Q:Why was molton steel found at ground zero?
I think there are things that you are missing here. First of all I looked up the MSDS sheet for Steel from US Steel. Steel is made of all kinds of different metals to start with and the melting/freezing point for steel is 1750 F not 2800 according to US Steel. In addition in the World Trade Center buildings there were all kinds of other materials that are normally used in construction that were all burning at the same time which would have added to the temperatures. Not only was it steel but it was iron, calcium and other building materials too. NIST provides a maximum gas temperature due to WTC fires of 1,000 °C: In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, figure 6-36) Okay I don't know if you know who NIST is but that is the National Institute of Standards and Technology and they are some pretty smart people. They did not say that the steel melted due to the fires, but they did say that the temperatures surely did get high enough to to melt the steel. If US Steel says the melting point for steel is 1750 and NIST says that the temperatures were around 1800 F then that is high enough to melt the steel. I think the key is that there were other materials burning too.
Q:what is the diiferent in composition between mild steel and cast iron?
This Site Might Help You. RE: what is the diiferent in composition between mild steel and cast iron? I know that mild steel is more brittle than cast iron....but that is all.......please help? Thank you in advance......Ruby :D
Q:Steel Buildings?
Yes you can have a steel structure building, as if it is more economical than RCC, I think it is , and it is much faster in completion than RCC, For such area steel structure is less in time than the RCC by 30% to 40%, my experience could estimate 6months to 8 months duration for steel structure
Q:What does "steel roll number" mean?
The coil numbers in the steel industry are generally applicable to rolled round steel bars. A coil of steel has a specified length and weight. Different rolls have different volumes
Q:Steel Case V.S. Brass Case ammo?
If it's new you want to use quality brass ammo the first few hundred rounds. After that it doesn't matter. But do not you cannot use brass and steel in the same session. The lacquer tends to stay behind in the chamber, will fuse with the brass and you get torn case heads. So when using steel always only use steel that session and scrub the chamber down.
Q:Question for carbon steel ?
None. Mn is a trace impurity in all steels, if you look carefully enough. If you want to find a steel where Mn is not intentionally added, start looking at the alloy composition specifications, there are hundreds of steels. Why are you worried about Mn? Mn is typically added to steels for a very good reason.
Q:Bike Frame-Aluminum vs Steel?
Someone stated even the $99 walmart bikes are aluminum now. WRONG! Most Walmart bikes have steel frames unless you drop about $200.00. Personally, I prefer aluminum over steel. It's lighter, most times - just as strong and won't rust if you get a ding or scrape in the paint. See links below on Trek M/B. Trek 820 - steel frame - $329.99. Trek 3500 - aluminum frame - $359.99.
Q:Steel or nylon strings?
Musical type speaks volumes on the subject of this problem. Folks that want high quantity shall be unhappy with unamplified nylon string guitars. From my point of view, the elemental difference between steel and nylon is that this: steel strings ring and nylon strings resonate. The volume produced via steel is quite often a lot bigger than nylon however, to my mind-set, the sound resonance produced with the aid of the wooden of your guitar is essentially masked by steel strings. In case you have a decently made guitar (generally, around a thousand dollars and up), the sound interaction between the wooden and the strings in a nylon guitar is magical across the whole frequency range. With a steel string guitar, the sound produced via the vibrating string overpowers the timber resonance at all but low frequencies. In my view, i'll take a nylon string guitar any day for the sensitivity won from the interplay between timber and vibrating string.
Q:dose oxygen peroxide rust stainless steel?
Stainless does rust over time (EVERYTHING rusts it's called oxidation) Whenever something comes in contact with oxygen, the molecules will bond with the oxygen to form an oxide. Iron form iron oxide or rust which is reddish brown, apples turn brown after several minutes after it's been bitten. It all depends on the type of material used to manufacture the stainless. Stainless is made up of .2%-2% carbon, 11%%-28.5% chromium and iron. Some stainless is further advanced by adding other metals like nickel, molybdenum or niobium. Most stainless pocket knives are either normal steel coated with stainless or a cheaper form of stainless (it will have a high 300 number or very low 400 stamped on it). Other time, stainless will rust when a form of iron scratches the surface and contaminates the stainless, this is easily treatable if you get it quickly. Oxygen peroxide should not rust it, since the oxygen has already bonded with each other to form peroxide (2 oxygen molecules). It's the simplest form, but not the most stable (which means it could make your knife rust further). But I recommend steel wool or a scratch pad used to clean cook where (usually green or brown) to remove the rust.
Q:Do steel cartridge cases take less pressure than brass cases?
The ammo loaded in steel casing has a tendency to be loaded at lower pressures, for some reason. Most if not all of the steel case is of foreign manufacture. No reason steel can't be loaded to same pressures to that of brass, would probably seal better. Most of the calibers you describe in steel cases go in weapons with loose tolerances, like the AK. Lot of times, the steel won't seal in the chamber, creating blow by, putting crud in the chamber. This condition makes it hard to feed, chamber, and extract in a tight dimension chamber that is present in NATO weapons. AK's, due to more generous tolerances, won't be sensitive to this.. Weapons from NATO are of more tightly toleranced chambers like the AR, HK, Barret, etc. where brass is more reliable in sealing, and minimizes the blow by and keeps things clean, or at least more clean than a steel case that may not seal.
