Q:Is steel in spacecraft Ulysses?
Steel might have been used in some bolts sure. But.....are you under the impression that Ulysses was ever intended to crash into the Sun or something? You know it wasn't right? It was launched (in the 1980's) to study the Sun. But....uh.....not by crashing into it. Ulysses was even sent out to use Jupiter as a gravitational assist. We are closer to the Sun than Ulysses is..... Even if it did go crash into the Sun though there is absolutely no way that ANY material, natural or manmade, could survive intact all the way to the core of a star. It takes photons of LIGHT something like 100,000 years just to make it out from the core of the Sun to the surface because it is so dense. How do you propose a metal probe making it back the other way? Would it have worse effects than what? The effects, no matter what it was made out of, would be that as it got CLOSE to the Sun it would vaporize. No matter what it was made out of though it would have no affect whatsoever on the Sun. Every single element, without exception, that exists on the Earth and everywhere else in our solar system also exists in the Sun already, in far greater quantities. The planets and Sun all formed out of the same nebula at the same time. The Sun just got massive enough that fusion began and it became a star. There is already more iron in the Sun than there is everything on Earth. If you took every single atom of every element there is on the Earth it would still not add up to even a fraction of the total amount of iron in the Sun.
Q:WHY Is diamond stronger than steel?
Because diamonds are denser but a lot more brittle they would break if used the same as most steel also they are vary rare so useing them in mass production would be redecliously expencive.
Q:difference between titanium and stainless steel?
Stainless steel is more corrosion resistant than steel and titanium is more corrosion resitant and lighter. However, titanium is more prone to picking up (scratches caused by normal tools creating scratches and leading to stress fractures). The Lockheed Blackbird had to have tools treated lithium grease (i could be wrong) to prevent this. I'd stick with stainless steel as i think any titanium exhaust you can buy will be a titanium composite due to its cost
Q:advantages and disadvantages of steel structure?
Disadvantages Of Steel
Q:examples of some common alloy steels, what are their compositions and properties?
Steel is an alloy consisting mostly of iron, with a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten.[1] Carbon and other elements act as a hardening agent, preventing dislocations in the iron atom crystal lattice from sliding past one another. Varying the amount of alloying elements and form of their presence in the steel (solute elements, precipitated phase) controls qualities such as the hardness, ductility, and tensile strength of the resulting steel. Steel with increased carbon content can be made harder and stronger than iron, but is also less ductile. H.
Q:TRAGUS PIERCINg?!Stainless Steel?!?
Titanium is better, and most piercings heal better with titanium used jewellery.
Q:What steel is the most magnetic?
Silicon steel is the most magnetic material for making into transformer cores and motor cores. It contains 1.25 to 2.5% Silicon. Silicon steel is usually rolled to 2mm plates as lamination material. Iron may be magnewtic but it has low resistivity. With high silicon alloyed to iron resistivity is increased and core and hysteres are losses reduced. Important silicon steels are designated as AISI M15, M19,M22 and M36. In ASTM, these steels are designated 36F15, 36F18 and many more.
Q:Purchase Steel - For Construction Purpose?
It has been a few years since I was in the business but I have found that some steel from some countries can be quite different from the standards steel made in the US. For instance, one in 5 of my Indian made cast iron fittings would break when tightening it down. This never happened with US fittings. Even though I could take it back and get a refund, the increased price of US made materials was worth the savings in time and trouble. On a job in Columbia, the 3 inch angle iron came to us in 4 different sizes, all around three inches but not quite. This is not to say that all foreign metal is bad. One RD project I headed up we found a foreign bearing steel to be far superior to anything we could get in the states.
Q:Site that tells the history of Stainless Steel dining Utensils?
The booklet 100 years of WMF (WMF: Württembergische Metallwarenfabrik / Wurttemberg Metal Ware Factory) includes the patent application (or better: trade mark application) for stainless Cromargan Steel for the production of cutlery in 1926. Cromargan was the company's fantasy name for stainless Krupp V2A steel. Page 86 (unfortunately WMF is a German company, the booklet therefore is in German). Has nice pictures anyways. Appendix: I found the text (a bit cut however) in English language (without images and booklet, just HTML). See below.
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.
