Product Description:

Galvanized Steel Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of Galvanized Steel Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, Galvanized Steel Coil is an essential fabrication component.

Q:What kind of steel alloy have the strongest attraction for magnets?
Magnet
Q:Surgical Steel Piercing Reaction?
Surgical Piercing
Q:Is blue steel stronger than stainless steel? i heard it is.?
Blue Steel is definitely stronger than stainless. Le Tigre and Ferrari are too. However, nothing compares to the strength of 'Blue Steel' to a non-ambi-turner.
Q:Cost of steel siding vs vinyl? Siding damaged from hail.?
I'm not sure of the cost but from experience having bought steel siding instead of vinyl for my home, if you can afford the difference it is well worth your money..I've had it for 25 years and it does hold up much better than vinyl!
Q:Why is Iron used to create steel? ?
iron came before steel. iron is what was discovered that, under certain circumstances, became a stronger metal: steel. that is why. its like asking why copper is in bronze. because what we call bronze, is an alloy of copper and tin. if you give a more detailed question, i may be able to give a more detailed answer.
Q:Is boron steel harder?
There is really no simple answer to this question. Boron is usually used for a handful of reasons, but most center on high volume low cost production of durable hardened steel. Boron is a very cheap way to get very durable parts with very minimal alloying of expensive materials. It was born of necessity during WW2 and is currently in WIDE use in bulldozer undercarriage. Probably in place of what would otherwise be 4140. Boron steel is quite a bit more difficult to properly heat treat. Better suited to mass production facilities with tight controls, but when done properly provides material just as durable as higher alloys. Not a backyard endeavor such as ht/tempering carbon steel or tool steels without appropriate homework and treatment controls.
Q:Steel or Iron? (stupid 20 characters thing)?
steel is harder than iron Iron is a chemical element. It is a strong, hard, heavy gray metal. It is found in meteorites. Iron is also found combined in many mineral compounds in the earth's crust. Iron rusts easily and can be magnetized and is strongly attracted to magnets. It is used to make many things such as gates and railings. Iron is also used to make steel, an even harder and tougher metal compound. Steel is formed by treating molten (melted) iron with intense heat and mixing it (alloying) with carbon. Steel is used to make machines, cars, tools, knives, and many other things.
Q:is stainless steel and surgical steel the same?
No it's not. I have worked in several different shops, selling body jewelry for years.-All inside malls- Every place I have worked (all specializing solely body jewelry) have used surgical steal. Not 100% on the grade for all items, but *most* were 316. Some items will be stainless or titanium. Typically stainless is cheaper and personally, I'd rather have a variety in metals because not everyone in the world is allergic to nickel, so why not have cheaper stainless items available for others? If you go up to any mall cart and tell them you have a nickel allergy, they should know to only show you surgical steal....unless they're idiots, which unfortunately some of them are. That being said, I have walked into tattoo shops and they have tried to charge me 35$ for a back and ball for my Monroe.....just a solid white gem.....The receptionist tried to argue with me on the quality of surgical steal, telling me, my products are lower grade and that's why she can charge me nearly 4x the amount. Well, I'm telling you guys, it's bullshit. I saw a display item in the original packaging and it was from the exact same company I ordered from. This was a very popular/redound shop in my area. They lie to push their product because they believe they can con you into buying it because they are the ones who pierced you (or in my case, sat at a counter and had me sign a few forms). It's just a bunch of **** guys...seriously, don't fall for it.
Q:What is purpose of providing steel in compression zone in Doubly reinforced beam ?
There are several reasons to add compression steel. Keep in mind, supported steel (meaning it can't buckle) resists compression as well. Compression steel helps reduce long term deflections. Concrete creeps under sustained loads. Steel lessens the compression, meaning less sustained compressive stress to cause creep deflection. It makes members more ductile. Since the steel takes some of the compressive stress, the compression block depth is reduced, increasing the strain in the tension steel at failure, resulting in more ductile behavior (the moment at first yield remains largely the same with compression steel added, but the increase in capacity after yield is significant). Compression steel insures that the tension steel yields before the concrete crushes, meaning it helps change the failure mode to tension controlled. It makes beams easier to construct. With bars in the top and bottom, you have longitudinal reinforcement in all 4 corners of the shear stirrups to keep them in place when pouring the concrete. Also, for continuous members, its often easier to run your negative moment steel the full length of the beam rather than trying to cut it off in the positive moment regions. Serviceability concerns. You're going to end up putting steel in that region anyway to for temperature and shrinkage.
Q:how to make carbon steel?
Carburized steel is not the same thing as carbon steel. All steel has carbon in it, but carbon steel is defined as Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 1.04 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. Carburizing is a surface treatment. Dropping hot steel in oil is oil quenching. It might get a little carbon in the surface, but oil quenching is mainly used as a slightly slower quenching process than water quenching, not for carburizing. Once it starts cooling down the carbon won't diffuse in. Quenching is used to change the hardness. The simplest way to carburize steel is to pack charcoal around it and heat it to 900 C or so. Industrial processes use a gas like carbon monoxide, but that's mostly just for easier process control.
