Q:How to repair corten steel?
6010 and 6011 Electrodes for welding galvenized steel. Weathering steel, best-known under the trademark COR-TEN steel and sometimes written without the hyphen as Corten steel, is a group of steel alloys which were developed to obviate the need for painting, and form a stable rust-like appearance if exposed to the weather for several years. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates continuously when subjected to the influence of the weather. In other words, the steel is allowed to rust in order to form the 'protective' coating. For welding corten steel: 1A.W.S ClassificationE 7018 - 1AWS A 5 - 1 - 78 2IS classificationE 5424 JXIS 814 (Part I II)H 3BS classificationE 51.54 B 12 17HBs 639 - 1976
Q:grain growth in steel?
There is such a thing as critical strain which will lead to extraordinary grain growth on annealing;but not without annealing.It would be to do with the density of grain growing sources and clearly the density of these nuclei woul increase with increasing severity of strain so I just of a guess that that those parts of a pressing with least strain might grow most.But I must tell you that in the case of Aluminium alloy extrusions severe and expensive coarse grain occurs near the surface and particularly toward the back end of the bar;so this would be where most severe deformation takes place.However in a pressed steel part you have all possible circumstances,some of which on ironed walls will resemble extrusion,others would be bending strains,tensile and compressive .I have to cop out of this now because as old wasname above,said it depends.But bear in mind that it is unlikely that the material you mention would be hot pressed,further .coarse grain might only be a surface problem and is likely to be cured by normalising so that new ferrite grows from austenite.A similar solution does't exisat for Al alloy extrusions,it has to be machined off.In a cold steel pressig you would only expect to see a cold worked sructure because the recrystallisation temperature of pressable steel would not be less than,say 550 degrees C .
Q:911 conspiacy theorists. Can fire melt steel?
They can't melt that fast At that temperature, the fire caused by the jet's fuel didn't hot enough to melt the concrete steel. As you see in the video the flame took only 20 minutes. The heat is not fast enough to penetrate all fragment of the concrete steel from top to the foundation, steel is not a good heat conductor like the iron. The explosion only took 5 stories, even all flame in all stories will take 4 hours to melt the core - in this case the core is the worst quality alloy which I don't think is used by WTC. The speed of the falling of WTC building was way too fast. It only took about 9.5 seconds. As an illustration, we throw an object - no matter the weight from the top of WTC, let's count how long it takes from the top to the ground as easy as senior high physics. We took the height of as h = 526.3 m, the gravity 9.8 m/s^2 then apply them to the Newton's equations, h = 1/2*g*t^2 then t = sqrt(2*h/g) = sqrt(526.3/9.8) = 7.32 seconds. The difference is just 2.2 seconds. The resistance of the concrete and solid materials should give at least 200% of the fall duration. WTC's 9.5 secs to fall is even faster a ball sliding on its wall from top the ground. I don't know what happened there. But my Basic Physics lecturer at first grade in my college -who concentrates in Materials- said that it is very odd that the flame burning 5 stories (at most 2% of 110 stories WTC) took only 20 minutes to melt the core of 30% after explosion top stories' core. A friend of mine, got summa cumlaude Bsc in civil engineering - concentrated in structure, said that the pan cake fall has never occured before due to fire causes. If the heat is hot enough to melt the core then the building should bend forward at a broad angle because the strain caused by the heat is not uniformly distributed along the building's core - remember steel is not a good heat conductor. I'm not speculatiing, but 9/11 is an odd tragedy
Q:How can a spider's web be stronger than steel?
Lol I dont know where you heard that, there probably saying for small insects like for instence a small instect in a spider web is like us( humans ) in steel but no I could break through a web with my soft hair or finger, like not an ant because there extremely strong but like a flea
Q:Steel sole combat boots?

Q:which is heavier: concrete or steel?
Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.
Q:What were some steel advances in industries? 10 points!?
The single most important important advance in steel production was learning to accurately control carbon content. This was done through the Bessemer Process in which air was blown through molten iron to burn out impurities and excess carbon. Low carbon iron (wrought iron) could be easily worked into shapes. Medium carbon iron could be cast into useful and durable shapes. High carbon steel could be used for structural uses (beams and girders). Adding alloys such as nickel and silicon could produce very tough steels and steels resistant to rust. Adding vanadium to steel engine parts allowed Ford to produce finely machined engines in huge numbers with existing machinery.
Q:Science help!?! steel wool experiment?
How to make it rust faster ? Adding oxygen to the water - bubbling air through it. Raising the temperature should make the reaction go faster, but I believe it also reduces the amount of dissolved gas. Adding salt, or an ionic compound like an acid, will accelerate electrochemical corrosion. That usually requires a less active metal, like copper, in contact with the steel, but variations in the composition of the steel may be sufficient to promote corrosion.
Q:Can you WELD STEEL to ALUMINUM? How much heavier/stronger is STEEL?
I can't weld steel to aluminum, and generally speaking I'd say the answer is no, however, there are some special procedures that can make a metallic bond between steel and aluminum, it can be done with explosive welding. A lot of multi-ply cookware is made with aluminum sandwiched between stainless steel, there is so much of it that I imagine there is another way besides explosives, but I don't know what. In any case it is not a normal workshop procedure. Steel is often considerably easier to weld, but it depends on the alloy. some steels are difficult to weld and some aluminum alloys are fairly easy, but on the average steel is easier. as far as brittle/ flexible it again depend on the alloy, some steels are less brittle than some aluminum alloys and the other way around. Steel does have a higher modulus of elasticity, so for a given size steel is stiffer, but that is for elastic deformation, for plastic deformation steel often has a higher yield strength, but some of the more exotic aluminum alloys can be stronger than low grades of steel.
Q:Does shooting steel case ammo in a AR-15 ruin/damage the gun?
No. People who say that don't use steel cased ammo. It it said its harder on the extractor. I don't see how. Its dirtier because it doesn't expand like brass does but the steel casing is still softer than the steel of the gun. That is a mild steel which isn't as hard as what most people are thinking of.
