Q:serious question! Dual-phase steel?
Dual Phase steels refers to a distinct group of alloys which are used for automotive bodies. These were developed to give improved deep drawing (for shaping) and strength while on the road. Most of the work was started at the same time in the 1970s as a response to the oil crisis (history repeats!) with SSAB in Europe, US Steel and British Steel leading the way. There are many variants of the dual phase alloys prefered by each of the auto manufacturers. The work on these steels led the way for TRIP (transformation induced plasticity) steels, rephosphorised steels and HSLA (high strength low alloy) steels. There is a distinction between these steels and duplex steels which typically refer to austenitic/ferrtic stainless steels. Also be aware that everyday low carbon steels with 0.1%-0.6% carbon will have a ferritic/pearlitic structure but are not considered to be dual phase So to summarise: Who - major steel companies worldwide When - from about 1973 onwards (up to around 1977 when the developments went in other directions) Where - Europe, USA and Japan (but I'm not sure who it was in Japan doing the work)
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 are cold steel swords made?
This Site Might Help You. RE: how are cold steel swords made? im buying a sword and i dont know if i should buy a cold steel sword or a normal sword and that i can some how make that cold steel
Q:Why are most homes framed of wood rather than steel?
Basically, it's because wood was available first and wood is still the cheaper, more widely available material. Way back when man started building dwellings similar to what we have now, steel was not an option for the masses. The process probably hadn't even been invented or perfected yet, there was not the widespread transportation of goods that we have today either. Early shelters were not even put together with nails, they use wooden pegs because metal was so expensive and not widely available. I can't say that it would be better for the environment; it takes a tremendous amount of electricity to smelt and produce metals. And you have the emissions problems from the factories and the power generation. I'd have to do more research on that one. A managed timber stand actually reduces greenhouse gasses and every scrap of that tree can be used in one form or another. The only energy expenditures are moving the trees to the saw mill, cutting at the saw mill and transportation of the goods after that point. And that would be a lot less than the power required to make the same number of feet of steel products.
Q:Mild Steel furniture finishing?
No, I don't think the oil will do what you want. I have heated and quenched metal in oil several times (to harden it) and it did not give a finish to steel. I have heard of heating steel to a high temperature (red) and putting powdered sulfur on it, it will make a black finish. BUT, sulfur stinks and you would not do this indoors. And I don't know what the results would be like for indoor use. At the hardware store, you can find something like POR (paint on rust), a brand name of rust neutralizer. There are others. You spray it on (or paint) and it will turn rust into a glossy black material. Other than that, I think paint is your best option. Check out the new finishes they have now, if you haven't checked, they have come a long way. If you let them dry completely (in the sun) the spray can finishes are very durable. Good luck! Ooops, I forgot about gun finishes. Yes, some are blue, you might be thinking of that, but that is only if you put several coats on. One coat might do it. Plus, there are other colors, such as black (see the parkerizing link on the list). Here is a good company, they can be lots of help, too.
Q:Fender Steel Guitars?
well, it was made sometime before 1981, because that's when Fender quit making 10 string steel guitars. Without any more information than what you've given me, it could be the Pedal 2000, the PS210, or the Artist Dual 10. Fender made steel guitars from the 1950s through 1981, so it could be from any time in there. I hope you have the pedals with it. The 10-string and dual 10-string models were quite expensive in their day. Unfortunately, if you're thinking of reselling it, you're probably not going to get a lot of money for it unless you find a pedal steel player, and like I said, having all the pedals is very important in that case. Anyway, hope this helped. Good luck. If I were you I'd learn to play it. Pedal steel players are always in demand.
Q:Is Steel crystalline in its makeup?

Q:What is the difference between LTCS and Carbon steel?
When exposed to elevated temperatures, quenched and tempered steels are more susceptible than normalized steels to permanent reduction in strength. This is especially true when exposure temperature begins to approach tempering temperature used when the parts were produced. In addition to losing strength, tempered steels also may experience reduced impact toughness after being exposed to long-term elevated temperatures. General belief is that this is the reason for LCC's reduced maximum allowable temperature limit of 345°C / 650°F in B16.34.
Q:Why can hot rolled coils be placed outside?
Because the stress of participation should be eliminated
Q:If you combine stainless steel with gold, does that make stainless gold?
Nope, Stainless Steel is a tradename for a certain alloy. Regular Steel, which is formed from Ferrous Oxide (via the Bessimer Process). The stainless part is because they mixed in some other compound to give it unique qualities. Gold, on the other hand, is a pure element, and it can form alloys with other metals, but there are no guarantees what the properties will be
