- Q: I asked a question last week about stainless steel and got some great answers. I combed all over the internet to try to figure this one out but could not find anything. What resists bending better: chrome vanadium steel (i.e. a steel commonly used to make tools) or stainless steel 304. My guess would be the chrome vanadium alloy but thats just a guess. Which on resist's bending better and by how much (#'s please :-)). Also, if anyone knows if chrome vanadium steel is cheaper than stainless steel 304 that would be awesome? I can't find a price per pound on chrome vanadium steel anywhere! Please help. Thanks in advance-Josh
- All okorder /... it can only be hardened somewhat by cold working. Bending stiffness is not proportional to tensile strength.
- 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: What are the common methods of testing the durability of steel coils?
- Steel coils undergo various testing methods to assess their durability, strength, and resistance to different stresses and conditions. Some commonly used techniques include: 1. Tensile testing: This method measures the maximum stress a coil can bear before breaking or deforming by subjecting it to tension. It provides valuable insights into the strength and ductility of steel coils. 2. Bend testing: This method evaluates the flexibility and resistance to deformation of steel coils by bending them to a specific angle and checking for cracks or fractures. It is essential for assessing coil durability in industries like construction or automotive. 3. Impact testing: This method determines the ability of steel coils to withstand sudden shocks or impacts. It involves striking the coil with a heavy object and measuring energy absorption or deformation. Impact testing helps identify coil toughness and resistance to sudden loading conditions. 4. Corrosion testing: Steel coils often face corrosive environments like moisture or chemicals. Corrosion testing examines the resistance of steel to degradation caused by these agents. Salt spray or electrochemical testing simulates and evaluates coil durability in corrosive conditions. 5. Fatigue testing: This method assesses the ability of steel coils to endure repeated loading and unloading cycles. It subjects the coil to cyclic stresses until failure. Fatigue testing is crucial in machinery or infrastructure applications where coils experience repetitive loading. 6. Hardness testing: This method gauges the resistance of steel coils to indentation or scratching, providing information about their strength and wear resistance. Common hardness tests include Brinell, Rockwell, and Vickers methods. 7. Non-destructive testing: In addition to the destructive methods mentioned above, non-destructive techniques like ultrasonic testing, magnetic particle inspection, or X-ray testing are used to detect internal defects or flaws without damaging the coil. By utilizing these testing methods, manufacturers and industries can ensure that steel coils meet the required durability standards and perform reliably in their intended applications.
- Q: Ik iron was too heavy but could steel bolts have been used. I can see iron dissolving at surface when to be a danger it needs to reach the core of sun.. But so does steel go deeper in(w.e alloy turned from iron)..I wanna know which would be worse iron..or upgraded iron(steel) and if the steel would have worse effects than normal iron..Im sure if we used iron we used steel
- 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: How are steel coils inspected for oil or rust residues using chemical analysis?
- Chemical analysis techniques can be employed to inspect steel coils for the presence of oil or rust residues. One widely used method is Fourier transform infrared spectroscopy (FTIR), which involves subjecting a small sample of the steel coil to infrared radiation and analyzing the resulting infrared spectrum. By identifying specific chemical bonds indicative of oil or rust residues, this technique can effectively detect their presence. For oil residue detection, a common approach is to examine the FTIR spectrum for a peak at approximately 2920 cm-1, which corresponds to the stretching vibration of C-H bonds in hydrocarbon chains. The observation of this peak signifies the existence of oil residues on the steel coil. To identify rust residues, the FTIR spectrum is scrutinized for characteristic peaks associated with iron oxide or hydroxide compounds. For instance, the presence of a peak at around 560 cm-1 suggests the presence of iron oxide (FeO) or iron hydroxide (Fe(OH)3). Apart from FTIR analysis, other chemical analysis techniques like X-ray fluorescence spectroscopy (XRF) or energy-dispersive X-ray spectroscopy (EDX) can also be employed. These methods provide information about the elemental composition of the steel coil, enabling the identification of specific elements linked to oil or rust residues, such as carbon or iron. In essence, the chemical analysis of steel coils for oil or rust residues offers a dependable and precise means of ensuring the coils' quality and cleanliness before further processing or utilization.
- Q: I understand that Stainless Steel is a low carbon steel having minimum 10.5% chromium content in it there r 60 different type of stainless steel. Kindly informa) Is this info correct?????b) Which stainless steel can get rusted or can have superficial rust????
- Stainless steel is a generic term for a whole range (there are more than 60 types) of Fe-Cr alloys. They all contain some amount of C and some alloys include a good number of other alloying elements. In almost all cases, the materials have corrosion resistance due the Cr atoms that are in solid solution with the Fe matrix. Under corrosive conditions, the Cr forms a thin tight coherent layer of Cr-oxide. This Cr oxide coating prevents further corrosion so long as it is not chemically or physically removed. If the SS has been subject to mechanical abrasion, the corrosion resistance can sometimes be restored by a light exposure to nitric acid which passivates the surface, restoring the Cr-oxide layer. The carbon content is an important factor in corrosion preformance but so is the heat treatment. Under the wrong conditions and in different environments, all SSs can rust. One of the most common corrosion problems is sensitization which occurs in the heat affect zone (HAZ) around welds. If the C content is high enough and the heat is high enough, the Cr atoms in solid solution form Cr-carbides and are no longer available to form a protective Cr-oxide. The corrosion resistance can be restored by appropriate heat treatment.
- Q: Can steel coils be stored in a corrosive environment?
- No, steel coils should not be stored in a corrosive environment as it can lead to the degradation of the steel surface and compromise its structural integrity.
