have to use heavy pressure. These processes won't work on a serrated blade!
Q:Can fire resistant building materials burn hot enough to melt steel columns?
Gavin, the danger posed by steel columns and girders during a fire in a building, is not the danger of the steel melting but of the steel expanding and snapping the bolts that hold all of the steel together. Very high temperatures can be achieved in a building fire because the up-draft caused by the rising hot air, delivers a massive amount of oxygen to the burning carpet, paper and furniture. When a steel frame office tower burns, the heat expands the steel and snaps the bolts. This causes the building to fall-down and not necessarily, burn-down. I am too lazy to look-up the melting point of steel but it is not very high. That is one reason for the columns and girders in steel framed buildings, to be covered in asbestos (which is a fatally toxic material) or magnesium di-oxide.
Q:Will my damascus steel knife rust?
Damascus Steel Rust
Q:mild steel properties?
Be *real cautious* using HCL round stainless. A lowering acid like HCL will wreck down the oxide layer on the stainless, and corrosion will proceed. So far as i do know, there is not any scale down level at which HCL will not attack the skin oxide, however at very low concentrations maybe somewhat rust/pitting/corrosion is not going to be a main issue. Oxidizing acids like nitric, and to a couple measure sulfuric, will passivate stainless under the right conditions. But on simple, mild steels, corrosion will proceed to form FeCl and FeSO4 corrosion merchandise. The corrosion will haven't any outcomes on tensile, hardness or affect until ample fabric has been eliminated via corrosion to make a measurable change. Hydrogen embrittlement is a likelihood if there's constant anxiety, and hydrogen is advanced in corrosion. Whether or not it is a challenge would rely on the drawback.
Q:steel or aluminum horse trailer?
I have a steel trailer. It's okay but I think next time I'll go for aluminum because mine is rusting, particularly on the tongue, so the hitch gets all frozen up. Drives me nuts. Yeah, you pay sales tax on trailers and the dealership SHOULD give you temporary plates to get home, just like they do on vehicles.
Q:What are the uses of Mild Steel?
Mild steel doesn't really mean anything, technically. In today's world all steel is mild steel unless it's high carbon or alloy, which are mostly tool steels. You'll need to study steel much deeper than that to accomplish any real physics work relating to steel.
Q:Heat Resistant Chemical for Steel?
There is, but I don't know what it is made out of. It is probably some fireproof, foam material which acts like insulation. I doubt it is designed to resist abrasion however. Most things which adhere to metal surfaces are not flameproof, and those which do resist fire are not good insulators. For example, the ceramic coating of appliances like stoves and washing machines adhere very well and are fire resistant, but do not insulate. It was the failure of the steel insulation which caused the collapse of the world trade centers. The impact of the airplane tore away all the insulation on the supporting struts of the building and then the fire caused the steel to soften and break. Steel was once insulated by wrapping it in asbestos cloth and then applying plaster over this to form a shell. It did not actually adhere to the steel but it did insulate it, and was fireproof. However asbestos is a cancer hazard and a lot of old buildings are being stripped of their asbestos as a safety precaution. The asbestos can be replaced with fiberglass which is usually duct taped together.
